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 don´t 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 doesn´t have Quadra Drive, then have a look at the fluid level in the T-case.
