the best thing is to jack it up as high as you can then put jack stands under it on the frame rails. NOT THE REAR SUBFRAME MOUNTING POINTS!!!! that will cause the subframe to tilt and be a pita to reinstall. btdt.



remove the 4 nuts holding each half shaft to the diff.(14mm)



then remove the 4 nuts and bolts that are holding the drive shaft to the diff.(12mm)



then remove the 2 19mm nuts that are facing the rear of the car just above the sway bar. leave the 2 bolts in the holes to hold the diff when you remove the other bolts.


now remove the 4 17mm bolts from the top of the diff., then remove the 4 17mm bolts on the sides of the diff.(2 on each side)


once all bolts are removed, put a jack under the diff., leave about 1in between them. pull the 2 bolts that had the 19mm nuts on them out. you will probably have to smack it with a wrench. once it jars free, lower the jack and pull it out.

for reinstallation, place it on a jack and roll it underneath lined up as best you can. jack it up into place. if it seems to catch, keep jacking it up SLOWLY, it will pop into place, once it does, be sure those 2 bolts on top line up first(the large 19mm bolts) and slide the bolts through. you may have to hit it to knock it one way or the other, you may also have to slightly lower the jack.



once you slide those in, lower the jack from the diff and place it under the nose of the diff. slowly jack up the nose of the diff until the front side bolts line up.


then put the 4 17mm bolts in on the sides. once screwed almost all the way in (DO NOT TIGHEN THEM YET) try putting in the 4 top 17mm bolts if they dont quite line up, try raising the nose slightly, they should line up.


once those 4 bolts are threaded in, tighten all 8 of the 17mm bolts, then tighten the 2 19mm nuts onto the bolts coming through the top rear.


then bolt the drive shaft and half shafts back on(preferably with new lock washers).



then jack the car back up and remove the jack stands, lower the car. guess what, your fininshed.

uhh

two differential types available
limited slip = 2 wheels spin
open = only one wheel turns


Now that you know that much, your 83 P type Supra should have a 4.10 limited slip differential with 7.5" ring gear. Your best bet would be to go to a junkyard, as these babies cost $1,300 new from Toyota (last I heard)

You will need to look at the donor cars data plate under the hood to find out what gear ratio it has, you should be loooking for a F293

i have a 84 l type (i think) and i put a new LSD in it out of u-pull-ti last year. the car i got it out of had not motor, tranny, dash, flares, hardly anything so i dont know what type it was and i couldnt tell the year other then a MKII. how cant i check what ratio my LSD is? is it printed somewhere (other then the engine bay of the donor car) or do i need part numbers?

Did you happen to count the teeth on both the ring and pinion gears? If not, spinning the pinion around until the axle hub makes one complet revolution works also.

non LSD=LSD? ~^~

Can the spider gears be shimmed to make it not so non-lsd?I wanna change the diff oil to synthetic and clean up the cover and replace the gasket and as long as I was in there...

only thing you can do to a non lsd diff to make it lock is to weld it, which isnt recomended at all. your turning radius will completely suck and the car wont handle properly.

non lsd

Never had one apart. Is it like a GM or Ford diff that has the spiders held in with a pin?

hey does anyone know what i have to replace cuz whenever i shift to D or R, it makes a metal noise, also when the tranny is downshifting, sounds like it was coming from the LSD, do u guys think that i should replace the pinion and ring , cuz it sounds like it has some play in the gears. BTW this is an automatic mk2 celicasupra. thanks...

Are you sure about the 3 quarts there Armin?? I thought the fluid capacity was 1.3 L? Roughly 1.4 Quarts. I use Amsoil 75W90 diff fluid.

I know it's either just under 2qts or just under 3 qts, but it never hurts to have extra ;)

No, it doesn't hurt to have extra....but that extra will end up spewing out the breather and coating the underside of the car!! :D Ask me how I know...my mechanic put in a full two quarts!!...after I gave him the diff sheets from the TSRM!! Oh well....no harm done...just a bloody mess!!
