Yesterday i flushed & refilled my VX's differential fluids,the rear had a lil leak & the pinion seal were replaced. I did it because the VX LSD developed a kind of kicking behavior,ever time i make a full stop the differential behaved like the following car just slight tapped your bumper,thought something was going wrong with the differential assemble.

The mech checked the differential for potential damage,hopefully any was found.Said the old fluids were very clean & still with a high concentrated viscosity level.

I add the castroil full synthetic 75w-90 (black color bottle) with a bottle of LSD addditive by CRC industries which meets GM's LSD requirements called K&W,very happy with the outcome

Though i can share this one with guys,specially if any of you are'bout to do the same.

Have good one guys
