SC 300 Rear Differential issues

[ahmed]

ok im making about 500hp wheel in my sc300..

im on stock w58 and stock rear end. rear end has 210k on it. today after doin many pulls and spinning tires till 90mph it wheel hopped pretty bad. the diff is gettin weak. still drives mint but when commin to a slow stop it sounds like teeth skipping..


my question is what rear ends will be a direct swap with no axel changes or driveshaft changes i dont care is the gearing is the same or not. the shorter the better... need something crazy cheap and fast.

this is a 1992 sc300 5 speed..

did you try looking at junked sc300's? there are lots of them heh

Pretty sure TT auto diffs are direct swap. Figure out your wheel hop problem or you'll continue to break parts.

it never wheel hopped before. found one is a local yard. what fluid should i use.

 

[tlo86]

long pulls (highway etc) can kill it. dont remember what it called for, 75w90? redline? and the trans is straight 90? for the r154 and w58

i was told gm syncromesh for the trans w58 and royal purple for the rear end
