Bought this stuff to lube the slip joint on my truck. Everything else I tried eventually scraped out of the slip joint and I was pretty much steel on steel. I used this on the old driveshaft on my truck and was more than impressed. Replaced the driveshaft eventually, and I will never use anything else for grease for the slip joint or double cardan joint. This stuff just stays in place. Worth every penny. Sure beats the Mo****1 to no end.
