Excellent advice! I'm currently taking the Manual Transmission & Differential class at my local CC, so I shouldn't have any problem setting the backlash & preload.
That is my first inclination. I guess if it goes together and I don't like the contact pattern between the ring and pinion I can take it to the shop for fine adjustment.
LOTB (lateonthebrakes) Order the diff directly through Eaton, and install it all your self, the actual process is VERY straight forward and can be done in a few hours. :top
o take a word of caution....
Take from someone who tried going the cheap route, and doing it themselves.... As much as it sounds appealing to do the final adjustment check your self, just take it to a shop and have them do the adjustments. If you wanna install the Trutrac your self, go for it, but id just take it there with everything ready to go, and pay them to set the back lash and what not. That will be MORE then enough evidence to prove it works. Our style diffs require is shim kit, and with out, getting it spot on is impossible with out the shim kit....you might get lucky, and it wont need any adjustment, though that is almost never the case....Older style Toyota diffs, you turn two nuts on each side to adjust the backlash/preload.... a new ring and pinion aint cheap, and it IS NOT worth gamble, do it right the first time...:top:
Here is a tip, LOTB, if you do it your self... place your ring gear in the oven @ 180 degrees for about 30 min, it will slide right over the diff no problem, as it is an interference fit. Make sure you start all 12 bolts before it cools down too much. torque in a star pattern AND in a couple steps, like 30lbft, 60lbft, then final 92lbft. Lock-tite is not a bad idea on the threads either....
LOTB, this attachment is taken straight from TIS... This is for AL 05-13 2nd gen Tacomas. The idiot at Eaton keep saying the newer Tacoma got bigger ring gears (06 and up in his eyes...)....see, a '05 Tacoma is 2nd gen, i.e NEWER Tacoma. 04 was the last year for the "early" Tacomas. :hmmmm2::motz:Note the ring gear size...
