Not a Chevelle, but there is a lot of experience here so...

Helped a buddy replace the front hubs/bearings on his ford exploder very recently. The hub and bearing is a complete assembly.

While we had it apart, we swapped the rotors and pads.

Now he has a tire-speed dependant squeek/scratch.

I checked the lateral runout on the rotor, .005"
The hub flange has .002" runout, it's radius from the axle centerline is just under 1/2 that of the rotor.

I am pretty darned sure the new hub/bearing assy is the problem.
I was going to swap hubs from left to right to show him the problem would follow, but we ran out of daylight and his wife started nagging him.

We put a different rotor on there and got the same runout results, .005"

I want to replace the hub bearing, he's a cheap ass that wants to be sure before dropping the dime on a new one.

any opinions everybody?

I'd have them mounted on a rotor lathe and have them trued up with a minimum cut.

Truing the hub???

No, I'd true up the combination. That's the way they will be on the vehicle. I used to turn a lot of rotors when I worked in an auto parts store. When you turn a rotor attached with a greasy bearing, I would wrap the bearing in a plastic bag with a rubber band holding the bag to keep the shavings out. It works quite well. I would sometimes use a cone on the bearing side and a drum fixture on the rotor side to keep the bearing from spinning. Every set-up is different. You just have to be willing to experiment to get the right combination.

If I could verify that the "new" hub was out-of-true, I'd return the hub for warranty replacement before I'd cut a perfectly good rotor to offset-match the bad hub.

Yeah, I agree.

Too bad he bought the hubs over a year ago and just now got around to putting them on.

The way he goes through brakes, cutting rotors to make up for the offset isn't worth it.
