Hello, I was wondering if any of you know about good greese for lubing ball joints, tire rod ends and all those little greese nipples under a truck. I saw that mobil 1 makes a greese for under a truck, is it any good or should I just use factory greese from the dealer. I have my own greese gun so I do it myself and would like o know what the best greese is for trucks to help the ball joints etc. last longer. Many thanks! P.S. The truck is a Chevy Silverado if that makes any difference.
