Shaking of the car. HELP!

[Toy_Dreamer]

So when i get up to speed, lets say faster then 45 my car starts to shake. after a while like 1 minute or so, it goes away...

Any ideas? Im in need of some help.

The first thing I would do is make sure your tires are properly inflated, then swap the front and rear tires. See if the vib moves or changes when you do that.

Your entire car shudders? Or a vibration in the steering wheel?

Some things i would check:
1. jack up car and spin the tires. look for bulge in tread or sidewall or wheels (steel) that have been bent out of true.

2. Check your engine mounts. Block all the wheels with bricks or blocks of wood, get a helper person, park car where there is nothing to hit for a long distance. Put car in drive, set emergency brake, have the person hold the brakes down. Rev the engine (blip it) in drive, and watch the engine. If the engine moves alot, maybe your engine mounts and/or transmission mounts are broken and need replacing. (Compare to a car with known good mounts if not sure what you are looking at).

3. Bent cv drive axle shaft? Not likely but possible. The CV joints could also be broken inside, maybe a ball bearing has cracked or something. Jack up car, rotate wheels, watch cv drive axles turn looking for irregularities.

4. Warped brake rotors or drums. (But you would feel it on applying the brakes and you didnt mention this.)

5. sticky brake calipers or wheel cylinders? (again, not likely the cause of your shake)

6. Front or rear wheel bearings about to go bad.

By the way, this is under the wrong generation. It's a Gen 3, oops

That happened to me before but I only came to find out a few of my lug nuts were somewhat loose.

Check your tires.
- If the tread is deeper on the edges than in the center, the tire is over inflated.
- If the tread is deeper in the center than the edges, the tire is under inflated.
- If the tread is deeper on one side than the other, have your wheel alignment checked soon.

Check everything in the suspension too, blown shocks can give you a rough ride.

mk, i'll take a look at the, that might be the problem.

Just do some checks like these

If still no good go see a dealer about balancing and alignment.

Likely causes:
Bad tire (bubble, etc)
Out of balance tire
Bent wheel
Bad wheel bearings
Loose axle nut

Less likely:
Worn ball joints
Worn bushings
Bent suspension parts
Bad axles
Worn struts.

If you're lucky it will be a bad tire. You may not be able to notice it visually. Rotating the tires and noticing a change in the vibration is a good indication of this. Most of the tire shops will evaluate your tires for free.

If it is the tire(s) get it fixed. If you let it continue it will damage the rubber bushings of the suspension and that is expensive to fix. If it isn't your tires then it is likely the suspension IMO. Quick check is to just look at the bushings to see if they are torn or broken and flex the ball joints to see if they wobble.

First things first. Check the tires.

im guessing it might be a bad tire. I wil lhave it checked out tomorrow or so.

I had the exact same problem. It turned out to be a bad CV axle. After replacing the axle, the problem went away.
