I have a 92 sc300 with a 1jz gte.. w58.. few upgrades.. anyways my right rear driverside wheel sounds like it is breaking when i turn and its wobbling.. when i go straight its fine.. the shop said my rear end is bad but im going to take it to get a 2nd opinion tomorrow.. lets say its bad i cant find a auto supra diff. but what i can find is a sc300 replacement and some sc400 ones.. ok my ? is does anyone know what could be wrong with the rear end not liking to turn corners and how would i know the rear end is out of a sc300 auto or manual.. i know all about the ratios so is there something on the rear diff like a mark or something so i know that im getn a manual one and not a auto one.. or should i go with the auto one..n also my car is on here some guy was trying to sell it lol key words sc300 departure exhaust.. it looks better know i put new headlightts and tinted my brights and my marker lights.. i found it on her tonight when i was trying to find stuff.. someone said the exhaust was like 1 of 2 in the country.. lol i almost threw it away bc it made my car sound like a plane..lol any input would be great..

 

i have been searching all night.. cant find some ? i have.. will a sc400 rear end work.. also i jacked my car up and was turning my back wheels and i would turn my wheel trying to hear a sound and after half of turn i hear a clunk and then both of my tires would spin the same way so i dont know if it has a aftermarket lsd rear end or it is one of the rare ones that came with lsd( which 9 out of 10 people say doesnt exist).. is there a some way to know exactly what kind of rear end i have.. like a code or mark on them.. i can leave two marks onthe ground but sometimes around corners it goes from one wheel to both just like any mustang iv had but sometimes it spins both around corners too.. it could of been upgraded from past owners and i would spend the money to fix it if i knew it was a lsd.. some help will be much appreciated.. hopefully i posted this in the rite place.. thanks

Could be your wheel alignment too.

 

Sounds like the rear diff spider /bevel gears are to blame so yea you would need a new diff and no lsd ever came on our cars.
SC400 diff will bolt in but gear ratio would be off as well as the spedo.
