[DeTomaso] NPT Which Front Wheel Bearing???

[Asa Jay Laughton]

Could be front, could be rear.  Nowdays these kinds of things can 
transmit far from where they are, but not always.

I recently had what I thought was a front wheel bearing going bad but 
had a terrible time finding it until a friend recommended I do the 
following.  For the front wheels, he said jack it up so each front wheel 
is free and hanging from the suspension.  Grab the coil spring and spin 
the wheel.  Whichever spring feels like it's vibrating, that's the 
bearing to change.

And I'll be darned, it worked.  I could not feel any roughness when 
turning the wheel or carefully feeling the hub, but by lightly holding 
the coil spring, BINGO!  I changed that bearing and all was good, no 
more vibration or weird hum.s  This was on a front wheel drive car too, 
so it could have been the CVs, but they were pretty new and the problem 
did not change much in corners.

Your mileage may vary.
