Year of Manufacture *: 2012 Engine Size and Code *: 2.0 ( Optional) Fault Codes: None
Juddering & knocking during accleration at rear of vehicle? Suspect sticking handbrake mechanisim in drum assembly! Nothing found all o.k! & all 4 wheels rotate with ease.
Are all four tyres the same size/make and type. Tread depth should be no more than 2mm difference (front to rear), with deeper tread on the rear. If tyres are different, measure circumference at centre of the tyres. Should be the same +/- 10mm.
Any fault codes in 4wd system? Check the wiring above the differential, they're prone to rubbing through onto the diff/subframe. This has the effect of pulling the clutch pack in all the time.
If you unplug the rear diff control connector, does the shuddering stop? If not = clutch packs are shot. If so, more likely 4wd system fault.
