Hello everyone I have a 85 gs and when I went to install new shocks I realize that I needed new ball joints, tie rods and the list goes on. While it was apart I went ahead and got new brake pads, rotors/hub, and wheel bearings. After I finally get to installing it all back together and put it on the car I notice that there is some play in the rotor itself. I tightened down the nut inside of the rotor fairly tight but I was warned to not over torque it. With the brake caliper in place it holds it mostly in place but there is still just a little play right now. Is this normal or did I screw something up? I have a feeling I screwed something up since this is also the hub assembly so if the rotor is wabbling around, while driving my tire would be doing the same?

 

There are specs in the FSM about how to set the bearing preload.

It is bad to overtighten it (excess bearing wear, or in extreme cases spindle failure), but it has to be a lot tighter than most people expect. Should not be any noticeable axial or radial play.

Final result is some number of pounds of force applied to the rotor at the lug diameter required to make the hub turn. You can use a spring scale to measure this, or you can hang a measured weight from a lug installed at the 3 o'clock or 9 o'clock position; I used to use my dive weights before I bought a spring scale.

 

I think that I may be missing something internally in the rotor for the wheel bearing. The inner and outer bearing are both loose fitted inside the rotor. Is there something I should of transfered from the old rotor to the new one that maybe I didn't recognize? All I got are the bearings that I packed in with grease, and the outer seal on the inner bearing and the outer bearing I got the bearing I packed and then the washer and nut and cotter pin.

 

Come to find out I forgot to install the races.... All fixed now though! Got no play at all in the tire

 

That will make a difference, yes.
