I'm reviving this old thread of mine, as a bit of rebuilding on the car is going to be going on. After our last trip up north, in April, the rear axle is giving up, old junk yard dog out of a Cressida wagon with unknown mileage. Did some looking at it over the weekend, while fixing other issues, broken door handles. Looks like the pinion bearings are shot, sounding a bit like a coffee grinder, which also means it's been chewing away at the ring and pinion teeth. Oh well, time to build a new axle. 3 years ago, when I started building this project, Cressidas were all over the yards, now it's been over a year since I saw a wagon, and the sedans I only see about every other trip. Back in the 80's, Toyota must have loved designing new axles, because it seems like very few vehicles have common axles in them. I've done some research and can't believe I didn't consider this new option before. The Vanwagon, predecessor to the Previa, has the F-code axle, like a light duty 2wd truck or the 1st gen Supra (also VERY rare). All the mounting brackets are wrong, but the spring perch seems to be in the right place, the width seems to be the same as the Cressida axle and what will save me the biggest headache, the lug pattern is still the 4x4.5". I was going to just buy a truck axle, but then that would have involved having the axles redrilled to the 4 lug pattern, drilling or coming up with new brakes, etc.. The first yard I checked at this weekend, had an online inventory, which said they got a Toyota van in about 5-6 weeks ago. I drove the 25 miles down there to find that the van was the rare version, 4wd, wrong parts again, 5 lug, but not the same as the pick-up. What a cool van though, I hear they even made a 5speed 4wd version, would make a great adventure van, if the parts weren't getting so hard to come by. The second yard I went to, first truck row I walked down, there it was, an '86, 5 speed (also kind of hard to come by), with an undamaged rear end. It took me about an hour to pull it out on my own, not bad, just bulky to lift onto the cart. This will be done the right way this time. All new bearings, all new seals, LSD from a 2nd gen Supra diff I have lying around (got it a few months ago), with Weir Performance goodies, like a sold pinion bearing spacer, instead of the factory crush sleeve, and the MaxGrip LSD kit to get more lock-up out of the diff. Both ring and pinion sets I have now are 4.10, which is what is currently in the car as well, so I'll probably just pick the one with the least amount of wear, likely the Supra, since it was behind an automatic, non-turbo drive-train.
