Wheel bearing has pitting on races

[Jetronic]

I wouldnt have wanted to put in chinese bearings if they were going to fail sooner than japanese bearings.the mechanic says he didnt torque the wheel axle nut to 137 ft lbs(factory spec) because his torque wrench only goes to 120 lb ft, so he torqued it by feeling with a ratchet wrench.

So i dont want the bearings to be tight( lower fuel economy, shorter bearing life) or too loose ( shorter bearing life) so he told me that he would torque to 137 ft lb if i got a torque wrench for him to use., so i will see if if i can borrow a torque wrench or worst case scenario buy one to get the axle torqued to spec.

I wouldnt want to drive it without the axle nut torqued to spec to get a mechanic with a torque wrench to torque it as on the way the incoorectly torqued axle could shorten the bearing life substantially.

As said in the previous post, this type of bearing is not as dependant on tightening toque, if the play is removed it's all good. The nut won't come off when torques to 120 ft lbs and then some. Might even be better than using a random torque wrench that's never been checked or calibrated.

What play has to be removed?

I bought the car about 15k km ago - around 10 k miles ago. Before that it had supposedly 170k km supposedly - 100,000 miles. So maybe the bearings are at least 100,000 miles of use.

The play you have when the axle nut is not tight. You don't have that.

The damage on the old bearings looked like ity had been done putting the bearings in, Maybe from the factory but doubtfull.

It's 30 years old. Over that time the grease could have dried out, water incursion, etc.
