Most 1996 - on Audi models have a sophisticated multi-link front control arm suspension. The Audi S4 struts are mounted onto the control arm and the integral Audi S4 control arm ball joint is at an upside down installation position.

The weight of an Audi S4 chassis rests on the upper side of the control arm ball joint. Such significant dynamic loads can lead to eventual failure of the control arm bushings hydro filling. Too, due to the force of gravity, the lubricant in the control arm ball joint flows from the upper side downwards into the sealing ring. This loss of lubrication leads to wear and eventual failure of the integral Audi S4 control arm ball joint. Audi S4 owners become aware of this by the front suspension squeaking noise when braking.

Ocap control arm kits are a great replacement option. Ocap of Italy has improved Audi S4 control arms.
