The lower control arm carries the majority of the suspension's vertical and cornering load, and its bushings and ball joint are among the highest-wear items on any European car. The symptom sequence is consistent: a knock over expansion joints and speed bumps, then imprecise steering on centre, then inner-edge tyre wear that is routinely misdiagnosed as an alignment problem.
We supply genuine OEM lower control arms complete with bushings and ball joints across every marque we serve. Send us your VIN and we will confirm before you order — front and rear, left and right are frequently four distinct part numbers.
Replace the arm, not the bushing. Most European manufacturers supply the arm complete with bushing and ball joint pressed in, and that is the intended repair. Pressing a new bushing into a worn arm reintroduces the fault within months and wastes the labour.
Replace in pairs where load is shared. A new arm working alongside a worn one on the same axle takes disproportionate load. On platforms carrying multiple arms per corner — the Audi B8, B9, C7 and C8 among them — replacing the affected side as a set is the durable approach.
Alignment is mandatory afterwards. A four-wheel alignment is required after disturbing any control arm. Skipping it converts a correct repair into premature tyre wear.
Calendar age matters. Rubber bushings degrade with heat and time as well as mileage. Low-mileage cars in Gulf conditions still need inspection on a calendar basis.
Seized bolts are the real job risk. Control arm through-bolts corrode into their bushing sleeves and are a common cause of a straightforward job becoming a difficult one. Plan for it.

My car knocks over bumps — is it the control arm? Most often the lower arm bushing or a stabiliser link. Both are inexpensive relative to the tyre wear they cause if left unaddressed.
Can I replace just the bushing? Usually not as intended. Most European arms are supplied complete, and that is the durable repair.
The new arm's bolts won't line up. A common and fixable situation, usually down to suspension position under load rather than a wrong part. Read our guide on control arm bolt alignment →
Do I need an alignment afterwards? Yes, always. Any disturbed arm changes camber and toe.
