What's wrong???, rotational thumping sound Options

[Rymaster]

Okay, so after replacing my clutch, Which can be seen here

I've having yet ANOTHER transmission issue i believe.
Everything worked great after doing the clutch, until about a little over 1,000 miles after the install.

When moving, I'm hearing this rotational thumping sound from the axles is sounds like.
Over the course of 3-4 days it got so bad i took the car off the road and jacked it up. The sound comes directly from where the axles connect into the transmission. Its directly related to speed too....the faster the car goes, the faster the thumping. So it doesn't matter if I'm in gear or not, it's all about the present of speed and how fast they are rotating.

My questions is, any ideas what could be going on inside of there?
I'm curious cause I'll only have 1 morning to take it apart and put it back together so I'm wondering if I should just get another stock trans to throw in or if anyone has an idea of what part could be going out.
My mechanic friend's boss said he thinks is could be a trans support bearing?

I have a '96 gt 5sfe 5speed...anyone got a trans near maryland for me? haha


Thanks ahead of time for the info!

Could it be a bad wheel bearing possibly? That thumps and goes right along with the speed as well.

doubt its the wheel bearing, they dont really thump...

what you need to do is jack the front up as much as possible and take a ton of pictures for me to see whats going on. then i can try to help.

also in neutral jack the front up and turn the tires manually, see if the noise is still there.

[Rymaster]

Yea the noise is there if I manual turn the wheels by hand, only if i turn them really fast though, which is probably equal to only 7-10mph roughly.

The driver side axles has play up and down it almost seems, like its not fully clipped in but I remember clipping it in fully when installing it and the car drove fine for awhile like i said.


Only thing that seems not normal to me is when I rotate one wheel, it takes a good 2-3 inches of turning before the transmission catches it and turns the other wheel.
Is that normal?

thats normal for the differential to turn the wheels like that...now you mention the drivers axle, its entirely possible that it did not pop all the way back in. there is a snap ring on it and if its not all the way in, it will fall out. its not like the passenger side where it slides right in, you need to use a hammering action to get it to pop in.

Try to pop it back in again, you might have not had it all the way in the first time.

True, but if that is the case, I would think the male end chewed up the female end, which would mean the trans has to come out anyways

Without a limited slip the car would not move in gear if the cv shaft wasnt in the differential. So it cant be the axle being loose, plus all the gear oil would leak out and how do you not notice that

Bringing this problem back from the dead. Going to tear the car apart soon and see whats going on inside.
I want to fix the car so I have something to drive around while I install stage 3 parts on my WRX.

Just make us a good video showing the problem as best as you can. That would really help us help you.

I'll be sure to update! should be taking it apart this week
