What It Helps Address

• Excessive play in the front left suspension
• Uneven tire wear caused by suspension looseness
• Steering wander or reduced directional stability
• Noise from deteriorated bushings or a damaged dust boot

Installation Notes

Fits 2008-2013 Cadillac CTS, front left upper; 2009-2011 Cadillac STS, front left upper; and 2004-2009 Cadillac SRX, front left upper. Verify the front left upper position and compare the original part number, stud thread size M12 x 1.75, and mounting style before installation. Because the ball joint is press-in and the assembly is pre-greased, installation should follow the vehicle service procedure and alignment should be checked after replacement.
