Detailed Description

What This Part Helps Address

• Front-end looseness or wandering caused by worn suspension joints
• Clunking or knocking from a deteriorated lower control arm assembly
• Uneven tire wear related to suspension geometry changes
• Reduced steering precision on Lexus RX and Toyota Sienna platforms
• Ride quality loss from worn bushings or ball joint wear

Installation Notes

Install in the front right lower suspension position only. Verify vehicle year, make, model, and trim before ordering, especially on Lexus RX and TX variants and Toyota Sienna applications. Because this assembly includes a bolt-in ball joint with threaded stud, castle nut, cotter pin, and mounting hardware where required, installation is streamlined compared with sourcing separate service parts. A professional alignment is recommended after replacement.
