What causes cyclic vibration on a FWD drive?
On some FWD driveshafts, a “vibration damper” weight is used to control torsional vibrations. If the weight has been removed or lost, it may cause cyclic vibrations to occur at certain speeds. Worn U-joints on RWD driveshafts can cause vibrations at any speed as can an incorrectly installed U-joint.
Why do I feel vibration in the rear of my car?
Run your hand around the rear tires to feel for roughness. If the tread blocks are worn unevenly, you’ll probably feel ridges one way, but not the other. The fix here is to replace the worn tires and realign the rear wheels.
What is the difference between vibration and speed sensitive?
Engine speed sensitive — The vibration/noise is directly related to engine speed and nothing else (not vehicle speed or driving conditions). The symptom appears or changes in direct proportion to engine rpm. Vehicle speed sensitive — The vibration/noise only occurs at certain speeds or changes in direct proportion to vehicle speed.
Why does my driveline vibration increase with acceleration?
If the vibration steadily increases with driveshaft speed (either accelerating or decelerating) the symptom is primarily the result of a driveshaft imbalance or yoke run-out. Sometimes this yoke run-out problem can be improved by rotating the U-joint 180-degrees in the rear end differential yoke.
Why does my Dodge Ram have vibration at 60 mph?
Last fall I purchased a used 2016 Ram 1500 with 72K miles. The dealer had just replaced the tires. I noticed I had a slight vibration around 60 mph but thought the tires and new and had just been balanced when they were replaced. Anyway, I took it to a tire shop.
Why is my car vibrating at high speed?
Vibrations in a car going at a high speed can be caused by numerous issues. Most of these issues are found in the front end of the car. Vibrations in cars are usually experienced in old cars, but they can occur in any car, regardless of whether it is a sprightly new impulse buy or a battered family heirloom.
