I've been sort of a lurker here for awhile, since my supra has been garaged several thousand miles away for the past couple years. Of course, family took good care of it while I was gone, and drove it around once a week to make sure it didn't rot. I just recently had it shipped out here to California, thinking I might as well have a joyride while living on the beautiful central coast.

As luck would have it, within the first week my rear end started making horrible noises. I suspected the differential. I brought it into a shop, and upon opening the differential casing, they found that it was pretty much hosed. Apparently it was bone dry, no oil in it at all. There wasn't any leaking, so best guess is that the last guy to do work on the car drained the oil, and never filled it back up again. Great.

The problem is, the guy at the shop can't find a replacement differential anywhere. The part is discontinued, and apparently there isn't much of a market for used supra parts in the area. He's found a differential with a 4.10 ratio, but my supra had a 3.73 ratio; he COULD replace it with the 4.10, but it would get much more costly since he would need to swap out some of the gearing.

My question is: where do you California guys go when you need replacement supra parts? I'm pretty new to the area, so I'm not sure whats available along the lines of Supra shops, junkyards, and whatnot, especially along the Central Coast. All the new differentials I've seen online go for a minimum of $900, and I'd rather not drop a grand on just the parts, when I still need to pay for labor too.

Any suggestions/recommendations would be appreciated.

Your best bet is to find someone who is parting out a car so you can know if the differential is any good. Next best thing is to call around to different wrecking yards to locate one. I wouldnt pay any more than $200 for an extremely nice one. Probably $150 for something between 100,000-150,000 miles. Anything more than that and there is a good chance that the clutch packs are bad or going bad.

Hmm, prices I've been quoted have been between $400-$600 for a used one... That's no where near the $150-$200 max you recommended.

Are there any supra shops in Norcal or Socal that would carry used differentials?

if you were on the east coast i would hook you up with a 373.there's also a 390 rear in a pic your parts yard($75 all you can carry).one hour at the most with basic tools to pull one.

That`s a lot for a rear end. I know of 2 4.30 lsd here in the Houston area, $100 and he`ll have it pulled and waiting for me. To bad you`re not closer, I have 3.93 (87-88?) in my parts car.

Well, the guy at the shop found one from somewhere. It's the entire differential housing, including the differential, ring gear, all that jazz; correct 3.73 ratio as well. Problem is that its $600, used, but apparently includes a warranty. This seems like a pretty ridiculous amount, but I'd rather pay $600 plus the labor to just swap out the unit rather than pay for a full rebuild, which would be like $1800 after all the parts and labor.

Any idea why this would be this expensive? Is it because of the warranty? Or because it includes the housing and everything?

Everyone here is talking about the housing and ring & pinion, etc. Nobody really sells just the diff itself, and if they did, they wouldn't talk about gearing, since that's seperate.

As for labor, I guess you've already got it at the shop, but changing out a diff in a MK3 is like an hour's worth of work, I wouldn't pay a shop to do that.

A brand new differential (housing, ring & pinion, stubs, all assembled, etc) is just under $1600 from Toyota, say with shop time of 2 hours even, that's still under $1800 for a completely brand new setup.

There are TONS of Supra guys in Cali. Find someone with a parts car and grab the diff. I'm sure you can find one for under $200 easily. Good luck.
