How to Install a Trailer Hitch on a 2006 Buick Lucerne

Today on this 2006 Buick Lucerne, we are going to be installing Draw-Tite hitch part number 36309. And this installation will also apply to Hidden Hitch part number 90140. OK, we are underneath the vehicle and we are taking a look at the driver side frame rail. We want to go ahead and point out the mounting location for the trailer hitch. The first thing that I want to note is that we do have exhaust here, right in the way of the frame rail. And on this particular vehicle, we do have dual exhaust. So, it is the same on both the driver and passenger side. We do need to lower the exhaust down. In doing so, we want to go ahead and take and remove the bolt at the rear portion of the frame here. And that is going to lower down the exhaust bracket. We want to do that on both the driver and passenger sides for dual exhaust models. Before lowering the exhaust hangers though, I do want to go ahead and put a support strap across the main exhaust tube here, at the forward side of the vehicle. The reason is, once you remove the exhaust off of its hangers, it could put additional strain on the forward exhaust hangers and possibly allow it to fall and damage the exhaust. 0:55

We next want to go ahead and take and remove the exhaust bracket from the exhaust hanger here. These are actually going to sit off to the side and they are going to be replaced with new brackets that are provided with the installation kit. This is going to help lower the exhaust down and prevent it from knocking against the hitch. And to install the new bracket, we are going to use the 7/16 carriage bolt, along with the flange nut. What we want to do is take it to where it is curved down and this portion is going to be attaching to the bottom of the frame, along with the trailer hitch. And you want to repeat that process for the passenger side on models with dual exhaust. And with the brackets in place, we can go ahead and show you how the hitch is going to mount. We are going to be using this existing weld nut here that was holding the exhaust bracket up into place. We are going to use the new 10 millimeter bolts that are provided with the installation kit. And again, the hitch is going to go in between the frame and the exhaust bracket. And with the hitch in position, we are actually going to drill a hole here at the forward side of the frame. You will note here on the passenger side you likely have either a heat shield or, in this case, a load leveling bracket which need to be trimmed before we can put the hitch up into position. You want to check with the directions to verify the specific area that you need to trim out to make clearance for the hitch. So we are going to go ahead and do that next. With the load leveling bracket that we have here, I am going to just need to go ahead and remove this rear bolt that is holding it into place. And you will see that we need to cut out about 2-3/4 inches of the load leveling bracket here out even with the outboard side of the frame. 2:29

We will go ahead and put the hitch up into position now. We do not need to necessarily need to hook it up to the exhaust brackets just yet. I am just going to hold it up into position with 10 millimeter bolts long enough to use the hitch as a template to drill our 1/2 inch holes out at the forward side of the frame. And then we will go ahead and remove those bolts. The reason that we are keeping the hitch independent of the exhaust brackets at this time is to insure that we have enough room to get our drill bit into place. If we were to put the exhaust brackets up right now, the exhaust would be right in the way of where we are trying to drill. With the hitch up into position, now again, I am going to go ahead and drill out my holes. We are going to be drilling these holes out to 1/2 inch. I am going to start by using a 1/4 inch pilot bit and then go ahead and enlarge it to 1/2 inch after that. Next, we want to take the 1/2 inch carriage bolt, along with the 1 by 3 inch block, and go ahead and fish it inside the frame and down through the hole that we had just drilled. We are going to use one of these two large square holes on the outboard side of the frame as our access hole to accomplish this. And to do that we can either use a 1/2 inch bolt leader, which is not provided in the installation kit on this vehicle, however it can be purchased here at, or you can make your own bolt leader. And I am going to show you how to do that. What I am going to use is just a lightweight piece of what they call stove wire, which can be found at any hardware store. We will take one end of it and feed it from the bottom of the frame through the hole we just drilled and back out the access hole out the side of the frame. Next we want to take the carriage block, go ahead and feed it on to the bolt leader and we can just let it sit inside the frame. We will next take the end of the wire and our carriage bolt and we are going to take and actually wrap the threads of the carriage bolt with the wire. And what I am doing again is just getting inside the thread groves and just wrapping that around just like so. And then we can take the other end of the wire now and use it to pull the bolts and block into position. And we want to attach the hitch to the carriage bolt using the lock washer and hex nut. And then we just want to repeat that for the passenger side as well. 4:49

And then next we want to go ahead and actually torque our 1/2 inch carriage bolts at the forward side on both the driver and passenger side. And then we will take and come back and remove the bolt here at the end of the frame and put our exhaust brackets up. Again, we are doing it in this order to maximize the clearance that we have to torque the bolts down. You want to check with your directions to verify the specific torque rating for each of the bolts. The carriage bolts are torque now. I am just going to remove these 10 millimeter bolts from the end of the frame. And you want to do that on both the driver and passenger sides again. And then we want to go ahead and lift our exhaust system back up into position. OK, and then we want to take the exhaust bracket and, aligning it under the hitch, go ahead and put the 10 millimeter bolt back in. And with the bolts torque down, our installation is complete. You just want to make sure that if you put a strap to support the exhaust that you remove that as well. And now that we have our hitch installed, we want to go ahead and give you a couple of final dimensions that will help make choosing your hitch accessories a little bit easier. From the top of the receiver tube opening to the ground is going to measure 12-1/4 inches. And from the center of the pin hole to clear the rear edge of your bumper is going to be approximately 7 inches. And that will conclude the installation of Draw-Tite hitch part number 36309 on a 2006 Buick Lucerne.
