The main reason I used the lift was to see the vibration in the drive train . The vibration was more defined at 30 MPH and with the back tires off the ground and running it made it very easy to locate the problem . The dealer was trying to tell me it was not coming from the drive shaft and it was a tire problem . Around a farm you learn to put U-joints in at a young age , I remember putting them in my field car when I was only about 9 . Even at that age I did a lot better job then this dealer , were do they get these guys . I guess when all the K-marts closed Dodge was standing there with applications and a job offer .

 

This is the reason I don't want anybody to touch my truck but me. This reminds me of the loose drain plug thread.

 

When I ran my new joint in we just put it in drive with out the rear wheel on while on jackstands. 0-90 in 3 seconds. Not recomended
