under a heavy load (up a trailer, water wheelie) something pops, feels, sounds like its in the trans. This seems to happen in 1st gear, although I havent tried to do anything tough in any other gear. IM thinking it could be the u joint maybe?? Only seems to happen when the wheeler is going "up".
I jus gave it a good bath, and I plan to inspect the U Joint, if this is indeed the bad apple, what should I be looking for?
