Today I installed the Lexus Hitch on my new GX460. I ordered the kit from Sewell Lexus. I also used the instructions that Sewell provides on their website for a guide on the install. The document number is PT228-60100.
The instructions are written well, however the diagrams are lacking slightly in their clarity. Pictures would have been better, even in Black and white.
Here my add ons to these instructions.
1) Read the instructions page by page at least twice to make sure you understand the different lengths in bolts and bolt sizes provided the kit.
2) When you open the kit, organize all the parts in the correct grouping of size and similarity. It will make it that much easier as you go along:
3) You will need a small tool to remove plastic tab fasteners, roll of electrical tape, socket wrench with 12mm, 14mm, and 17mm. (I have air tools in the garage, so I used ½ ratchets on the 17mm and 14mm, and 3/8 on the 12mm.)
4) First thing to do is lower the spare and get it out of the way completely. I was shocked and grateful to find not only a full size spare, but also a correct finished rim on the spare tire. Now I can work that spare into the tire rotation.
5) Page 2 of the instructions (FIG 1-1) shows the tow hook that must be removed. You will reuse the hook, however the two bolts that hold it in, will not be reused.
6) On the same page FIG 1-2, shows the air compressor housing cover that must be unclipped. It is located on the outside of the frame rail behind the driver’s side rear wheel. (see picture)
10) Page 5 of the instruction sheet is very straightforward and easy to follow. Again remember to sort all the different length bolts ahead of time. It will save you from using the wrong ones in the wrong holes.
11) Figure 5-1 and 5-2 explain the final installation of the completed wiring harness. When you have completed the install of the harness it will look like this:
12) The balance of page 6&7 are easy to follow. Of special note is that the when you reassemble the air compressor cover, it will fit snugly and look out of alignment. The instruction sheet says as much as well, and that was reassuring enough to me, to believe I reassembled correctly.
13) The finished product looks like this:
14) Last note is the left over parts. This by design, not flaw. You will have the original harness mount, the two bolts that attached it to the cross member, and the two original bolts for the tow hook:
And that’s it. It took me just under ninety minutes on my back without jacking up the truck. I used a floor jack to balance one side of the hitch up against the frame while I lifted the other with my hands to get the bolts started. If I had to do this again, I’m quite sure it would be less than hour.
Of note, I am quite comfortable working on vehicles and have the air tools at the house. Pulling apart press clip fasteners is not exactly challenging for me. You be the judge, so you know when you are taking on too much of a job or not. If you are in Orlando and are completing this job, feel free to PM me and I’d be glad to drink your beer and supervise, ehh, I mean point out the highlights to ensure a smooth installation.
My owners manual shows using the spare tire in the rotation.
My 2 cents on Spare Tire Rotation. If you order Chromed Wheels, only four will be Chromed. If you do a Spare Tire Rotation, all your tires will wear out evenly. Problem is, if you want to change brands, you will have to buy 5 new Tires. Personally, I have them rotate front to back and always have a new spare, even though it may be a different brand.
