Excellent product. I've been on my third Ford Ranger since 1992 and all of the upper ball joints have worn out in 80,000 miles. A lousy Ford Motor Company design that was never repaired. For the first time in 25 years I have an oiler on the upper ball joints. I hope they last until the wheels fall off. Easy installation, perfect fit. I may not live long enough to reconsider 80,000 miles.
