BMW i3 Front Lower Control Arm
This BMW i3 front lower control arm locates the wheel and lets it move up and down with the suspension, while its bushes absorb road shocks and keep the wheel at the correct angle. Electric cars carry extra weight from their batteries, so suspension arms and their bushes work hard. This front control arm locates the front wheel on the BMW i3 and carries the suspension loads between the hub and the body. It is made from aluminium and comes with the bushes and ball joint already fitted.
Specifications at a glance: material aluminium, cone size 19 mm, outside thread M16 x 1.5 and supplied with Bushes and ball joint.
Signs Your Front Lower Control Arm Needs Replacing
Signs of a worn control arm or bush include a clunk over bumps or when braking, vague steering, pulling to one side and uneven tyre wear. Split bushes and play in the joints are common MOT advisories. Catching these signs early usually means a simpler and cheaper repair. Electric cars are heavy and very quiet, so worn parts are often noticed sooner than on a petrol car.

Fitting Advice
Tighten the bush bolts with the suspension at its normal ride height so the bushes are not preloaded, and have a wheel alignment done after fitting. Please if the vehicle is equipped with driver assistance systems, a sensor calibration may be necessary. Replacing arms on both sides keeps the handling balanced. Check the anti-roll bar links at the same time.
