- Fits: 2011-2013 Ram 2500 and other vehicles

A clunk over bumps, loose or wandering steering or uneven tire wear can mean a worn control arm bushing or ball joint. A worn tie rod end is another common source of such noises and looseness, so these signs alone do not prove this arm is at fault. Replace both sides together; this listing is one arm.
Fits
The 2011-2013 Ram 2500, the 2006-2010 Dodge Ram 2500 and the 2006-2008 Dodge Ram 1500 fit this arm along with many other trucks, and each takes two.
