NEW VIDEO/SOUND
Up until tonight I have been going fairly easy on the throttle, I decided to try my luck with an Italian tune-up and went for a couple good hard WOT pulls onto the highway through 2nd and 3rd. Once I get going the wobble and sound goes away (possibly because I'm just ripping and my turbo sounds like an airplane taking off and I can't notice it). Turns out it went well and nothing went wrong or broke but the problem is still the same. Next I decided to try and get a better video of the sound when it is most pronounced and I did have some success.

In the following video I had a hard time picking out the particular wobble sound with my laptop speakers, but then I threw on a decent set of headphones and it's very clear. Hopefully one of you can help me identify the cause.


It kinda feels like its coming from right under my left foot. The front left LCA bushing is slightly torn, that couldn't make this big of an impact could it?

UPDATE

I replaced both axles with new non-reman cardone ones, then replaced the intermediate shaft with a DC shaft and DC driver side axle, took it in for a wheel alignment and everything was pretty much perfect already and all the suspension components are tight and in decent shape. The motor mounts appear to be in good condition and when I try rocking the motor back and forth there is very minimal play (the upper driver side mount shifts a couple mm side to side).

For the most part the problem occurs only when I am accelerating in first or second gear from about 3k rpm to about 6k. I don't seem to get any sort of wobbling or clunking when moving at a constant speed or during high speed acceleration. The problem is more pronounced when going uphill. Also, it doesn't seem to be as bad when the engine is cold.

-----------------

This particular problem of mine started about a week ago when I made the mistake of not slowing down enough to go over some pretty hairy train tracks.

The crash of my front subframe onto the ground was pretty gruesome and almost right away I was left with a kind of clunking sound that only occurs during acceleration.

I cautiously got the car home, got it in the air and took a good look around too see if I could identify the problem. It looks to me like the passenger side axle is the culprit as it appears to be wobbling on the end that goes into the tranny.

Maybe this the result of what was an old differential that was starting to go bad and the impact jarred it to the point of no return?

It's a 92 Integra GS with a turbo LS/VTEC and the original YS1 transmission.

The horrible sound only seems to occur during acceleration, under load.

In car acceleration (difficult to hear the sound in question, I will try and get a better video later).



Thanks for any help or input you can provide!

check your mounts make sure there good. or at least in some normal condition. pull the inner cup and see if anythings loose. you might have busted something inside the tranny. hard to tell if you cant see in it but i could see the wobble a little. also plz be carefull that close to rotating stuff.

I would check your mounts, but like Blackhalo6 said. It sounds like something let go in your tranny, I would just upgrade to a hydo Type R tranny and call it a day.

Maybe get a video of the sound itself?

I added a vid of a short bit of moderate acceleration but the sound is quite difficult to pick out of it, I will try and get a better one later.

The mounts seem to be fine, my understanding is that if it only happens during acceleration that its more than likely directly related to the axles, correct?

I'm really hoping that it's just that passenger side axle that might need replacing as I am on a starving student budget at the moment and can't afford the cost/time of dealing with a new tranny. When I look closely at the axle spinning in the tranny it seems to be pretty uniform (and comparable to the other side connected to the half-shaft), whereas the boot on that side of the axle seems like it is not perfectly straight.

Grab the axle and try to move it around to see if it has play. In and out of the cups is normal btw.

ParadoxTeg

No play other than minimal in and out.

Also, it seems as if the problem doesn't occur when the car is cold. It only happens after it has warmed up. Maybe this narrows down the problem?

After reading through many similar threads on various forums, I feel like there is a good chance it might be the inner joint on the passenger side axle that is the culprit. Anyone else had this problem before?

Blackhalo6

did in my old escort after someone ran me off the road. it was from my ball joints being almost completely separated.

See first post for new info.

take it out and try re-seating it ? I know it's a pita to do or pay 100$ and get a new one from a parts store ?

ParadoxTeg

I've tried two different new drivers side axles and have a new passenger side axle in right now. Unless these axles are the biggest POS of all time I'm just not convinced it is the axles anymore.

New video up.

It may be the diff. It's definitely something internal in your trans.

ParadoxTeg

How are you so sure? It feels and sounds like its coming from the left side of the car, not the trans...
