My '98 'burb - 150k+, never had a wheel bearing replaced - has started making a rotational-related noise.
Gonna take it to the shop tomorrow, but my money is on their telling me that they can't hear anything.
If that's the case, it seems like I've got two choices:
-------------------------------------------------------
1) Wait and see2) Just replace both front wheel bearings preemptively
-------------------------------------------------------
So... what's the failure mode of a front wheel bearing?
Gradually noisier and noisier until just about anybody can hear it and then failure at some later time?
Or can there be a catastrophic failure even when it's not making any noise?
Seems like one thing in favor of Plan B is the number of miles on the vehicle. Those things can't last forever.... and maybe it's about that time anyhow...
