  • Vibration under load? Help!!!

    I've had a vibration for some time, now it's getting worse. It started out under load and just in the clutch pedal. If I depress the clutch pedal ( not enough to dis engage it) 1/4 inch you can fell a vibration. It goes away once you take foot off the pedal.

    I've changed my tranny mounts, engine mounts, and now another Dvr side front axle. Still no fix. It's getting worse now, today on my way home I started feeling it my steering wheel and all over the car. I was getting really worried and it felt like something was coming apart.

    Swaped the Dvr side axle but still nothing, same vibration. I'm gonna do the pass side axle tomorrow night as I have one sitting around in the garage.

    I noticed there a tiny amount of in and out play in the axle flange on the tranny tonight. Is this normal? Looking for any idea to solve this. It's my DD and I need to to be solid. I have noticed the pass front axle clunk a bit when turning sharp out of the garage, no leaks in boots or any signs of defect. It's still the stock axle if that makes a difference.

    Any ideas guys?, has this happen to you? I've considered wheel balance but its not the same kind of vibration. I'm gonna switch to winters very soon as well.

    Thanks guys,

    Separating tire? Driveshaft?

    Best bet is to get it on a hoist and get a shakedown.

        Changed pass side axle, the boot was ripped. Test drive...no change. As for the above video, that is bad correct? Looking to have little to no play?

            Just a guess, but might this^^ point to a bad throwout bearing?

              I can feel it thru all pedals but I can feel it the most thru the clutch pedal, I have a apt booked at a local shop this Friday to have it looked at.

                x2 or your clutch throwout bearing or you have overheated your clutch. That will cause pulsing like a warped brake rotor

                  Shouldn't be a overheated clutch because when I overheated mine when I was first learning to drive it just slipped like crazy.

                    Not always if the clutch slips at higher rpm it can produce allot of heat warping the pressure plate, not saying this is the issue but something to look at if the problem can not be found.
