Hey guys, I just completed a drain and refill of the gear lube on each of the diffs and transfer case this weekend.

I assume I had LSD because of what appeared the be the remains of 2 factory stickers in the door jamb. 1 I assumed was the tell-tale orange sticker, but all that's left is a striped white adhesive residue.

I should have done the spin test while I had it jacked for the KYB replacement. Is this 100% accurate?

Short of jacking it again later this evening, is there another way to check? isnt there a build code somewhere on the radiator core support to say yes this has LSD?

And lastly... yes I did add the LSD additive. Am i hurting anything by having that stuff in there if it turns out to be a non-LSD diff?

Jim
