My car still shakes like crazy at 70 or so mph. I got new tires and got the car balanced and rotated already after I first discovered the problem. It went alway for like a week and now it's back. What could it be, alignment?

My car is stock.

 

What year is the car? miles??? Just so you know when asking a question the more info you provide the easier it is to respond.

It could be your axles.

Is the shaking seem to go away a bit when gas is applied, and the shake more violent when coasting?

 

what exactly could the problem be with the axles? I have the same problem, and narrowed it down to the axles, but i looked at them the last time my car was on a lift, and they axles' boots, joints are all good. I am very curious to learn more about this as well. WHat is it with the axles that can cause this?

 

my car is shaking like hell now. but that's b/c when i was trying to change out the CV drive axles (seemingly easy job), we fukced up the bearings on the Intermediate Shaft when trying to get the Inner CV Joint housing from the driver side off.

so i'm pretty sure all that's wrong with mine is that I need to replace either the bearings in the intermediate shaft, or the intermediate shaft all together.

and yeah, it does seem to shake even more when coasting (and in gear). if I put it in neutral and let it coast, it rolls perfectly. so it's gotta be my drive axle.

but i don't see how anything can go wrong with you guys driveaxles if you didn't do the dumb shiit i did when changing the drive axles out. I beat like hell on the Inner CV Joint housing that was seemingly welded into the Intermediate Shaft. The thing should've just popped right out like the Passenger side did. But something must've gotten messed up with the spring clip or something. I mean, it had been 165k miles on those driveaxles so all kinds of stuff could've gotten into that joint and welded them together if the seals or something went bad. I mean, we do get all kinds of snow and salt on the roads here.

 

My car only started shaking recently. I was missing a hub centric ring out of my wheels, and it was up front, so i know that that can cause vibartion. I replace the missing ring ($2 fix). But that didn't fix it, but it helped a bit. THen i got new wheels and tires, put them on, the problem got 100 times worse! So i thought that maybe the balance of the new tires and wheels was off. I took my car to get the tires re-balanced, sure enough they were a little off. That was fixed. I then got an allignment, just incase the toe-in angle was off in the front, which again can cause vibration, nope, still had vibration. I get it mainly at high speeds, but i feel it all throughout from about 15mph on up, it just gets worse as you increase. It's a lot better now that i did everything, but it still does it. Funny thing is that my axles haven't been touched in about 6 months, and i only started having trouble in the past 2 months or so. I looked at my axles a few days ago when the car was on a lift, nothign wrong, no seals broken, seems to be just fine, no boots or joints bad. but the damn vibration is still there, and i can't figure it out. I have ruled out everything except for axles, but can't see anything wrong at all.

Is there something else i might be missing that can cause vibration? What about something to do with the steering rack>? I took out my power steering 2 years ago, never had any problems. BUt even if that was the case, i don't understand how just putting brand new tires on could make it worse, even when they are balanced. The tires are not out of round either, no defects, and the rims are perfect, no dents.

I'm lost, but i'm living with it lol

 

Alright, it probably depends on the shake. I have an integra and replaced the front axles because of the following shake:

I'd be driving at 50 or above and while the gas pedal was normally depressed the car would start to shake. This wasn't just the steering wheel. If I let off the gas it would go away, or take it out of gear. Turning right showed more play than turning left but had both front axles replaced to fit it. But that was a car shake.

If it's a wheel bearing you should have some noise from the front of the car... sounds like tire noise but louder. A wheel bearing can also make you car shake when braking. I'm assuming that it can do it at high speeds also but should be in the steering wheel and in the brake pedal.

 

broken motor mount maybe?

 

The motor mounts shake at a stop right? At least that's what some friends and my mechanic confirmed.

 

they could shake at any time... depends on the nature of the break.

 

Your axle assemblies are clocked and balanced as an assembly. If you disturbed the clocking between segments or bearings, then you most likely have caused the source of the vibration.

To correct this, you must disassemble "the CV joint" you had apart when you messed with bearings, and turn either shaft end 120 degrees, and reinstall in that position and test drive.

The good news is you only have three ways to screw it up, provided you didn't take the bearing yoke off the main shaft or anything. If you had the yoke off the shaft, then the number of possible errors are equal to the number of splines on the shaft times the number of yoke bearings. If this is the case, good luck. If you only separated the main joint, then it should be easy to fix.

Let us know how you did.
