Review on ACDelco Professional 45D1103 Front Upper Suspension Control Arm and Ball Joint Assembly - Enhanced Performance in Sleek Black Design by Vince Preston

I've read some posts online about the difficulty of pressing out the top ball joints. I decided to pop out the bottom ones but replace the top arm to save myself the hassle. There are no complaints about this device as it works normally and is easy to maintain. After 160,000 miles on a Yukon XL Denali, this article is for you. One of the ball joints was cracked and would fail if I didn't keep lubricating it.
