Rear Wheel Bearing or Normal - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Was doing alignment and spinning rear left wheel and felt resistance. Right rear wheel was ok. Obviously parking brake was off is this normal resistance from diff?

Can someone check theirs?

normally there will be some kind of resistance on the drive wheels so i would say this is normal.

Just checked mine both in gear and in neutral. Felt identical left to right.

Parking brake drag? Caliper drag? I would exercise the P brake; remove the caliper; remove the rotor. Stop each time to see if it makes a difference.

BTW, thanks for your significant contribution to the community.

Thanks appreciate it, will double check that when doing brakes this week again.

If it is a wheel bearing you'd hear it growning with a low wa-wa-wa-wa type noise (it's almost impossible to describe a noise through typed words) that would change frequency with speed.

More than likely you were feeling brake drag. Separate the brake pads from the rotor (a screw driver works fine) and give it another spin.

Seriously, spent almost 24 hours in 2 days in a 100 degree shop, losing mind.

Thanks will check all that. Tires are so loud hard to tell if noise is bearing or not. Will check brakes.

When wheel bearings go bad, they tend to have a low frequency grinding noise that gets worse if you put more load on that wheel (i.e. turn the car to put load on the wheel).

You won't be able to tell a bad bearing by simply spinning the wheel by hand, you'll usually first hear it while driving.
