Jetta rear axle

All Jetta vehicles are fitted with an anti-roll bar
18 mm dia. for vehicles with 1.3 and 1.5 l engines.
20.5 mm dia. for vehicles with 1.6 l engines (GLI).

The bonded rubber bushes in the brackets for the rear axle suspension have a greater shore hardness compared to the brackets for the Golf/Scirocco. To avoid noise, the brackets must not be interchanged.
