What It Helps Fix

Installation Notes and Tips

Fits 2006-2010 Jeep Commander, front upper. Fits 2005-2010 Jeep Grand Cherokee, front upper. Verify the tapered stud, threaded design, and 12 mm wrench size before installation. Because this is a press-in style suspension component, proper removal and installation tools are recommended, and a wheel alignment should be performed after service to confirm caster and camber settings.
