Detailed Description

This Dorman suspension ball joint, part number 540-011, is precision-engineered and tested for reliable OE-style replacement on the rear lower rearward suspension position. It is built from steel and uses a threaded design with a tapered stud, making it a direct service part for the rear suspension on Ford Expedition and Lincoln Navigator applications. The rubber dust boot helps protect the joint from road debris and moisture, while the standard replacement construction supports consistent suspension articulation.

This part cross-references MOOG Chassis Products (e.g., K500166) for the same application. If you are replacing a worn rear suspension ball joint on a Ford Expedition or Lincoln Navigator, Dorman 540-011 provides a focused fitment for the specified rear lower rearward position.

What It Helps Address

• Clunking or popping noises from the rear suspension
• Excessive play in the rear lower rearward suspension joint
• Uneven rear suspension movement over bumps and road joints
• Steering or handling looseness caused by worn suspension linkage
• Dust and moisture intrusion into a damaged ball joint boot

Installation Notes and Tips

Confirm the rear lower rearward position before installation on the Ford Expedition or Lincoln Navigator. The press-in mounting type requires proper suspension service tools and careful alignment during installation. Verify stud thread length, wrench size, and mounting dimensions against the removed part before final assembly. Because this is a threaded ball joint design, inspect the surrounding control arm and related hardware for wear before reassembly.

Quality Assurance

Dorman manufactures this part as a tested replacement for the original equipment application. Part number 540-011 is built to meet standard suspension service requirements for the listed Ford Expedition and Lincoln Navigator fitments.
