Noise/Vibration after installing axles.

[c7reed]

Hi first off i wanna say this site is great, lots of good info! Now i have a problem and im hoping someone can help me come up with some ideas. My car has about 75,000 miles on it M/T, the outer boots just recently split open and so i changed both, i actually had a local shop do it at the same time they aligned it, after they were done no more popping and the car drove straight! Awesome! the only problem is now im hearing this kinda of like vibration/grinding when my motor is at 3200 RPMs in any gear. Im totally stumped, im gonna take the brakes off tomorrow and check them because they are squeaking but i know this other noise has to do with my engine/tranny, its only at about 3200 rpms in every gear, all other rpms=no noise. Has anyone experienced this or have any ideas. For one im going to change the tranny fluid to Amsoil 75-90 GL4. When they changed the axles i think they changed the fluid and ive never changed it, i bought the car with 39k. Any ideas would be much appreciated. Im pretty mechanically inclined especially with old chevy stuff but new to the 4 cyl and man tranny. im thinking old fluid finally being changed messed with something or maybe a bearing. Funny thing is i hit the break while still accelerating at about 3200 rpms the sound/vibration goes away. It cant be on the outer of the tranny though because that would be a certain speed not a certain rpm. Thanks for the help.

Not that I think it could affect the vibration you have, but the spec is 75W/85 GL4. TSB changed it for replacement fluid on manuals all the way back to 1996.

Thanks for the heads up on that fluid, now its 75W/85 even though my book that came with the car says 75W/90 (API GL-4)? Thanks for the info

I just had my front right axle changed due to a torn CV boot and I have the exact same problem. There's a booming sound and increased vibration at 3,200RPM, no matter what gear I'm in. (I have an '01 Elantra, M/T.)

Did you ever find a resolution for this?

I replaced my driver side axle with a GSP product from Advaced Auto and had a similar issue. I would get vibration when accelerating under heavy load (low rpm). I suspected the axle. I just replaced it with a Raxle and fixed it. The GSP brand was not machined concentric and the shaft was rubbing on something in the transmission. I'm glad I fixed it before it did major damage.

I've had this same exact problem for about 1 1/2 years and finally a solution! A friend of mine installed it with a part he got from Advanced Auto as well. I haven't tried this fix yet but it does make sense. Thanks a ton for posting this. Hoping to finally put the 3200rpm vibration to sleep once and for all!
