Ok heres my probleem I have a low rumble@and after 2500 rpms. It sounds like its comming from the center of the car. It does not matter what gear Im in. after 2500 It getts louder but only happens durring acceleration after I get off the throttle it goes away instantly heres what I have done to try and remedy this. new tranny mounts , motor mounts not new but they are fully intact(I pulled them and tried to pry the rubber apart no luck) new U joints freshend rear diff, and i pulled an exhuast off of my other hatch that has all of the right clearances(at least 2 in from anything) crawled under and looked for rubbing or any sign of bashing but no dice. All of my cvs are good, the engine valve covers are 2.25 inches from inside frame rails , so its centered in the hole, mounts are tight Tranny replaced but I got it from a jy but seems solid in all gears smoothe shifting, replaced all of the linkage rubber for fwd and tranny so no clanging from them Please help She sound like shes comming apart LT oh yea new ball joints and wheel bearings, struts ok

Check all your wheels to ensure they have the wheel weights attached and that there isnt extra mud/snow caked up in them; inside and out.

Hey thanks, But I just put new pugs and tires on and theres no mud/snow anywhere. And this problem happened before wheel swap no change.

 

 

 

any further thoughts? LT

I'd still check them My wife's car has thrown 2 now for no apparent reason.

 

That's a single piece drive shaft right? So no center carrier bearing to worry about?

 

Tough one here! *ponders*

Hey thanks Morgan for the input checked all the weights their all there. this problem has been here for a while thru three diffrent sets of wheels and tires

and yes solid diff no carrier ( that is until I get my 5speed in and talk Qman out of his custom driveline ha ha ha

 

ok back to the noise it seems to be there even when I rev the engine above 2500 rpms its just not loud enough inside the car while driving until I accelerate over 2500 rpms in all gears also I can feel it in the trans Piolet bearring ?or main bearings in rear of crank? maybe fly wheel ARGGG any input would be SWEEEET!!

 

 

Thanks LT

If it is only engine speed related (not road speed), and the noise disappears or gets better when your not accelerating, im afraid a crankshaft bearing is a possibility. Could also be an input shaft bearing in your gearbox. Does the vibration occur when you rev the engine on the spot with the clutch pedal depressed? If not, the gearbox is the most likely culprit. If so, an engine bearing may be causing it.

An out of balance flywheel would be noticable whether you are accelerating or not, so its probably not that.

Thanks for the intel looks like Im pulling motor and gear box today Thanks again LT

that is until I get my 5speed in and talk Qman out of his custom driveline ha ha ha

 

ain't gonna happen. It's waiting for me to get another hatch. Same with the roll bar.
