Gts4 Rear Diff Clunking On Turns

[RIPae86]

Long story short. I just happened to change diff oil to some redlin 75w90 and now it makes a clunking rumble when I turn sharply. When it warms up it's less aggressive but still noticeable. I thought it was rear alignment but after getting that done it's still there.

Anyone have any thoughts of what this could be?

Just the dif locking as you turn.

Try a more slippery dif fluid.

Is it damaging in any way for daily use? I see a lot of gtrs use redline or similar.

as long as its recomended for LSD use its fine, it also can be your clutch pack binding which isnt a bad thing other than the noise. almost makes a locker out of an lsd. my diff the lsd is so packed up it skips the inside wheel on turns just like a locker, its good to know that your diff isnt suddenly going to crack open wheel out of a corner.

Thanks for the info. It's standard as far as I know.

I'm using 75w90 gl-5

Anyways it should be alright. I'll try to find the right spec and give that a try for daily use and save this for track days
