Does anyone know of a particular brand or type of grease that won't drip oil out of ball-joints, u-joints, tie-rod ends, grease fittings, etc? I've noticed that my grease gun that hangs on the shop walll when not in use drips oil from the nozzle tip and pump plunger. It appears that the base oil is separating from the thickener and running out, whether it's still in the tube or has been applied. I asked the guy at the parts store if I could get a thicker grease, but left him scratching his ass. I'm presently using Valvoline multi-purpose grease (Chrysler, Ford, GM and Japanese). I've heard of using marine grease but want to double-check with the HAMB before doing anything. Thanks guys.
