Alright so here is my situation. I have a rumbling sound that occurs on a right turn only, and only when I give throttle. I am able to take a turn quickly when not on the throttle and the sound does not occur. I thought perhaps it was a wheel bearing, but my mechanic said it wasn't that. I had both of my CV shafts changed as well as a new spindle assembly (on passenger side only) (bearing, ball joint, etc). I can make a left turn and get on the throttle and there is no issues, only on a right turn while on the throttle.

The sound is more of a rumble noise. A wheel bearing is a squealing sound.

I can't seem to figure it out and it is really bothering me. Is there any suggestions on this?

UPDATED:

I am going to try and add a little more detail in hopes that someone can help me out here.

I originally took my car to my mechanic for this rumbling sound. I thought it was a wheel bearing. I got a call from him and he said my wheel bearing is fine and it sounds like something with the transmission. I took it to a transmission mechanic and he said my transmission was fine. He said my passenger side CV shaft was done so he changed that. $500 later and my problem was still there.

It has been bugging me so I did some research on what bad CV shafts symptoms are. Sounded exactly what was wrong with mine. So I took it back to the mechanic and got him to change my driver side CV shaft. Still no luck and back to where we started as well as I have an added sound now. Perfect, just what I need.

So my problem in as much detail as I can. This rumbling sound (as well as sometimes like a clicking type sound) which only happens on a right turn and when I am giving gas. It doesn't matter what gear I am in or what speed, it will still make the noise. When I am at a slow roll (15-25 km/h) when I put it in first I feel/hear a clunk type noise. The sound is only apparent while going through the turn and as soon as I straighten out the wheel the sound goes away. I can also feel the roughness in the steering wheel.

Since my driver side CV shaft has been changed I now get a new sound. It happens after 6000 rpm and sounds like a bom bom bom type sound. You can hear the sound I am referring to in the video near the end. If I downshift so my rpms are above 6k rpm I can hear it as well as if I take it up to redline I can hear the same sound, but not until after the 6k mark.

I really just want this fixed. Could it be my differential? If it were my differential I would be able to hear it all the time correct? I am stumped and looking for some advice. Incase anyone was wondering, amsoil transmission fluid is in there.

Vid 1- I am just manually moving the shaft back and forth...is this how it should sound or does it sound like bad news?

Vid 2- It is hard to hear the sound I am talking about in the video, but is very loud in person. Near the end of the video you are able to hear the bom bom bom sound I am talking about.

For the fellow canadians, if anyone thinks they could help me out I am located in Mississauga if someone is willing to help me!

do you feel anything in the steering wheel/chassis when you hear the noise?

where does the noise seem to be coming from?

does the rumbling seem to change based on speed, or engine speed?

like does the rumbling sound the same at, say, 20mph whether you're in 2nd or 3rd? or does it change depending on what gear you're in (higher pitch or faster in 3rd)?

i'm just trying to ask questions that should help everyone figure it out

i'm not 100% sure if i'll be able to diagnose it, but i figured the more information we can get the more likely we are to give ideas

i'll keep trying to help you diagnose it where i can...i know it sucks not to get a response, so maybe with some discussion we can either figure it out or someone else will chime in with the extra information

well since the noise doesn't change based on gearing, you're right...it shouldn't be transmission or engine related (you'd expect it to change with either)

now since it's a rumbling noise that's dependent on taking a hard right than you'd have to assume it's something on the driver side that would be worked more, like you said

i'm almost 100% sure you've done this, but have you double checked your lug nuts are nice and tight? (not hand tight/loose). this shouldn't be the issue, but may as well start cheap first.

another thing that went through my mind when i heard this....is possibly axle related? i haven't had axle problems myself but it seems it'd be part of the chain and possibly make a rumbling noise with throttle if there was a problem with one

EDIT: actually, the mounts are a good suggestion too

Ya I'd try to meet with someone in toronto and see if they can help (post in your regional section)

But, the noise you hear, does it seem to be coming from straight ahead of you? It may be your differential but that's not a part that normally (ever?) wears out

It sounds like that could be it from your description though - accelerating through a turn. I wonder if it's just not within tolerances and the higher rpm's kind of exaggerate the problem/sound?

You may also want to post this in the Transmission section for advice specifically about the transmission or differential
