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

HI,

Most 240sx’s come equipped with what is called an open differential. An open differential is designed with four gears set inside a casing that is rotated by the driveshaft. One gear connects to each output shaft and the remaining two gears connect to a center pinion and rotate in opposite directions perpendicular to the rotation of the casing.
In this manner, power can only be sent to one wheel at a time because the pinion gears counter the rotation of the casing for one output shaft at a time. In short, one wheel gets power while the other one coasts.


Thank you....
