I'm doing a u-joint on a 2000 Chevy S10. Old one exploded due to whoever changed it neglected to grease it properly

Not only that, but ALL of the bolts that need to come off have completely rounded heads and overfuckingtorqued! who the FUCK thinks its a good idea to make the bolt heads round as shit to prevent future maintenance??? I'm all for doing vehicle repairs yourself, but when you have no clue how to do something, maybe it's time to have someone do it for you, or ASK someone. This should be simple job is turning into a nightmare, I'm telling you... Also this same person has been cruising around with no break fluid, and 3 of 5 studs snapped off the passenger rear wheel.
