So yeh, always get good tips around here. Got a new issue. When I drive my truck, it has begun to violently jump and shake. I can not go past about 20 MPh. If the clutch is pushed in or in neutral, engine sounds completly normal. I don't believe it to be in the transmission. It feels like it's in the front wheels. This was a sudden thing that happened randomly the other night. I then had the joy of a 15-20mph drive home...about 30 miles...that sucked pretty bad haha. Anyway, tomorrow I should be able to jack it up and start tinkering. And suggestions on the possible problem, or an order in which I should check things?

 

Has it been converted to front disc brakes. If they freeze up, they will do something similar.

 

No, pretty much all original. Had a buddy come over to get an opinion, he is saying he thinks it to be clutch related.

 

Hooray!!! Ujoints. Quick and cheap fix.
