LCWRGS Front Upper and Lower Ball Joints Replacement for Chevy SSR Trailblazer Ext Buick Rainier GMC Envoy XL XUV Ascender Bravada 9-7X K6663 K6664, 4pcs

The ball joints are alright. Not the best. If you are looking for something cheap to get you by for a bit these will work. The lower ball joint was a fight to get pressed in. I put my lower in the freezer for an hour before attempting install. Before I started the install I wire wheeled the lower control arm receiving hole. Then warmed up the control arm receiving hole with a map gas torch. Next put a small amount of general grease on the ball joint. Tapped the ball joint in a bit so it was square and began pressing. Even with all the precaution measures it still took a 3 foot 1/2" drive ratchet to crank it in with the press. Tightest ball joint fit I've ever dealt with and I've done alot. The original ball joint was 1.68" and these are 1.71" at room temp so slightly larger. Freezing brought it to 1.687".The top ball joint went right in with an electric impact gun. Takes 2 minutes to change. Seems like they aren't greased well from the factory so seeing how there is no fitting for grease I used a needle grease adapter under the bellow before install.

These lower ball joints don’t fit! Spent 8 hours trying to press them in and wouldn’t go past half way for anything. Put 1000 ft pound and wouldn’t budge. Went to Autozone and purchased new ones and those when right in. Lost a day of my life
