K6663 Front Lower Suspension Ball Joint for Chevrolet Trailblazer

These are adequate replacements for the OEM lower ball joints. The OEM lower ball joints are glued in so it may be necessary to heat them up a bit before pressing them out.The new MOOG joints have raised grooves that bite into the lower control arm, eliminating the need for glue and retained with a clip. The grooves do mate the internal surface a bit but subsequent replacements shouldn’t affect fitment if one needed to replace a MOOG with another MOOG ball joint.Installation was straightforward, if replacing OEM, use some heat to break down the glue used at the factory, otherwise press the old joint out and press the new one in. You may need specialty press adapters to fit on the ears of the lower control arm.Add the included grease zerk and add grease, making sure each zerk faces the front of the vehicle for easier re-greasing when installed.The hardware included lets you install a new castle nut and cotter pin so no need to reuse the old.Overall it’s a great value compared to OEM and I am very happy with the result.

Boots stay in place , unlike the top ball joints . Seems well made

Easy install . Didn't have to worry about damaging the boot while pressing it in.

A name to trust. Easy instalation

I especially like that these have grease fitting for regular maintenance.

Heavy duty brand name at a great price

Fit my 2003 Trailblazer EXT perfectly. Great price. Just be prepared to fill ball joint with grease as it does not have much in it.

I have never had a faulty unit yet , and if worn in 3,4,5 yrs never had an issue with replacement (you just pay to reinstall) .

Fit like original. Great replacement for my 2008 Trailblazer.

Seems fine. I ordered two ball joints and they were slightly different as it looks like they did a product update / change and one was new stock and other was old. I sure don't like that sort of thing cause it seems sketchy but at the end of the day the fitup was the same and they work.
