Around 30mph a vibration comes from the right rear of the car. whats the likelyness that its a wheel bearing?

I would have the front wheel bearing adjustment checked first as if they are loose the rotor will be rubbing on the pads and the vibration will be wheel wobbling on the loose bearings Unless you replaced the bearings with new ones then they will fail especially if the adjustment was too tight and too much grease was used.

first swap to a front tyre to eliminate that issue


new bearing shouldn't be rumbling
to get the bearing square on and home
did you use a press to fit the bearing to the rear axle
or tube method ?

and did the seal kit have this nifty plastic seal fitter so axle didn;t rip the seal surface

sounds like a wheel bearing.

Have the CV joints checked for to much play...worn out...like a warped drive-shaft on older rear wheel drive cars. Hope this helps.

Have you checked the wheel balance on the front wheels?

Hello. It could be the beaing or it could be the tire itself. Get it up in a rack to push and pull on the tire to check the bearings. IF it doesn't move around, it could be the tire. Rotate that tire to the spare or to the rear and check that out. J.

This certainly has the sound of a bad wheel bearing. Be sure that both front wheel bearings are good, as I have many times seen professionals pick the wrong bearing. Another possibility however is that the cv shaft or drive axle is making the noise. A bad axle will react very similarily to a bad bearing. Try moving the axle in and outward towards the transmission if there is play there it could vey possibly be your answer

Unbalanced tires wont give a vibration all the time at low speeds.Have them balanced and check wheel bearings and ball joints.If it still persists then have the prop shaft balanced

Check your u-joints in the rear driveshaft.

if it is sure break fluid. then you have to change break master cylinder, if your car rear wheel drive that might be shaft oil and vibration come from a worn rear wheel bearing.
