Default Steering wheel shake

My car is a 2004 2.7 with 63,000 miles.

I have search the net and the forums finding the exact same issue.

My steering wheel at times will shake quite a bit. What's odd is that it is intermittent. And only at speeds above 40 but there's no rhyme or reason as to when it will shake. It makes no difference if I am in neutral applying power using the brakes etc. It's sort of has a mind of its own.

The problem did start when I put the current set of tires on it. However an intermittent problem does not make sense if it were a balance issue. Seems like it should be on the same sets of road and smooth on the same set generally as well.

The tires are the ones that were with the car when I bought it about six months ago I took them off during the winter. And they are a very cheap set of tires.

Is it possible that these tires on certain roads just cause a bad vibration?

It seems to me that balance and or alignment would be present at all times at higher speeds especially.

My current situation is I could be driving 90 and totally smooth 50 totally smooth than a mile later the wheel will vibrate

Vibrations are usually caused by:

1) unbalanced/damaged tires/wheels
2) worn control arms
3) worn CV axles
4) worn wheel bearings (but that is usually accompanied by noise).


Given the sporadic and unpredictable nature of you shakes, look at control arms first. Any arm with cracked bushing will allow for uncontrolled movement that will result in wheel shakes.

Have you checked your front control arms and/or front CV joints?

Mine had a similar shaking that was a combination of a worn PS axle and cracked control arm bushings. Granted mine had ~155k miles when this happened so yours seems a little young for those problems but it's worth a look.

Here is what one of the upper control arms looked like:


Here is what the old axle looked like:

Wheel/tires don't make sense given how random it is.

Would/could these others be so sporadic? For instance. Yesterday of course after I write this I get one moment of shake at 40mph. Then perfect for the next 20 miles...

Yep, mine was sporadic above 45mph or so. It would shake for a couple of miles and then go away for several more.

And replacing the axel was the fix?

Replacing the axle and replacing all 8 front control arms. That fixed the shake.

you were already told by few people what your issues is.

Dive under the car and look at your bushings and give axles a yank sideways too. If there is any movement/slop sideways, your axles and also suspect (they move along the shaft by design though).

Look up at post #5 where I said that it was. Just get under your car and check it out. It's as easy as taking off one of the wheels and looking around. I even gave you pictures of what to look for.

Thanks for all the input. Took the car to a shop I use. They did not see anything wrong with the axel/arms, etc.. All looked good underneath. Suggested as a troubleshooting idea to have the wheels rotated and balanced. Did this. Problem solved.

Unclear why this would be so intermittent. But whatever.. Have drive about 50 miles with zero shake. Guys at the tire shop also agreed that everything looked solid.

Time will tell but fingers crossed.

This might be too late now. But it could be a slipped belt in the tire itself I have seen and have had it happen to me before. But that's just for your info and keep in mind in case it comes back (fingers crossed)

I'm my own words a tire is made of layers that create the thickness of the tire it self and if they become loose inside the tire it will be out of balance

For better explanation

Let me know if that sounds like something that makes sense

Cheers

The vibrations caused by the individual unbalanced wheels can either be "in Phase","out of phase", or somewhere in between. If the amplitudes are close and the vibrations are "in Phase", then they cancel out each other. This is the method used in timed balance shafts in engines to reduce vibrations.

In your case the seperate vibrations are not timed. This accounts for the vibrations coming and going.

Final conclusion.

Tires were balanced and rotated. Problem was fixed..... But after three days it returned. Leading me to believe the inside of the tires/radial were falling apart.

Had a set of Bridgestone potenzas mounted. Problem was WAY worse. They found one tire was bad and also double checked allignment.

500 miles layer. All good

I had the same issue and it ended up being the tie rod. Changed it and problem solved. $60 total cost.
