Default Front hub bearing resistance.

Mods, please move if nessecary

In general, on a RWD car, how much resistance should there be in spinning the front hubs (with no brakes, discs, or wheels installed)? Should it free spin a bit or should it rotate easily but have minimal free spin?

Edit: hub installed and has abs and will easily free spin with brakes and wheels installed...

front, undriven wheel...yeah?

Once the initial mass is overcome it should spin with the force of one hand, easily.


if not, most likely the bearing preload is wrong or the wheel bearing is stuffed.

As a general rule in this scenario there would be very LITTLE resistance indeed.

The easiest way to get it right in general is to tighten the nut up firmish, while spinning the wheel, to seat the bearing. Then back the nut off, and do it up finger tight with no tools, put the split pin in and done.

What model car is it, someone here is likely to know what exact torque you need and then you KNOW it is right.

I back the nut off once the bearings have seated & use the weight of a 12" shifter falling to get the resistance just right.
Others may have differing opinions but that's what I was taught.
Failing all else, get a torque wrench and refer to manufacturers specifications.

It took me years to learn how to do this right...don't feel bad about being cautious about it seeing as how it's pretty important to get right...

The hub on my AU spins round and round more freely then a conventional set up on an older car with just plain bearings (pre AU), they dont really spin freely when torqued correctly.

The highlighted one. Will spin freely by hand but it wont keep going afterwards. Not enough mass there too. It will with the wheel on it.
