rear wheel bearing W211 2004 220 cde

[pomm001]

I turned the radio off this morning on my way to work, and when coasting at about 30 mph on a less than perfect road i heard a rotational 'wur'wur noise like a wheel bearing in its first stages of giving up the ghost, i havent looked yet to see if its anything else, but guess it the start of the bearing. i have 75 K miles on a 2004 e class:
My question today is
what sort of a job is it to replace, either at home, or any idea what the cost would be at the dealer or indie

many thanks

Unless you have a comprehensive tool box and a hydraulic press then I would trust this to a garage of sorts. Cost? Bearing about £60, time about 2 1/2 hours.

many thanks

At 75k your bearings shouldn't have gone yet surely. There are plenty of cars with well over double that mileage no no sign of any bearing trouble.
Far more likely it's a brake or other catching issue.

Wheel bearings are a rare occurrence these days, but a pot hole could damage one, Like anything just the odd one can come through

Hello Pomm.
Your Bus does not seem to have covered enough miles to be suffering from a failed wheel bearing unless you have hit something hard with that wheel recently.

You sound like you have some decent tools and some mechanical skills.
My first suggestion is to take this vehicle for a run of about five miles or nine kilometres and check to see how hot the centre of the wheel is. Compare this to the non complaining wheel.

If you detect the noisy one is hotter than the other one then this may suggest a problem with the bearing in that wheel. I would suggest the noise you have described (for want of a better description ) is not a usual wheel bearing failure noise.

I would suggest that you raise the part of the car (rear or front) from the suspect wheel perspective. Ensure to apply handbrake and chock all wheels not to be raised. Insert car jacks under the raised portion of car and adjust to height of car "chasis". Rotate the suspect wheel. Do you hear a rumble type noise? Check the other non suspecting wheel by also rotating. Does this wheel make the same noise or is it different? Is there any end play in the suspect wheel?

If you discover that there is a distinct rumble emanating from the suspect wheel then this will require immediate repair action.

Warning
Do not under any circumstance continue to drive the car without repairing the bearing. The bearing will eventually seize, destroy the stub axle and the wheel may detach and is likely to do so at speed,under load, without any notice or warning.

Let me add this is for a rear wheel bearing, sorry about the confusion.

Thanks for all your replies
Drove the car home from work and listened again, definatley the rear but only audiable around 25 mph, above that other road noise drowns it out .
Tried coasting very slowly with engine off in neutral, yes i know dangerous, no brake pump etc but could hear better, still there.
Had to leave it until the nest day to check in the light.
Well its not the start of a wheel bearing, its a small coach bolt and washer on the edge of the tyre, it stood proud about 10mm from the tyre ,hence the dramatic noise, normally a stone in the tread is more a 'click click'
So a new tyre has fixed the problem,together with a large slice of humble pie for jumping to conclussions before having a good look,
