Thread: Wheel bearing?

  1. #21
    The shop suspected it was the left rear wheel bearing, but wasn't overly confident. I agree that the noise is coming from further back in the car, and from the left side so I'm thinking it isn't driveshaft-related. How bad is the rear wheel bearing DIY assuming I get the right bearing puller tool(s)?

    I only did the front wheel bearings. Rear ones don't usually fail.

    Gotcha. Do you think it’s the same procedure to do the rears?

    Update: I've had 2 shops look at it. Both seemed a bit less than 50% confident that it was a left rear wheel bearing. I don't think it's a wheel bearing b/c 1) the noise isn't a "drone", 2) it isn't impacted by lateral load, and 3) it is sometimes not audible for a few seconds but then it will come back - if it was a wheel bearing I would think the noise would be pretty constant at a given speed.

    The rear wheel bearing replacement is a bit more complicated than the front as you have to deal with the drive shafts - seems to be quoted at ~3 hours/side.

    Ugh.

    Update? I got the wah wah wah noise. Replaced one front wheel hub - I think it is less now. The other front wheel bearing?

    My noise was a rear wheel bearing. I wasn't very confident in the diagnosis (neither was the shop) but it turned out to be right. Slight lateral load didn't impact the noise, however higher, sustained load (i.e. smooth on-ramp) did impact the noise. I only tested it under milder load so I had convinced myself it probably wasn't a wheel bearing.

    Try putting the rear seats down to see if the noise gets louder. If not, at least you know your remaining noise issue is at the front end.
