Welding the differential???
 

hey guys i just wanna know what exactly does welding or shimming the differential do? Does it make it to where both wheels spin as opposed to just the one that does on ours? any help is appreciated

and how much work is involved in doing that process assuming i knew how to weld? thanks in advance

ps. this may have more hits in the drift category, wasnt sure.

You DO NOT want to weld your spider gears in the differential.
If you did (and I have done it before, on 4x4 mud puller trucks), you could NOT drive the car on pavement.

Shimming is for LSD diff. It make it tighter than stock, but not good for a daily driver car. And, a bunch of work that you, or whomever does it, better know what they are doing.

Get an LSD diff out of a mk3 turbo supra. All turbo supras came with an LSD. N/A's didn't.

would that explain why sometimes only my right rear wheel will spin, as oppose to both?

Yep, but unless you won't drive ur car on the street anymore, don't weld it, next thing that you're gonna break is an axle,
Jus get the diff from a turbo mk3

Ah i see, thanks for the input. So turbos have LSD and N/A's do not, i was unaware of that.. good to know

I had an NA with lsd, I only said look for a turbo mk3 since your more likely to find an lsd on a turbo one rather the na

oh, so now how would you depict the two?

the easiest way to find out if a car has lsd without opening anything
is to put the rearend on jacks and spin the tires if the other one spins to the same direction as the other one, then it has a lsd

so do all mk3 models have lsd ? i know u might not agree witha welded diff, but i have been told haveing a welded diff may help me drift better. and driveing on the streets no prob. i see nissan 240's use them as a daily and drift.
