Detailed Description

The Suspensia X15LA0359 rear left upper control arm is engineered for the rear suspension on Ford Escape and Mercury Mariner models listed above. It is a practical replacement for worn or damaged upper control arm assemblies that can affect rear wheel positioning, ride quality, and suspension noise. This part cross-references MOOG Chassis Products RK622126 for the same application. Suspensia is manufactured in Turkey in IATF 16949 certified factories, with production backed by ISC Industries’ OE supply experience for major global vehicle manufacturers.

What It Helps Address

• Rear suspension clunking or looseness from worn control arm joints
• Uneven rear tire wear caused by suspension geometry changes
• Excess movement in the rear left upper suspension link
• Alignment issues related to a deteriorated control arm assembly
• Noise or vibration from aging rubber bushings or ball joint wear

Installation Notes and Tips

Verify the rear left upper position before installation and confirm M12 x 1.25 stud thread size and 18 mm wrench size during service. Because the ball joint is press-in and the assembly is pre-greased, no grease fitting is provided. Inspect adjacent rear suspension components and perform a wheel alignment after replacement on the Ford Escape or Mercury Mariner.
