Detailed Description

Suspensia X15LA0358 is a rear right upper control arm for Ford Escape and Mercury Mariner applications. It is manufactured in Turkey in IATF16949 certified factories, drawing on ISC Industries’ OE supply experience with major global vehicle manufacturers and Tier 1 programs. The arm uses steel for the housing and a rubber bushing design to support stable rear suspension movement, while the included ball joint arrives pre-greased for service-ready installation. This part cross-references MOOG Chassis Products RK621457 for the same application.

Common Problems This Part Can Address

• Excess rear suspension play from a worn upper control arm
• Clunking or knocking noises from the rear suspension
• Uneven rear tire wear caused by worn joint or bushing components
• Loose or unstable rear wheel control during driving
• Ball joint boot damage that can lead to joint contamination

Installation Notes and Tips

Compatible With 2001-2008 Ford Escape, rear right upper, and 2005-2008 Mercury Mariner, rear right upper. Verify the M12 x 1.25 stud thread size and 18 mm wrench size before installation. The ball joint uses a press-in mounting type and the arm is not greaseable, so service procedures should follow the vehicle’s rear suspension layout and alignment requirements after replacement. Castle nut and cotter pin are not included.
