The pressed-in cover plate seals out debris and helps minimize looseness. If a worn front upper ball joint is behind your steering play or clunk, this MOOG unit is designed to restore fit and function on the listed applications.
What is the MOOG K6540 and where does it mount?
It's a front upper suspension ball joint that pivots the steering knuckle and helps locate the front suspension. It installs in the front upper position on the listed GM trucks and SUVs.
Does this ball joint fit my vehicle?
It's a direct-fit replacement for applications like the 1999-2006 Silverado 1500/Sierra 1500, 2000-2006 Tahoe/Yukon/Suburban 1500 and 2002-2006 Escalade. Check the Buyer's Guide tab to confirm your year, make and model.
Is the K6540 greaseable?
Yes. It has a greaseable socket, so adding new lubricant flushes out contaminants to help reduce corrosion and wear over service intervals.
What are the signs my ball joint may need replacing?
Common signs include steering play, a clunk from the front end, uneven tire wear or looseness in the joint. Diagnose the cause before replacing, since other parts can produce similar symptoms.
Should I replace both front upper ball joints at once?
Replacing the matching joint on the other side at the same time is a good practice for balanced steering and even wear, though this listing is for one ball joint.
