Im starting to get vibes over 50 and cant tell if its the axle u joints or the drivshaft joints checked all of them they all feel tight even checked my motor mounts and trans mount anyone got any other ideas? About ready to tear everything off and wanted some ideas to what you guys might think.

 

jsut because your u joints feel tight does not always mean that they are good. Too tight is just as bad as them being too loose. its hard to tell if they are too tight thought without taking out the drive shaft and checking it. usually the front axle joints will not give you vibration its usually one of the axle joints. Its possible the you may have a front hub bearing going out that is very common as well

 

Gonna pull my front shaft tonight hope thats it other wise hubs it is

 

I had the same problem with my 88 Wagoneer vibration over 50 it turned out to be the front shaft needing a overhaul 2 of the 3 the u joints and the centering ball yolk was shot I replaced them all not a hard fix at all no special tools needed here is a link that may help
