Does anyone have any advice? The wheels are stock and fitted with Pirelli Scorpions.
Thanks in advance.
Welcome to the garage.
You most probably have a Quadra Drive jeep? This behaviour happens normally on this type of jeep due to a too low amount of friction modifier in the diff. The friction modifier (also called limited slip additive) is there to allow a small amount of slip in the vari-Lock diff, which is necessary when making turns (inner wheel travels less then outer wheel, so a totally locked diff would cause a wheel to skip). You could just add the modifier, or when you donīt know the service history, just change the diff fluid and add the modifier.
0.07l or 2.5 oz. of friction modifier needed per diff.
If you jeep doesnīt have Quadra Drive, then have a look at the fluid level in the T-case.
