Vibration between 55 and 65 mph

Transmission, drive train, and U joints have been replaced. Still getting serious vibration in the car between 55 and 65 mph. Stops when you reach 70. Any ideas?

    I just got the car back today and it has brand new drive shaft U-joints including a brand new drive train and transmission. The idler arm, upper ball joints, and brake master was replaced a short time ago and it has brand new brakes all the way around. New tune up and the alignment has been checked as well. Getting ready to have the tires rotated and balanced to see if this is an issue. Could it be the stabilizer bar?

I am a minor shade tree mechanic here so this is just a guess. It might be a front brake rotor, a break pad caliper that has a sticky hydraulic piston, front wheel bearing, or something else. Look at the pad and rotor wear for it possibly being a break system issue. Not sure, if you do not have a solid front axle look at the inner part of the wheel under the vehicle where the ball mates into the socket for any wet fluids or unusual gunk or build up around the axle and break calipers for a wheel bearing problem. Jack up the front end and make sure you chalk the rear tires, vehicle is in PARK and the steering wheel is unlocked as to where the steering wheel can be turned if needed. After vehicles front tires are off the ground try to pivot the front wheels to point in a different direction left turn or right turn. This can be tried by physically grabbing the tire trying to move the tire to point left or right. If the front tires are able to be pointed in a different direction without the aid of the steering wheel, then it could be a wheel bearing issue or a more serious issue. Hope you can make sense of these instructions, and hope this helps you find and fix any and all existing problems you are having with your vehicle.

SOURCE: Tire Vibration

I had the same problem. Vibrations start around 40mph, up through 60 . seems to be ok when I am off the accelerator. The problem was not dirty ETM rather a busted passenger side cv boot and axle. Fixed it and the problem is gone. The part from Volvo its expensive. Over $500. But OEM part can be had for less than $200. I have a 2003 s60 T5.

Lift the back of your car.With a stable rest and with the two hind wheels hanging, run your car up to the speed where you experienced vibration. have someone take care of the throttle and shifting while you observe the transmission shaft. You may have an imbalanced shaft.

If the tires are round once checked on a balance machine to be true. Next check the driveshaft is a weight missing, dings or bent, u-joints loose?

Then check the rear ring

Serious vibration when accelerating or holding speed; smooth when coasting


Hello,

If problem only occurs 'under power' sounds like a u-joint (driveline - rear wheel drive) or a cv-axle (front wheel drive). Check for excessive play, fluid, boot tear and breakage.

2002 Dodge Durango SXT 4.7L RWD shaking (serious vibration) badly between 70 to 80 mph


If it were me I would take out the drive shaft and check the play in the universal joints (I know you said they were replaced). Unlike ball joints they should exhibit good freedom of movement and flop from one position to the next as the shaft is rotated in the hand. Check that the bearing cup retaining clips are present on all sides. If there is any tightness in a bearing it is possible that either one of the cups has been pressed (hammered?) in too far or that a needle bearing was dropped from the outer race into the cup during assembly. Also check that the cup holders (arms) are not bent, sometimes if care is not taken to support the back of the 'arms' when installing the bearing cups the 'arms' will bend.

Vibration in the drive train at 40 mph in my 1993 Ford 150


I would check the driveshaft universal joints and the play in the yolk joints where the driveshaft exits the transmission and where it enters the differential.
It could be the preliminary vibration caused by the deterioration in a universal joint, forewarning you that it's on the way out. Good Luck Vern

Bad vibration in truck, not so much in the wheel but it's hard to tell. Starts around 30 to 40 mph and continues till 50 mph. A mechanic friend told me it may be the u-joints and/or (drive shaft) hanger...


that was good advice, it does sound like a u-joint, on these trucks the best way to check the joints is to remove the drive shaft, and flex each joint by hand to make sure each has free movement.
