Review on 🔧 Enhanced MOOG RK620291 Control Arm with Ball Joint Assembly for Improved Performance by Chris Horton

So all in all a decent control lever. I ordered a replacement set for my Buick Lesabre 02 and they fit perfectly. The problem arose when I installed the Zerk fitting. I inserted the armature by hand and it kept turning. I suspect the hole was drilled too big because the fitting could just pull out so the threads don't really grab. Unfortunately, I had to let that go and just lubricate the joint as best I could. You surely know that without this fitting, grease will leak out of the ball joint and an unlubricated ball joint will fail. I'll try to fix it in the next day or two. I am very disappointed with the workmanship of this part and will consider another supplier in the future. It's a shame because I've always been a pretty loyal MOOG customer.
