Front Hydrobearing Bushing (FCAB), Lemforder - E83 X3 2.5/3.0/3.0si
OEM rubber bushing to restore original ride comfort and steering precision. Replacement for BMW part #31103412781
This is the OEM Lemforder hydrobearing bushing for the front tension struts on the E83 X3 models. The tension strut is also known as the thrust arm and is the forward-most control arm on the E83 X3 chassis. The bushing is filled with a vibration-absorbing fluid that does a great job of isolating bumps and rough roads, until the fluid leaks or evaporates. Worn X3 bushings will affect the ride, handling, and steering of the car and can also cause clunking noises and vibrations. To restore steering precision and taught handling, replace the tension strut bushing at the first sign of wear.
This is a pair of OEM bushings (hydrobearing) for the tension strut / thrust arm, made by Lemforder or TRW, original suppliers to BMW of this part and many other suspension components on your car. It comes with a two year warranty.
Powerflex urethane replacement bushings are also available (see below).
