Why is my rear wheel drive vibration so bad?
Otherwise, as with FWD vibration problems, it’s really a process of elimination. Start with the cheapest, and work your way to the more expensive. Inspect the U joints first. Look for loose ones or orange dust around the bearing cups. This indicates a lack of lubrication, and likely means the U joint is on its way out.
Why does my differential feel like it’s vibrating?
Differential vibrations are almost always caused by a lack of lubrication. Sometimes water gets into the differential. If that’s the case, make sure your breather is intact and not in a place where water can get in. If your differential is low on oil or has water in it, get the water out, top off the fluid and recheck.
What causes a vibration in the center of the axle?
The center bearing might be part of a complete axle assembly, so you might want to check the center bearing first if you suspect a problem, as the new axle should come with new U joints. Differential vibrations are almost always caused by a lack of lubrication.
When do rear wheel drive differentials need to be replaced?
If your differential is low on oil or has water in it, get the water out, top off the fluid and recheck. Don’t have a lot of hope here. If you have a vibration and one of these conditions, it likely means that your differential bearings are bad and need to be replaced. Differentials are normally either good or bad.
Why does my car vibrate when accelerating and decelerating?
When accelerating and decelerating, however, there’s enough load on the driveshaft and joints to cause vibrations that will increase and decrease with vehicle speed. It will be most pronounced when first stepping on the throttle hard and when the brakes are firmly applied.
Are there any vibrations in rear wheel drive?
Rear end vibrations are even more difficult to track down than FWD vibrations. It’s very difficult to find the source of a driveline vibration in a rear wheel drive vehicle. As with FWD vehicles, make sure your tires and tire balance are good before you look to the driveline.
Differential vibrations are almost always caused by a lack of lubrication. Sometimes water gets into the differential. If that’s the case, make sure your breather is intact and not in a place where water can get in.

When do I decelerate do I feel the vibration?
It generally occurs at decelaration from about 60-65mph or when I’m going down a hill, when I habitually feather the accelerator to regulate my speed regardless of the slope, and rattles the whole truck to the extent I can feel it through the back of the driver’s seat.
