2008 Vert Differntial Issue?

[gwingard81]

Hello all. I've had my viper for a couple years. Mileage is currently at 17k, 12k of those over the past two years. I've noticed some grinding and vibration/rumbling when taking tight turns while in gear at slow speeds. No issues when taking tight turns when not in gear. I've changed the differential fluid and there was no metal present. I'm guessing this isn't normal. Any ideas?

Thank you.

Did you add the Diff additive?

I used mobil 1 75w 140 w/ limited slip modifier included. The issue was present before I changed the diff fluid.

I would first check the half shafts u-joints / bolts and wheal bearings.

Ok. Will do. Thank you.

I'd suggest trying a different fluid, specifically this one:

It's the relabeled version of what used to be Castrol SAF-XJ.

Does it do it all the time regardless of outside temperature or component temperature? I know mine will make some pretty gnarly crunching noises when it's super cold outside and I'm navigating parking lots or something like that for instance, but it will go away pretty quickly once I've gone any kind of distance and got things moving. And when I say cold, I mean like, 30 degree and below kind of cold that most people don't drive their Vipers in, so probably not that common, but it came to mind.
