Drivetrain shake Can anyone tell me if you see anything wrong driveshaft wheels rear end, the car shakes vilonetly above 65
Took the wheels off and car shakes also. IT seems to be a little bit more violent when the wheels are on but the shaking is still really bad.
transmission mount is good so are motor mounts, also checked ujoints at both ends and as far as i can tell there is no play in them. putting it in first and revving up the engine does not cause the car to shake, its only in drive. any help would be appreciated.
video is about 4 minutes long and contains different angles of me putting it in drive and going up to 65-80

i pulled my driveshaft off today, and the ujoints were still good pulled off the cover to the rear end and all the gears looked good no chilpped teeth i guess it really only leaves the balance on the driveshaft

Is the vibration strictly speed dependent, or does it also vary with the amount of throttle? And even though the car still shook with the wheels off, I think you should check the balance weights on the wheels like LS6427 suggested. I read a similar thread like this a while ago and that turned out to be the cause of the vibrations.

what ive noticed is at a lower gear at higher rpms the shaking is worse, in top gear at about 60 it starts shaking and it get increasingly worse i dont feel it shake in the steering wheel just in the rear end
I wonder if it could be something in the transmission? If revving the engine in park doesn't replicate the shaking, I would think that'd rule out a pulley being bad. If it was the balance on the driveshaft the vibration would be strictly speed dependent.

check the universals yet? take the driveshaft out, and check to see if one or more of the cups is seizing. while it's out, grab the pinion yoke, and try to move it side to side, and up and down. it shouldn't move at all in any of those directions.
