Axle nut loosens by itself. Help?

Ah, okay! Glad you got that all sorted out!

And good to know those teeth are removable! :)

you were right from the begging haha

[Batz]

Nice!

So what do you mean by the "hub"? I always consider the rear "hubs" to be integrated with the trailing arm. I guess the "hub" might also mean the flange that you press into the bearing? If that was the problem, I'm curious how.

Thanks!

Som

Wait sorry, idk why I said the hub. I meant the axles. Part of it I guess I can blame on myself but catuned is also to blame for such "great"instructions (none) the "teeth" for abs cars are apparently removable, and I didn't figure it out at first so the axles were never in all the way and couldnt move because they were pressed against the trailing arm.

The hub was fine haha.

alright found the issue, it was the hub, thanks a lot for the input guys. Car is driving nicely now.

[Batz]

That's the thing... I have locks.. the nut doesn't move... At all.. it seems like the hub just goes farther into the bearing...

The axles can't move out from the diff because the trailing arm is in the way correct? so the only thing I can think of that can move is the hub?

It's just thoughts, I might be wrong.. first time rebuilding the suspension..

[nando]

why don't you use the lock rings? I don't normally use them, but it would definitely prevent it from backing off.

[Batz]

If nothing helps and I won't figure out why, friend has spare axles, I'll borrow his and check.

[FredK]

Yeah, pull the axle and check for rub marks in the trailing arms. Sounds like Som nailed it, and really went above and beyond researching the issue.

[Batz]

Thats what i have been thinking as well. It logically makes sense, right?

But catuned states on their site that they work for both, abs and none abs cars. I also know people who used their axles with none abs cars and they worked fine, for exaple JGood. I am really hoping that the problem is not in the axles because catuned costumer support service sucks and i doubt i would even be able to return them, in which case i waisted $500.

Thanks for the input tho,

I didnt have time today to try anything, will try to do something to the car over weekends and maybe will find the problem. (Fingers crossed)

Wonder if this has to do with the axle type. Apparently there are different axles for ABS vs. non-ABS cars.

Searching your other posts, it looks like you have an '84. I'm going to guess you don't have ABS, and I'm going to also guess CAtuned doesn't sell a non-ABS half-shaft. The second page of this thread touches on the subject (http://spece30.com/forum/48-drivetra...factured-axles), but there may be better threads about it. One post in there even mentions that trying to use the ABS half-shafts in a non-ABS car won't allow the wheel to turn.

In particular -- djjerme's post near the bottom of that page states:

This is a very common miss. And most "experts" state the same. There are early NON-ABS hubs that the later ABS axles WILL NOT FIT IN. Even with the ABS reluctor ring removed, THEY WILL NOT FIT.

Feel like I should state it again, because people will still refute it..

THEY WILL NOT FIT!

After spending three days earlier this year when I had a joint fail, we tried multiple used and reman axle shafts. My chassis is a very early-85, non-ABS car, and the none of the late model shafts would work. The spline count was the same, but once you tried getting them seated, they hit the housing and would never fully engage (let alone allow the axle to turn.)

It was only when we found a reman that had the earlier, smaller shouldered CV that it went together smoothly and rotated freely. And yes, this was a medium case car originally.

I'm guessing the added material for the ABS notches interfere with the back of trailing arm hub area. So when you tighten the nut on the half-shaft, your pressing the ABS notches against the trailing arm hub -- preventing it from rotating.

These are all guesses -- so worth investigating further.

Good luck!

Another thing i noticed, i put a mark on the axle nut and the axle itself. Then i drove the car for a bit. Wheels started to shake, but the axle nut is on its mark, so it didnt loosen itself..... How the hell is that possible?

[reelizmpro]

Something is wrong...go have a look. Might have to pull the axles.

[Batz]

The bearing was also replaced by a friend of mine who is a mechanic and has a shop.. so i think the bearing should be fine.

[ButtJuice]

Could it maybe be a problem with the bearings?
