My bushings are all in good shape.....I replaced all of the bushings a few years ago when I swapped in the 88 rear suspension/subframe. The wiggle is in the hub...I'm just surprised there is no sounds of any sort coming from the left rear- yet it wiggles quite a bit....

Because of my heavily modded suspension I check things over a lot. I noticed some play in the rear passeger wheel, not making any noises so I checked the torque on the axle nut and it was around 20lbs light. I dont know if I forgot to torque it all the way or it just loosened off. I retorqued it and gave the locknut a good pinch in and I have put about 500 miles on it since and it seems fine. This is a replacement hub, the other side is still original. ------------------

I was just checking my old bearing- clamped in a vice- checking the wiggle- and it just came apart.....Isn't there a retaining clip or such in there? It shouldn't just come apart, right? (Thank gosh the axle nut was holding it or the wheel could have rolled off)

These old style bearings can fall apart if the axle is not bolted in. People have found that out the hard way pushing a car around a lot or worse towing it with an axle removed. ------------------

So here is my rear hub/bearing that fell apart.........You can see the piece that is supposed to hold the hub on the bearing carrier...I suspect that on later versions (Like my 1988 Fiero hubs) that part is swegged on so that it won't come off....This one was not in any way even close to being swegged. It slid right off on the work bench and was smooth.....

The "end piece" is the inner race for the inner row of balls. Since the basic arrangement is a dual row angular contact ball bearing, the inner races see significant axial loading, which pushes them apart if they are not adequately retained. The inner race on the "spindle" was a light press fit when the hub was originally assembled, but that fit was damaged by running it without an axle.

If the inner race I mentioned above has worked loose, then the bearing can acquire play without the spalling on the race or balls that causes wheel bearing growl.

This is my original 1985 Bearing that came with the car originally....Never been run without an axle.....I can see no suggestion of swegging- and it is a easy slip fit- no tightness at all.

The rear hubs will come apart without the axle nut on all years.
The torque setting on the axle nut sets the bearing preload.
You can not get an idea of a rear hubs condition unless it is torqued to spec.
