How to Install a Trailer Hitch on a 2002 GMC Sierra


Today we are going to be installing Curt hitch part number 13322 on a 2002 GMC Sierra. The first thing you want to do is go ahead and lower the spare tire to get it out of your way. OK, we are looking at the drivers side of the vehicle here. At the bottom of the frame you can see we have got an existing bolt. We are going to be removing that off both sides of the vehicle, and we will be replacing that with new hardware. Just forward of that is an existing hole as well that we are going to be using a carriage bolt and block - just it down from the top of the frame, down into place. And then here on the bumper itself we have got two existing weld nuts. Those are going to provide the rear-most attaching points for the trailer hitch. And again, we are going to be using the hardware that is provided in the installation kit. We will go ahead and take our carriage bolt and block and that into place. The next thing we want to do is go ahead and remove the bolts from the end of the frame rail on both sides, and then we can go ahead and put the hitch up into position. We are going to replace the bolts that came out of the frame with the new 14-millimeter bolts, along with the conical-tooth washers. We are also going to be using those bolts in the bumper as well.

OK, we are going to go ahead and put the hitch up into position now. It helps to get the proper order of operations here to make the install easier. I first attached the carriage bolts at the forward-most attaching point. Now I am coming back and doing the ones in the bumper second. That will help to get them aligned easier. And then we will come and do the weld nuts in the bottom of the frame last. We want to leave everything loose for the time being until we get all the bolts in. OK, with all the bolts in place, we can go ahead and tighten them up. And now that we have got all the bolts in place, we can go ahead and torque them down. You want to check with your directions to verify the appropriate torque rating for each individual bolt. OK, now that we have got all the bolts torqued down, you just want to make sure you put your spare tire back up into place, and your installation will be complete. This will conclude the installation of hitch part number 13322 on a 2002 GMC Sierra.
