Mevotech TTX Suspension Control Arm and Ball Joint Assembly P/N:CTXMS401270
Mevotech TTX CTXMS501179 front left lower control arm with ball joint for the 2011-2019 Chevrolet Silverado 2500 HD and other vehicles links the wheel to the frame and lets it pivot. This control arm and ball joint assembly replaces the arm, ball joint and bushings in one piece.
A clunk over bumps, uneven tire wear or loose steering can mean the arm, ball joint or bushings are worn. These signs alone do not prove this part is the problem; a worn shock or strut can cause a similar clunk. Front lower arms are normally replaced as a pair, and this listing is one; the front right is ordered separately.
The 2011-2019 Chevrolet Silverado 2500 HD, the 2011-2019 Chevrolet Silverado 3500 HD and the 2011-2019 GMC Sierra 2500 HD take this front left lower control arm, along with other vehicles, and each takes one on that side.
