    please confirm, I suspect I have a duff wheel bearing ....

    My 2000 1.7 diesel estate has a high pitch 'rubber on metal' kinda squeak coming from off-side front wheel bearing area. only noisey when turned slowly by hand. there is no play as far as I can tell in the bearing and it has only just started to do this in the last 20 miles. I have stripped the pads, calliper and disc off so it is none of them. I have cleaned away all the brake dust crud hping it was that but this has not helped.

    I'm thiking it's a seal binding somwhere but I read that they are sealed units .... was wondering if there is any way of sqirting some teflon / grease spray into the seals ???

    if it is the bearing what sort of life do you think it will have left ??? MOT in a couple of weeks!!

    Please confirm if it is the bearing or offer any other ideas guys???
    Cheers
    Ian

    A relatively easy way to check for a rough wheel bearing would be to jack the car up and spin the wheel while holding the suspension strut near the lower mounting bolts as the roughness from the worn bearing travels and you can feel it. A worn bearing is more of a dull rumble sound generally

    no roughness, it feels smooth and no 'singing' (yet) only this eeek eeek as you roll the wheel (or car) back and forth.
    I have put it all together again now (need it tomorrow) and looking closely noticed that there is ever so slightly more wear on the inner edge of the tyre, I dont know where this points (tyres have been on 2 years and I have had no issues with tracking / ballance ..... and I have hit no curbs!)

    I'm keen to know if it is the start of the end for the bearing, how long / mileage can I expect before it becomes un drivable/ un bearable, is it going to get noisier?
    cheers

    Astra wheel bearings often squeel when they are failing, they go dry in the nylon carrier unit and cause a squeel, you will not detect any wear just a dry unit. bearing will eventually seize up. i have changed a couple for this very problem

    Steve,
    So the bearing is going to check out soon, but how soon, any ideas ?
    Also ,would this be a MOT failure ?

    unless the tester can feel actual roughness and play in the bearing or squeeking when rotating the wheel by hand then it will not fail. mine squeeked for around two weeks before i got to changing it over, it is an easy job on the Astra

    cheers steve
    yours squeeked for 2 weeks ? can you remember about how many miles you did ?

    It's just a matter of me finding the time to do it or .... taking it somewhere.

    Can anyone else offer a 'remaining' mileage on one of these, I dont have the torque wrench for the hub nut so dont want to do this myself and the nearest garage I trust is 60 motorway miles away ..... will it get there or will it sieze ?

    it will get to the garage fine mate, there is no hard and fast rule of how long it will last, they go dry and squeel then without lubrication they will eventually rumble and then you will feel wear and play in the hub unit, they are well and truely shagged at that stage
