Shoutout to the guy who showed me the grease gun trick on a stuck U-joint

Honestly, last Wednesday was shaping up to be a nightmare. I was underneath a 2015 Freightliner Cascadia trying to get a seized U-joint off the driveshaft, and nothing was budging. I'd been at it for over an hour, heat, breaker bar, the whole deal, and my arms were shot. This older mechanic from the bay next door walks over and goes 'try pumping grease into the zerk fitting till it pops the cap.' I laughed at first, but Ngl, after I hooked up the grease gun and pumped about four good shots, that cap popped right off with a little tap. I spent the next 20 minutes just shaking my head thinking about all the time I wasted on these things before. Has anyone else found a weird trick like that that just saves your whole day?

Man that grease gun trick saved me on a 2014 International ProStar last fall. I was ready to torch the whole thing off after two hours with a pickle fork and a sledgehammer. A buddy of mine who used to work on heavy equipment told me to try it. Popped the cap clean off in about three pumps. Still can't believe how simple it is.

Honestly @miaprice I feel your pain too, sometimes a torch just feels like the only way out of that mess.

@thomasb41 I still think a torch is faster most days though, right?
