vertical axle play - Lateral-g Forums

How much up and down play should the axles have inside the housing? I can move mine up a little. Of course it slides in an out too since I still have the c-clips in.

I ask because I'm chasing a noise. It sounds like the rotor is scrapping as I go around a left hand turn. I don't have to be really loading the suspension either It's not a heavy scrape. More of a light weight one. It's definitely a rotational scrapping sound. I had the rear brake apart on that side and couldn't find anything. Happens whether I'm on the brakes or not. I'm fairly confident it's the rear driver's side anyway. Doesn't happen when going through a right hand turn.

It should have virtually no up and down play.

What rear brakes? Pull your pads and check your abutment to rotor clearance. You should have equal distance side to side.

Vertical play is worn bearings.

That's what I was expecting for an answer. Just thought I'd ask in case I was wrong. Oh well, I'm looking to get another rear end build for me anyway.

C5 rear brakes. I pulled the rear brakes apart yesterday and couldn't find anywhere that there was contact occurring. There was plenty of clearance between the rotor and abutment pad with the axle pushed in or pulled out. I have no interior in the car so I'm rather positive on the location of the noise. Guess I should look elsewhere too just in case.

Thanks

The outer edge of the rotor is tough to tell. Also on the inside of the hat where the parking brake sits.
You can spray a light coat of flat black primer on the suspect surfaces and go for a ride and try to duplicate the condition. It will make it easier to find.

True. I'll keep that trick in mind. I'm not sure what I'll do since I'm looking to replace this rearend. It leaks and has already had new ends welded on but the shop didn't do a good job etc. I'm ready for a new one that will hold up and is built right even if it does force me to change rear brake setup. It's only money, right?
