I have a 94' F150 xlt 2wd with the 302cuin, A/T. I had to cut my parking break cable because it froze up on me, I then had to replace the rear breakes, passenger front ball joints and spring hanger, and shocks. The next day, I started feeling a vibration (other then the suspected torque converter shudder that occurs between 3rd-4th and/or into overdrive)that seemed to travel from the seat to the steering wheel and eventually started to vibrate the entire truck. I checked the u-joints, they seemed tight with no sign of rust and the tail shaft seemed a bit sloppy to me. I havn't measured the backlash in the rear end or anything like that. The vibration gets worse every day and happens under load. If I "get on it" it smooths out a lot, if I shift into neutral it goes away. It is worst at normal cruising rpm's from 20mph - 55mph (i won't chance speeds any higher). Leaving work this morning it was really bad. I turned a corner and started accelerate when I heard a single knock/clank/bang, or something of the sort. I tried to think it through and all I could come up with was the spline on the tail shaft possibly skipping a tooth. The sound seemed right and the location of the sound, but I'm not sure if that is even possible. I don't know much about transmissions, in my mind I have narrowed it down to something between the fly wheel and the rear end. What do you think it could be? Something deffinately seems to be wearing out.
Any input is appericiated and I thank you in advance.
have the same problem?
