Default Lateral Play in Axles

This is something that I've lived for as long as I can remember with the TA. This is my 4th f-body, although 3 have been 2nd gens. I've never experienced this before. I don't think that I'm alone with this. So I'm driving down the highway and the TA is going in a straight line and it just starts to veer one way or another, but I resist the temptation to correct the steering .... and it catches and corrects itself. That is happening in the rear (rear steering) where I would guess there is 1/4" axle end play on each side. I've read where an external snap ring could be installed at the end of the axle to eliminate that play. It just feels sloppy as hell. All parts are good too. Is this something in the aftermarket axles? I have Mosers in there. It's on it's 3rd set of axles and Ive always replaced them with Mosers.

What can be done to tighten up the axles on the 10 bolt? With a total of probably 1/2" of lateral movement in the rear, it feels like the rear is sliding around back there.

You have to measure the axle end play with a dial indicator, max should be around .125 thous or 1/8th inch per axle which feels like ALOT that why you have to measure it. I seriously doubt that is you handling problem. These cars have wide tires and are kinda hard to get them to handle neutral. Setting the camber 0 to slightly negative with 0 to slightly negative Toe helps a lot. Also caster needs to be set properly before any of this. Another BIG issue is the trust angle on the rear end. Good Luck finding someone who truly understands all this because it truly is a fine science. I do my own IN THE DRIVEWAY and my car doesn't wear tires and handles fantastic. You wouldn't believe how little it takes to make these cars handle like sheeeet.

The alignment is -.3 camber, 4.8 caster and 1/16" of toe in. I also believe you about the handling .. these cars are finicky.

all that holds the axle in is the C clip on each, and that is what wears thinner in addition to maybe the paddle block or carrier which they ride against, when a push or pull force is placed on the axle.

you'd want to measure thickness of a brand new c-clip and compare it against the thickness of a used one. if i rebuild my 10-bolt that is one of the things on my list to figure out. I don't know/remember if they sell new c-clips that you can choose the thickness of.

i'd have to look at it again but impression i had was it's not a good design for road racing where there's a lot of in/out force on the axle, it would wear down and create that excessive axle movement... which simply happens after ~100k miles.
