hello, I have a 2004 Sequoia SR5 4x4 w/ about 160k miles on it. I just found out that the pinion bearing needs replaced, and it was recommended that I do the carrier bearings and possibly axle bearings while I'm at it. I trust the shop and he was willing to give me some help if I do it myself, or he said it would be $700-800 for them to do it. I am more than willing to try it myself, but things like crush sleeves (?) and back lash make me a little nervous. I did the timing belt myself with the help of alldatadiy, but they don't have any repair instructions on doing anything with the diff, other than prices. Can anyone recommend a site that would have detailed instructions on how to do this, or should I just suck it up and pay the mechanic?
Usually when I do a diy, it's my excuse to add some upgrades and fix other things with the money I am "saving." I abuse this thing as much as possible, and am always very impressed with some of the places it has taken me, and gotten me out of. I hunt with it frequently, and I pull a 16' double-axle trailer to either tow my 1972 Int'l Scout or load up with a cord or two of firewood. I'm thinking I need to upgrade my old suspension, possibly adding a small lift and trailer brake connection, and maybe even air bags. At the same time, it's my wife's family car when I'm not out beating on it, so I need to keep it wife-friendly (not too high, not extremely rough riding). Any suggestions? The airbags probably wouldn't be necessary, but I would like to get some feedback from others that have done similar things. Since I might have it taken apart in the garage for a while, this is probably the time to do some of this. Thanks for your help,
