  • BAD Vibration

    So when I went to the track last at speeds of say 80-90 i had a bad vibration going, and only at those speeds. Well now the whole front end/ whole cab fis shaking violently and vibrating from speeds of 25 and up. It clears up at 60 and 70 cruising speeds but its not really drivable. Any ideas...
    I'm going to check under there ASAP.
    Please stay tuned because I always got questions lol.

        alignment doesn't cause a vibration.
        tire balance, driveshaft balance

                    I had a BAD Vibration at 60mph and up.
                    It was the stock yolk that went into the trany.

                    If it's like min it should have a rubber damper with a steel ring on the out side of it.
                    I blew mine racing and I didn't find it for 2.5 yrs. because I didn't know about the damper.
                    I switched to a solid yolk and that fixed my isue.

                    If you have a respectiable drive line shop I would take teh shaft to them and have it checked.

                    It is posible that you blew a belt in you new tires also.

                      Is it a shimmy, or a vibration? Do you feel it in the wheel, or in the seat of your pants? Check the Driveshaft for sure. If you need one I have a good stock shaft I can let go really cheap. Also check for a loose wheel, or bad front wheel bearings. It could also be a really bad ball Joint. Good luck

                          okay there is some small fluid puddles under the car near the rear end. also i swiped a fresh drop of pink tranny fluid off of the exhaust. the puddles arent pink but they dont have that nasty rear end smell to them. i am very confused. the puddles arent oil and are not trans fluid, so it looks like rear end blood.
                          im so confused and T'd off.

                            i revoke that last statement.
                            it appears as tho that link/bar the the drive-shaft runs parallel too and the rear end sits on, is where the tranny fluid is dripping down to the ground from.
                            hmm..
