Today we are going to be installing part number 87458 from Hidden Hitch on a 2007 GMC Canyon. When installing the trailer hitch, the first thing you want to do is to go ahead and lower the spare tire to get it up and out of the way. Looking over here at the passengers side frame rail, we are going to go ahead and point out the mounting location for the trailer hitch. As you can see here on the side of the frame, we have got two existing bolts that are holding the bumper onto the frame rail. We are going to be taking these two bolts out and putting the hitch up into position, and those provide the two side-mounted attaching points for the trailer hitch.
We are going to use this existing hole here at the bottom of the frame. We are going to take the fish wire that is provided in the installation kit. We are going to feed that through the hole and out through the access hole in the side of the frame here. OK, and then we just want to put the fish wire through the block and then wrap the threads of the carriage bolt with the fish wire. And we will just pull that through. With the fasteners in place and the bolts removed, we can go ahead and put the hitch up into position. I do want to note before we start, you can see we have got a close-up here of the carriage bolts that we had put in place. You can see where the crossmember meets the frame here, that there is typically a decent-size weld that makes this a little bit of an offset when the hitch goes up to meet the frame. In order to take that out of there, we want to add some washers. You can add one or two, as needed. But basically you want the bottom of the frame to be even with the crossmember there.
OK, now I am going to go ahead and put the hitch up, and I am going to start by hanging it from the carriage bolts. I am just going to loosely install those for the time being, because, again, I do have to add those washers in. OK, and with the carriage bolts loosely installed, we want to go ahead and attach the fasteners to the side of the frame. In these positions, you are going to note that the hitch is very wide, and you have got a lot of space in between the frame and the hitch itself, because we do need to add these large blocks in between the frame and the hitch. To feed our new hardware into position, we want to use the new hex bolts and conical-tooth washer, and I am just going to go ahead and loosely thread those in, just to get it started. OK, and here on the drivers side as well, you can see we have got some interference with the crossmember when I put it up. It looks like on the drivers side here I may only need to use one washer.
All right, and with the bolts in place, we can go ahead and snug them up. And with all the bolts snugged down, we can go ahead and torque them down now to their specified torque ratings. You want to check with your directions to verify the appropriate torque rating for each individual bolt. And with all of our bolts torqued down, our installation is complete. You want to make sure you put your spare tire back up if you had removed it. This will conclude the installation of hitch part number 87458 on a 2007 GMC Canyon.
