What This Part Helps Address

• Front-end looseness or wandering caused by worn control arm bushings
• Clunking or popping from a worn lower ball joint
• Uneven tire wear related to suspension geometry issues
• Steering instability on Ford Escape and Mercury Mariner front right lower suspension
• Excess movement in the lower control arm assembly

Installation Notes and Tips

Verify the front right lower position before installation and confirm stud thread size M12 x 1.25 and ball joint thread diameter 12 mm during service. The ball joint uses a press-in mounting type and includes a threaded stud, so proper suspension tools and alignment procedures are recommended after installation. Because the assembly is pre-greased and not greaseable, no grease fitting service is required.
