[DeTomaso] NPT Which Front Wheel Bearing???

[Will Kooiman]

Front wheel bearings are easy.  Change 'em both.  They're cheap and easy to change.  Besides, if one side is going out, why wouldn't you also do the other side?

When my rear bearings went out, I rocked the car side to side with my hand on the rear rim.  The free play was pretty obvious.  I don't know if that's always the case.

When I mentioned this previously, someone said, "but if you do that, you'll dent the body".  You don't have to rock the car like a gorilla.  Just a little bit side-to-side, and if there's free play, it'll show.

       So when you turn left, you are weight loading the r front wheel and then that is the bad bearing. More load makes a bad wheel bearing talk out loud. 
    Rears are different as they are not subject to turning induced loads but lateral loadings. So for rears, you spin engine spin them up to 40+-mph and kill engine while holding down clutch. You will hear the noise/growl/rumble as they spin to stop with all other noises shut off. Only do this with wheels on as weight exaggerates the noise.
    Bad wheel bearings don’t always have freeplay.
