Front Left Tension Strut, OEM - E83 X3
OEM driver side tension strut / thrust arm with stock rubber bushing
This is the OEM front left tension strut for the 2003-2010 E83 X3 models. The tension strut is also known as the thrust arm and is the forward-most control arm on the E83 chassis. The arm includes the inner hydrobearing bushing (but not the outer ball joint). 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 complete tension strut at the first sign of wear.
This is an OEM tension strut manufactured by TRW - an original supplier to BMW for many other arms and bushings. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
Powerflex urethane replacement inner bushings are also available (see below).
The outer ball joint attached to this arm is sold separately. See below for the OEM ball joint.
