Worn control arm bushings can cause excessive front tire wear, popping or creaking in the front end, extra play in the steering system, and pose a serious safety concern. Replace that heavily rusted, rotted, or damaged front lower control arm with the loose bushings with our high quality all in one replacement.

Our control arms are designed to be direct replacements for the original factory parts.  They are 100% brand new and require no modifications for installation.  No special tools are required because all of the bushings come pre-installed.

Lower Control arms- complete
I ordered lower control arms that include bushings and ball joints; they arrived sooner than scheduled and were a perfect fit. This resolved the sway and looseness in the front end of my car at a great price.

Its better to replace the whole part then just the ball more noise.
