Rear wheel bearing?

[werD]

How common are wheel bearing fails on the 4th gen T4R?

Wife's T4R went over to our local NTB for new rear tires last year after she grabbed a chunk o' metal in one that mandated a replacement vs. patching.

Since then she's had a funky noise coming from the rear (a subtle whup whup whup at freeway speeds). NTB said it is the bearing, not a tire when we took the truck in for new tires on the front this past weekend.

Before the tire replacement the truck was smooth as glass and exceptionally quiet. The truck has ~108K on it so it is very likely the bearing is tired, but I think it odd that the noise appeared instantly with the change in tires (same make & model of tire - Yokohama Geolander HT/S, it serves her well).

And thus, my curiosity in asking...

pretty common if your diff breather is plugged and all the pressure pushing the diff oil in to the bearing grease

D'Oh! Didn't even think of that... Must. Check. Breather.

not very common at all

Imagine that, a dealer putting the blame on something else and trying to make money on the repair.

Tired at 108K ? not likely, possibly 208K, maybe 308K.

I drive a MINI... So anything beyond 40K miles of use is subject to suspicion of fail.

NTB didn't offer to fix, that was just their "evaluation". I'd never do mechanicals at NTB - that would be a high risk adventure I fear. I wouldn't do tires there normally except they are the only place on my side of town that stock Yokohama tires (and the other shops are equally adept at being a$$hats - so not worth the drive). A shame since way back when as NTW, they were really typically a decent tire shop.

Anyway, not being there to witness the work, I suspect they didn't even pull the wheels off and look. I'll have to take a look at it myself and see what is really going on.

Overall, just trying to get a better feel for the ordinary/strange of maintenance with the T4R as we want it to roll another 100K without major pain. Fortunately this site is proving a great resource, and affirming my notion that the T4R is pretty bullet proof.

Without some other problem contributing to their failure, the rear bearings should last 300K easy.

Good deal - thanks.
