Are you sure that the joints are seated into the coresponding sockets? I find that the vehicles that I work on frequently have the bolts tight but the parts aren't seated properly.If uncorrected they end up loosening the bolts and breaking and throwing the drive line.Either end ,boy does that make a mess.I can't emagine driving when that happens.I'm talking about Millitary M113 personel vehicle. Mostly the vehicles were just thrown together and the failure happenes while being towed.It ponds and caves the 3/8" alluminum wall between the drivers feet and the driveline to death. Welders spend a lot of time patching after I've removed everything in that area.
