Differntial problem concerning my new m50 swap

[socalife]

So I just got the car, and it formally had a 4 cylinder engine on it with a 4.1 open differntial. You know since I just got the car, I've been stepping on the gas and redlining but all of a sudden I hear gear whine in 1st gear and whine throughout the higher rpms. Also, I get a loud click everytime I step on the gas. Do I need to change it?

[SkiFree]

It's very likely.

I would say she is smoked.

168mm Diffs dont like abuse or power..

[socalife]

What about the clunking noise from the back when I step on gas

[nando]

That would be your small case diff crying for mercy.

[shocwav3]

Driveshaft bolts in the rear are tight? U joint have any slop?

[THEhomelessONE]

Lol your car's bitchin for some LSD

[sam_]

Those diffs won't take any abuse.

[Jib05]

Destroyed my small case diff with a 2l m20. Change le diff.

[SkiFree]

I'll disagree....... 168's are good with mild abuse up to 230-ish. If you're bustin it before then, then you've been neglecting the case and something other than simple "too much power" is/was the root of your trouble.

Have you checked your transmission / differential fluids?

Perhaps put a piece of cardboard under the car when u park and see if anything is leaking; If you are low on fluid for either it will be whiny
