If anyone can contribute to this in any way, that would be great! This is a complete guide to getting differential bearings for a lot cheaper than any of these other gear and bearing brands sell the kits at. In addition to this, the seals are from Toyota, which is a big deal for me. Also, this actually includes an output shaft bearing for the front differential which I have personally not seen in any "master rebuild" differential kit offered online.
This research results from a week long search into the best "master rebuild kit" online. What I finally figured out, the best option is to build your own master rebuild kit, and order from an online parts store. Personally, I always order from Conicelli Toyota Parts online parts store so these prices could be higher or lower depending on if you shop at a place like Camelback Toyota for instance. (I believe Conicelli and Camelback are the same with pricing.)
Feel free to add any additional differential, front end, or rear end drive-line component part numbers in this thread.
I WOULD LIKE TO NOTE: The rear differential breakdown is for an E-Locker 4Runner / Tacoma 8" 3rd member. If you do not have an E - Locker everything is the EXACT SAME besides the carrier bearings. You would order two of the "(small)" bearings. Not one (small) and one (big).
