Review on Moog K80997 Ball Joint by Larkeese Casiano

They fit my 2009 Z71 Colorado exactly, changed the top at the same time, big difference (better) in handling, brakes, everything. The truck only has 42,000 miles, but it's a V8 4x4, the stock ball joints are pretty tired. You will need to loosen the axle drive nut and slide the axle toward the center of the car to loosen the lower ball joint. You may need to use a brass drift or large puller, which again is just enough to free the lower ball joint. DO NOT completely remove the axle from the hub. I plan to replace all chassis/suspension parts with Moog, I'm impressed.
