I decided to do this mod after I read Jason's post http://www.toyota-4runner.org/4th-gen-t4rs/87150-4th-gen-seat-not-comfortable-you-wish-easy-mod.html
I am 6'1" and the current seats are not comfortable enough. I have an SR5 with manual seats so I thought this was a great idea, especially for the passenger seat. I took his idea a step further though and installed about 3/4" spacers under the front of the seats. The results are awesome. The passenger seat is so much more comfortable. Ok here is the write-up. And keep in mind this only cost about $5 and 2 hours.
- Get 6 new bolts. With the added spacers the stock ones don't work except in the back. See attached pictures for approximate size. Menard's, Ace, Home Depot, did not have the bolts so I went to an industrial fastener store. Keep in mind that it's an automotive bolt not a home improvement bolt so make sure the threads match.
- Get 44 washers. 11 per bolt (10 for space and 1 for use as the washer)
- Get tools. Ratchet with extension will be needed.
1. Take off front bolts only and then sit in the seat and rock it backward about 3 inches with the rear bolts in still. Be careful not to break anything. This helps by bending the bars underneath and starting to get them in the correct position.
2. Take out rear bolts and start 2 of the new bolts. Do not tighten them, just start them.
3. Go to the front and get new bolts and washers and "spacers" in the correct order and then start those bolts. This will probably take a little "fineagling and shimmying". By using the longer bolts in the rear and barely starting them it will be easier to get all 4 started.
4. If you are having trouble getting the front ones started remove the rear bolts and just get the front ones started.
5. Once you have all 4 started get working on tightening them. I recommend tightening the fronts first. Tighten all of them.
6. Once you have all 4 tightened take out one of the rear bolts and replace with the stock bolt. Then tighten the stock one and then go to the other side and do that one.
7. Do the other seat.
By using the longer bolts first and tightening them all down before switching back to the stock it is a little easier. ( My own little trial and error method)
Took me about 2 hours. I just did it on my lunch break.
