TIP: Replace the entire arm (ball joint on one end and the big bushing on the other end). If the OE one lasted XXXX miles than you can expect the replacement to do the same. If you are looking for improvement in handling, then look into Meyle HD arms or go the Poly bushing as recommended earlier. RUN from no name China parts, as you get to be the "tester" and quality control department. Buy a brand that has some quality control to it's name, Meyle, Lemforder, BMW (reboxes other brands as "BMW").
Most owners replace / upgrade all the moving suspension parts at this 10 year++ mark. That way it a one time overhaul and done.
Kits are available: From FCP EURO
https://www.fcpeuro.com/BMW-parts/X5...0&m=228&page=1 Don't forget to Replace the Sway Bar links at the same time.
Depending on your driving habits (First off at every light, last minute braking, wide open driveway apron hits, etc, then your suspension parts will need replacements/attention every 40K as the individual parts fail.
