I drive a 1992 Camaro RS. I recently replaced my wheel bearings and races because they had become too worn out to properly adjust. All was well and fine for about 3 days. Since then the nut responsible for securing the rotor to the axle keeps loosing itself until my wheel developed a dangerous 1'' play. I have re-tightened the nut several times and have the castle nut and cotter pin properly seated. When i re-tighten the nut the wheel wobble is eliminated.

What is causing this nut to loosen up after only a few hundred miles? What can I do to correct the situation?

Thanks!

 

How did you set the bearing preload?

 

I did as the manual suggested. Spinning the rotor and turning the nut until snug. Then back it of a bit

 

A castle nut with a cotter pin through it can't loosen without the pin shearing. You've done something wrong in installation.

 

Take a picture of how you have everything installed. Particularly the castle nut and cotter pin.

 

Did you seat the races? Sounds like they are pushing in.

 

yea, like some of the others, I'm kind of curious what you're doing... with the cotter pin installed (nut properly installed...) it can't come loose, I don't think you could shear the pin trying to remove it with an impact gun, much less just driving it.

 

it would seem that the races were not properly seated and were indeed pushing in as i drove. That is what caused the space and the wobble. A bit of adjustment fixed her right up! Thanks guys
