Review on Enhance Vehicle Performance with the MOOG RK620380 Control Arm and Ball Joint Assembly by Miro Dadee

I had the same problem as Steve. The ball joint did not absorb grease as expected. Although there was probably enough lubrication at the top for the ball joint to work properly, no lubrication got to the boot area. Without lubrication, the dust boot would not seat properly on the steering knuckle (and would eventually break apart when the steering wheel is moved through excessive squeezing, twisting, and turning). I had to disassemble the ball joint after installation and grease it from the bottom with a special lubricator to make the part serviceable (a waste of precious time and effort). I have been satisfied with the quality of Federal Mogul products in the past. It is very frustrating to see them putting their good name on this inferior product. I will no longer be able to trust their brands in the future. (By the way, this product was made in Taiwan.)
