How to Install the Fastway e2 Weight Distribution System on a 2016 Ford Flex


Hey everyone, Shane here with etrailer.com. Today I have a 2016 Ford Flex. I'm gonna walk through how to install the Fastway e2 weight distribution system. A weight distribution system is gonna provide a lot of different things for you. A lot of good things for you, and you can see with our trailer set up now without a weight distribution system what it's doing. The front of the vehicle was raised up the back of the vehicles down, the nose of the campers down and the back of the camper is up.

Well, what that's doing is on the front of the vehicle creates uneven front tire wear, makes your steering light and affects your braking. The weight being down on the front if you hit a bump could cause some of the items up here in the front to maybe hit the ground. Maybe you hit a dip in the road, something like that. When it raises the back and you have two axles on the trailer like this, what it does it's putting more weight on the front axle and not putting enough weight on the back axle. And it's gonna create uneven tire wear for that front axle and it's putting too much weight on it.

So what we wanna do is we wanna get the back of the vehicle up towards riding level, the front of the camper up towards riding level so that the axles on the trailer are getting the proper amount of weight distribution and we're getting the proper amount of tire wear on the front end, we have proper braking and proper steering. There's a couple of different kinds of weight distribution systems. You have weight distribution that just weight distribution, which again, just transfers the weight back on the trailer so that your vehicle and trailer are riding level problem with those are, is the only way you have to control a sway situation is with a brake controlling, and a sway situation is because the trailer is so tall if you get a crosswind or you get vehicles that are passing you, whether it's coming the opposite direction or going the same way just going a little bit faster it creates wind in there, the back of the trailer starts to move, the tongue of the trailer moves the opposite direction and starts moving the vehicle, it's hard to steer the vehicle and it's hard to control the trailer can cause a very serious accident if you can not control it. A weight distribution with sway control will eliminate the trailer swaying so we don't have the back of the trailer moving, the tongue of the trailer moving and the vehicle moving towards hard to control. I had a situation I just recently bought a camper and had weight distribution.

When I went and picked it up, it wasn't set up correctly for my vehicle, which I knew that, but I didn't have the proper tools with me at the time. I had a brake controller already in my vehicle I was on my way home, which wasn't very far, but when I got on the highway, I noticed that the back of the trailer kept swaying. I used a brake controller and kinda feathered it so it applied the brakes on the trailer and it brought the trailer back center again, but every few 100 yards it starts to sway again, which means that the trunnion bars we're not putting enough pressure on the back axles of the trailer, on the axle of the trailer. I had too much tongue weight. So once I got home I readjusted it.

I don't even have to touch my brake controller anymore because I don't have any more sway in the trailer. Now that we've got our weight distribution system installed and set up, you can see our trailer is level our vehicles level, which means we're gonna have a much safer, much nicer ride. We're not gonna be wore out when we get there. We don't have to worry about the sway on the back of our trailer, scaring us while we're driving down the road. This is how our weight distribution system is gonna look like when it's installed, you can see we have an adjustable head on it so it allows us to adjust the angle, to get our trailer as level as possible. The round bars or spring arms, if you foul them back there on an L bracket while the bottom of the spring arm or round bar in the top of the L bracket there's like a padding, it's almost like a sandpaper and that's what is for your sway control. As the vehicle or the trailer starts to move those two create friction and when they create friction, they stick together. And that keeps the back of the trailer from moving back and forth or swaying. Our spring bars if you noticed they're gonna be round up here and flat towards that end. The round part actually locks into place up inside of this sleeve. To release them once you have the weight off of the camper, you have the spring bar off of the L bracket, this little loop right here or hook, you're gonna pull out on it and it's gonna allow this bar to slide out the bottom. This setup is gonna come with everything you see here with the exception of the ball, the ball you need to choose for the size couple that you have. Also, this setup is gonna require inch and a quarter shank. So whatever ball you choose, make sure it has an inch and a quarter shank. You can find those here at etrailer. The whole system is gonna be constructed out of a steel so it's gonna be very durable, has a nice black powder coat finish so it's gonna stay looking nice, stay working great for you for a really long time. As far as the installation process can be a little bit trying, kinda nerve wracking, having to make all these adjustments and everything, but once you get it figured out, you're gonna be much happier because your trailer is gonna tow much easier. This particular setup is gonna have a 600 pound tongue weight or max tongue weight and a 6,000 pound gross trailer weight. As I mentioned before, you wanna make sure that the vehicle can handle whatever trailer you're pulling, but the weight distribution when you pick one out, I like to recommend figuring out what the gross vehicle weight rating of the camper and you wanna go above that. You don't wanna go too high, you just wanna go above it a couple 100 pounds maybe so that you know that your weight distribution is in the middle of the handle the weight that you put on the trailer. Now that we've gone over some of the features, let's walk through how to get it installed. To start your installation you wanna make sure your vehicle is unloaded. It doesn't have any weight on it from the trailer. We want the normal ride height. So what we're gonna do is we're gonna measure from the ground, the top inside here and we're gonna take note of that number. Now we're at 32 and a quarter. We can go ahead and take a note of the front as well. The front we're at 30 and three quarters. Next we need to get our trailer level. What we're gonna need to do is we need to measure the frame rail underneath the camper. Make sure you don't measure it by the tongue because some tongues could be welded underneath or above the actual frame underneath the camper. So we're gonna measure the front, we're gonna measure the back and we wanna get the same number. Once we have that level, then we're gonna move up and we're gonna take a measurement of the coupler. Next we're gonna get the shank out of our kit, we're gonna put it onto our receiver. For this vehicle because it sits so low we're gonna use it in the rise position. We're gonna measure with our camper level, we're gonna measure to the top of the coupler. Looks like the top of our coupler is at 19 inches. We're gonna take this guy here and we're gonna put it onto our shank and we want the same measurement here at the top of the ball. We're gonna have two large bolts with four large conical tooth washer. We're gonna put one conical tooth washer on the bolt. Make sure the teeth are facing in towards the hitch or the receiver. Go ahead get one slid in place on the opposite side, gonna put another conical tooth washer, make sure the teeth are facing towards it again otherwise you're gonna loosely install the nut. We'll go ahead and measure that and see where we're at. Right now we're at about 18 inches so we're gonna come up one hole. Right now our ball is just about at 19. So we'll go ahead, get our second bolt put in place, it's gonna go in the bottom here. Next you're gonna have a pin in your kit it's gonna look like this, and you're gonna have seven washers. We're gonna start with five right at the top here between the shank and this mount there's a hole. We're gonna take this with the washers we're gonna slide it down into place. We're gonna take it, we're gonna push it all the way up, and there's a bolt on the bottom, we're just gonna tighten it so it holds it there. Gonna go ahead and take another measurement and it looks like we have too many washers so we're gonna pull a couple of them out. What we're trying to do is try to get this ball up as close to 19 inches as possible. Right now what it's doing is it's pushing the ball back and it's dropping it just a little bit. Right now with three washers, we're perfectly set at 19 inches. So now we can come back and we can start tightening down our hardware. We're gonna take an inch socket, the bolt right down here in the bottom we're gonna tighten it, but we don't wanna tighten it so much that it actually binds up. We just wanna tighten it against the shank. What it's doing is as you tighten the bolt, it pushes out the bottom and forces the top and that pin up against the shank so it's tight. Once you get that tight, we're gonna come back and we're gonna tighten these. We're gonna use an eighth of an inch socket and wrench, or if you have Impact you can use those and then once we get these tight, we'll come back and then we'll torque them. So next we're gonna take these two brackets, the single holes we're gonna put them together like that, gonna take a bolt, gonna slide it through, on the other side, we're gonna put a lock washer and a nut. We're not gonna tighten this on all the way. We're gonna take it and set it over our frame rail. Depending on the coupler that you have if it's a lower, if it's a bottom mount, this is gonna mount this way where these two are on the bottom. If it's a top mount like we have here, they're gonna be on the top. We're gonna take our second bolt gonna fit like this through the other bracket and then I'll put the same hardware on the other side, lock washer and then a nut. And again we're just leaving this loose for now. Next we are gonna take a tape measure, we're gonna measure from center of our coupler, along the frame rail, back. We want that number to be as close to 24 inches as possible, but absolutely no farther than 27 inches. You have an obstruction like this you can go farther than 24 as long as you don't go past 27. Ideally if your trailer tongue weight is under 800 pounds, you wanna be lower than 27 inches. And again, we have an obstruction, so we really don't have an option there. We're right at 27. So now what we're gonna do is we're gonna tighten these two bolts. So we lock this in it's place. Three quarter inch wrench socket will tighten it into place. Once you get them tightened you're wanna come back and you wanna torque these to the specifications in the instructions. And we're gonna have an L bracket that looks like this. We want at least two holes showing above the frame rail. We're actually gonna go ahead and do three. We can always adjust this down if we need to. Put on the nylon lock nuts, same three quarter inch socket will tighten them down. Once you get one side done, you repeat that on the other. Next we're gonna get our bars in place. We're gonna take them from underneath we're gonna slide them up so they clip. Turn them out like that, then what we're gonna do is we're gonna couple the trailer onto the vehicle so we'll go ahead and raise the tongue of the trailer up. Now, if you notice once I have it coupled I'm using the tongue to raise up the back of the vehicle, you notice where our trunnion bars are, they're really low. So what I'm gonna do is I'm gonna take these I'm gonna drop them down in one hole. I decided to go ahead and drop these down even one more hole so I had two holes in the bottom, two holes on the top. Just from experience and looking at it I knew the way these bars we're sitting. They we're gonna sit at too much of an angle once we put them on and drop the weight down on them. So we're gonna try and like this we can adjust them as we needed. If it's not enough we can always put them back. We have a bar here that comes with your kit, and this to help you get the bars up on the L brackets. You're gonna stick that tip right in that hole. You're gonna pop it into place like that. Once you get it adjusted correctly, you're gonna have a pin that looks like this and slide this in with the hole down, and you're gonna have a clip, that will lock it into place, and make sure you have one on each side. Once we get everything installed and adjusted to where we want, we can go ahead and uncouple the trailer from the car and then we're gonna torque down the two bolts to the specifications listed in the instructions. Now, a couple of things that I had to do to adjust it to this vehicle is this L bracket, which I adjusted last. I have five washers where the pin is, I have it on the third hole down, so it leans a head back just a little bit. We want our spring arms to be parallel with the trailer frame and we want our L bracket. So in order to adjust the spring arm or the round bar to be level or parallel with the trailer frame, we can adjust this bracket. So that's why I adjusted this down to the last one and you can see my spring arm or round bar is parallel. Now as far as the measurements go, trailer is level, the back of the vehicle can actually be within one inch. The front of the vehicle is more important than the back. You wanna make sure that the front of the vehicle is as close to that factory ride height as possible. That's gonna do it for our look at and installation on the e2 weight distribution system on a 2016 Ford Flex..
