How to Install a Fifth Wheel on a 2005 Ford F-350


Today on our 2005 Ford F-350 Super Duty Crew Cab with an eight-foot bed, were going to be installing the Reese Quick-Install Custom Base Rails and Installation Kit for Fifth Wheel Trailer Hitches, part number RP50082-58. First, were going to begin our installation by removing both of the rear wheels as it will give our self a little more working room as well as allow you to see things a little bit better. Next, were going to need to remove the plastic wheel well liner thats installed on this vehicle. To do that, were going to need to remove several push fasteners. Go ahead and begin here in the wheel well ones. Im just going to use a trim panel removal tool or large flathead screwdriver will work as well.Next, were going to need to take one of our rails here.

Set it up into the bed, then were going to need to center it between the weld seam on each side. Just go ahead and use our tape measure to get that. Once we have our rail centered, well then measure from the rear of the bed, hooking it right there on the edge. Well measure up to the specified measurements per the directions. Now, that we have our bed rail in the correct position, go ahead and take our paint marker, and put four dots where were going to need to drill out our hole.

Go ahead and slide the rail out of the way.Next, well go ahead and take our eighth-inch drill bit, and well drill out the four locations. Next, were going to go ahead and take our side bracket. Were going to start over here on the driver side. Were going to make sure that these two holes we drilled line up with the holes in the bracket. You put it up into position.

It looks like everything is good. Well go ahead and double check over on the passenger side as well. Once weve done that, everything lines up, well go ahead and use the step-drill process to drill each of our four holes out to a nine-sixteen-inch drill bit. Now that we have one side drilled out, well go ahead and repeat the same process over on the other side.Now that we have our holes drilled out, were going to go ahead and come back down here into the fender well. Were going to hold the side plate up into position.

Were starting over here in the driver side. Now, the mounting location here on the side bracket that were going to use to attach, theres a square hole here. It lines up with the hole in the frame. Now with the hardware that comes with the kit, not all pieces will be used for every model of your vehicle. Keep that mind that you may have some additional pieces left over at the end of the installation.For example, on this location right here, some model years have a spacer that goes underneath it, but our model year does not require that spacer to be installed. Were going to go ahead and take our five-eighths carriage bolt. Let it go through the hole. Then on the backside, well be using the spacer block that looks like this, a five-eighths lock washer, and a five-eighths hex nut. For now, were just going to hand-tighten down everything. Go ahead and repeat the same process, both the driver and the passenger side. Next, were back up in the bed where were going to need to install this U-shape spacer as well as our half-inch carriage bolts.Now, well need to align the spacer like this at each hole. With our spacers emplaced, we can go ahead and set the rail back over the top, lining up the hole. We can then take our carriage bolt, slide it down through. Well repeat that over here on the passenger side. Next, we can go down underneath the vehicle. In each of the four carriage bolts that we installed, on the underside, well be putting a spacer block that looks like this, half-inch lock washer, and a half-inch hex nut. Although were not going to completely tighten the hardware down for now, we do want to make it tight enough that the rear rail will not move around as we need that to stay in position for placement of the forward rail when we get to that point.Well go ahead and repeat the same process over on the passenger side. Now that we have the hardware installed loosely on both sides, youll see how the little U-shape spacers are actually causing the rail to sit up high here which means underneath, theres going to actually be an air gap, and when we tighten everything down, it will actually crush the bed; so were going to go ahead and pull the spacers out here on the topside. Theyre actually going to be installed on the underside of the bed. Well actually put it around the bolt and go up in there like that. Well go ahead over on the passenger side where well repeat the same process. Now that we have our spacer blocks in, we can go ahead and tighten down the bolts a little bit to hold everything in place.Next, were going to go ahead and install the U-bolts. Go here and here, and feed through from the inside out. Were installing a conical-toothed washer, making sure the teeth face towards the hitch, and a half-inch hex nut on each half of the U-bolt. This will be the same process for both the driver and the passenger side. Go ahead and snug them down for now, enough so that its not moving around. Now, we can go ahead and repeat the same process over on the passenger side. Next, were going to go ahead and come up into the bed. Now, weve already installed the fifth wheel head section into the rear rail here. This is actually the customers. We are reusing this, so this part here is not new.Normally, you would just not put the whole head section on one to make it a lot easier to move around as we need to use this section to set the distance for the front rail. Go ahead and lift it up, and align the two tabs on the front side into the slots in the rail. Were going to go ahead and just tilt it forward a little bit. Slide our rail up, so that it drops into position. Now in addition to setting them in here, we need to push the rail towards the rear, so that its tight, so theres not a lot of movement inside the slots in the rail. We also need to again center between the weld seam on both sides. That way, we know when we drill our holes here that well line up with the bracket underneath.Now with our rail in the correct position, were going to again need to drill out the four corners. Well again mark the four locations. Im just going to use our paint marker here. Now with our four locations marked, we can go ahead and set the head out of the way as well as slide the rail out of the way where well drill out the holes. Starting with the eighth-inch bit and ultimately ending up with a nine-sixteenths. Well go ahead and take our eighth-inch pilot bit, then were going to use a half-inch drill bit to go through the hole because its the same size as our bolt. With the hole drilled out, we can then go ahead and take another half-inch carriage bolt. Drop it down into position. Well then move to the forward hole where well go ahead and repeat the same process.Next, were going to go underneath the vehicle. For the two center locations, theres one here and the forward rail here, well be installing a half-inch conical-toothed washer and a half-inch hex nut. Were just going to put them hand-tight for now. Again, were going to go ahead and start here underneath on the driver side. Well take our U-shape spacer, slide that up into position. Well go ahead and put the forward U-shape spacer in there as well. Go ahead and put the round toll spacer, the half-inch lock washer, and a hex nut on both. Now that we have the hardware installed over here on the driver side, we can go ahead and repeat the same process over on the passenger side.Now that we have all of our hardware installed, were going to come back, and theres a specific order you need to torque things down in. We need to tighten down the bolts or the hardware that attach the cross rails to our frame brackets here first. Once all of those are tightened down on each side, well then come back and tighten down the hardware that attaches the side plate to the frame. While youre tightening down the hardware, before you torque things down, make sure you dont forget the two center bolts as well. Now with our hardware tightened down on the driver side, well repeat the same process on the passenger side.Now that we have all of our hardware tightened down, well go ahead and torque down the hardware in the same order that we just tightened everything down. Now that we have all of our hardware tightened down and torqued to the manufacturers specification, now those fender liners we're an aftermarket fender liner, so your particular vehicle will probably not have them in it. The customer on this application has decided not to reinstall them because you will need to do a bunch of cutting in this area for them to go back in properly. The final step will be to reinstall the wheels and tires.For installing the fifth wheel hitch, you want to refer to your owners manual for the particular hitch that youre installing. Now that our wheels are back on, that will do it for the installation of the Reese Quick-Install Custom Base Rails and Installation Kit for Fifth Wheel Trailer Hitches, part number RP50082-58 as installed on our 2005 Ford F-350 Super Duty Crew Cab with an eight-foot bed. .
