Have a 87' Corolla GT-S with LSD.

R&P Gears are shot and got quoted $700 bucks for a rebuild from a very reputable shop. $1000 from a company that actually manufactures rear end parts. Almost the price of the car when I bought it.

Was wondering if a guy(me) with some mechanical knowledge, service manual, and tools can get it done correctly.

And anyone in So-Cal want to walk me through? I'll bring the beers and pizza!

$700 for a comlete rebuild in the car is a deal, IMO.

$1000 sounds more normal.

There are instructionals on Youtube that will make this a cakewalk, but parts will probably cost at least $300.

With the youtube instructionals, you'd recommend me just go for it huh?

Would you have the links to the one your talking about?

I'll go search right now. Thanks

If you buy a OEM gearset, it will likely save you a lot of trouble because you can reuse the factory shims and just worry about the crush sleeve.

Another option, find a whole rear end in a salvage yard and swap it out.

Setting up a rear end for the first time by yourself is not advisable. By the time you factor in all the cost of gears and bearings, the extra tools you need etc do you want to pay to do it twice if you do it wrong? I'd get a used one like White said and swap it in. For the trucks you can get the get just the third for $75 and the whole axle for $150 not sure on the toy car stuff. Another option, see if toyota has the thirds on the shelf if you can't find one at a wrecker.

I removed the pumpkin from the axle housing and had it inspected by a 4x4 shop owner and he told me the ring and pinion was shot. Parts $450 he charges $250 for labor. He recommended me to find a pumpkin from the salvage yard and swap out. He even went ahead and called a salvage yard guy and I guess these guys have a network where they can look for parts in different yards.

Well, they couldn't find my rear. 87' is the last year for my body style and 87 is the only year they came with larger axles. It's also a GTS so it has a totally different casing than the SR-5s and it's factory optioned LSD so the gear set is a special kind from what I'm told.

Parts are on order and as of right now, I've decided to rebuild it myself. I have access to tools and waiting on parts right now. I know I should have bought new gears but I bought some good condition used pieces.

Any advice before I start?

Well since you've decided to go for it read all these to get an idea with the toyota stuff.

Setting pinion depth will be the hard part, and that's not even really hard if you have a dial indicator.

Again, if you use factory parts then you'll probably be able to use the same shims and it will be perfect.

Right on, I bought a assembly kit that came with bearings, shims, ring gear bolts, gasket, etc. So I think I have parts taken care of.

Got all the specs for pre-load, backlash, and ring gear run out. All readings were waaayyy off spec. Sitting in a box waiting for assembly, I'm getting help from another tech and he's a busy guy so I'll probably have it done by the end of next week. Can't wait to get it back in the car.
