Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC9129
Delphi TC6006 front left upper control arm with ball joint for the 2015 Infiniti Q40 and other vehicles connects the wheel knuckle to the vehicle body and gives the wheel a pivot at the joint. It is sold as a control arm and ball joint assembly, so the arm and the joint are changed as one piece.
A clunk over bumps or uneven front tire wear can point to a worn arm or ball joint, but a tie rod end or a sway bar link may be behind the same signs, so find the cause first. This listing is one arm for the front left; the 2015 Infiniti Q40 takes one on that side, the front right upper is ordered separately, and the two are normally replaced together.
This arm is listed for a wide range of Infiniti models, with the 2009-2013 Infiniti G37 and the 2011-2012 Infiniti G25 among the top ones.
