Default Can a rear wheel bearing be changed by an intermediate mechanic with basic tools?

1996 legacy outback AWD, right rear wheel makes noise when i turn left, quiet when turning right, im guessing its the bearing, after looking at some threads here it seems like quite a difficult job and id need some special tools? local shop wants about $400 to do it,

disk rear brakes not drums

should i try?

anyone near 95066 want to come and do it (for $399?)

is noise from the rear alway a bearing? anything else i might check?

incredibly it was the hub bolt (32mm) it was LOOSE !! i could move the wheel back and fourth vertically 2 inches, loosest wheel ive ever seen on a vehicle in 30 years.

3/4 turn and a torque wrench, and a good smack with a hammer and chisel to keep the bolt fixed in place all is well again.

scary,

weird design if you ask me, the whole wheel (hub) is held on by (1) 32mm bolt???

I think it's very common on a driven wheel. The other option would be to hold it in place by press fit only.

Also, that nut puts preload on the bearings so it needs to be tightened with a torque wrench. Something like 150lb-ft off the top of my head. Since yours was so lose I wouldn't expect them to last much longer.

we usually just end up swapping out the hub for one with a good bearing, we also have a slew of parts laying around, and good idea on the torque jamal, ill have to look into it, maybe the same thing is going on with my car, just needs axel nuts torqued again, wouldnt surprise me as everything else has rattled its way loose...... really fun when its your intake manifold.

my axle nut loosened...and tightened and then had to replace the bearing. Floppy wheel can damage the bearing.

If your wheel was THAT loose, the bearing is in your future...

I pull the knuckles and take them to a local shop and they press the bearings for 35$... easy peasy

100$ total, no press BS for me... I've had reports of nearly MAXING a 60 TON press at one shop.. Had to take it to a 2nd shop because the 10ton press at the first wouldn't budge it..

I thought axle nuts were one time use, due to thread stretch. Has that axle nut been removed before?

im no engineer, but id have thought some kind of cotter pin through the 'axel nut' would stop it from loosening itself, or 2 nuts that tighten/lock against each other. it seems like a well designed and built car but the wheels not coming off accidentally is important, 3 minutes thought at the design of the hub / wheel assembly process could have prevented all these reports of loose wheels and damaged bearings.

the axle nuts are staked and shouldnt turn on their own...but the world works in the ways it does and that means they DO loosen over time

and if the fix was that simple.....then it would have been done long ago

if this scares you....you need a bus pass not a car to drive

If the axle nut is new and properly torqued and staked, and the hub/bearing/upright are good, it won't come loose. And I've seen a couple of bearings that were so far gone the parking brake and tone ring got destroyed, but haven't heard of a hub coming completely out of a bearing and a wheel falling off (plus the brake caliper/bracket should keep that from happening).

Subaru......[mirror]......urabuS!!!!


I agree that the nut loosening would be really bad for bearing longevity. OP may get away with it for awhile, but it's destined to be the next bearing to go bad.
