Vibration in wheel at higher speeds.

[Nekoni]

Cruising at 70mph on the highway, I'm getting a very noticeable vibration in my steering wheel that's annoying as crap. It only happens when you're going in a straight line and mostly when you're just cruising (it tones down deccel and accel).

I've replaced both lower control arms, both outer tie rod ends, both front wheel bearings, and both front axles minus the intermediate shaft on the drivers side. After all that, I had the car aligned to factory spec and it's still doing it.

I guess this point the only thing I can think of would be somehow something in the wheels or tires unless you guys can figure anything else. The front end feels pretty dang tight at the steering wheel and at the wheels.

Tires are either worn or need to be balanced.

i would say its your tired or rims. in any case one or the other for sure. some times the tires will look fine but inside its not straight.

Go the place you got your tires, or where you normally have your car serviced. Have the tires put on the wheel balancing machine. Besides checking the balance, watch the tire as it spins; either spin the wheel by hand or have the machine do it.

1. Visually inspect each tire's tread as it spins. If the longitudinal tread lines shift from side to side, you have a separated ply or tread. From the side, check for any "bouncing" which also could indicate a separated tread or ply.

2. Put your hand on the tire tread surface as it spins. Feel for any "bumps", bouncing, lumps, etc. Most tires tend to chop or cup on the inside edge (usually due to lack of rotation).

I should add, any reputable tire place SHOULD tell you if there's a problem with one or more of your tires. They make sales when there's something wrong with your car, so they have no reason not to tell you if there's a problem. But for your own surety, you should ask to be present when they test your tires and wheels. If they tell you you can't watch them balance your tires, find another place to do business.

One of my wheels was warped when I had the same problem as you are having. It was on the back when I first bought the car, but when I rotated the wheel to the front my steering wheel shook like mad.

You have Prothanes or solid mounts? My whole car shakes when hitting 80 mph.

wonder if you got a tie rod end, or ball joints ready to give out on yas..These going weak amplify road vibrations also..another area to look at as well (hate to see you suddenly head to the barrow ditch when a tie rod end busts).....

My guess is a bent rim. Next, a tire blister, inner sidewall.

Try to find a place around you that has a road force balancer. It has a arm the comes down and adds pressure to the the rim and tire while its spinning to put the tires under the same stress it would be driving. If its out enough they will actually spin the tire on the rim to match the high and low points of the rim and tire if that cant fix it your going to need either a new rim or tire.

This is a perfect answer. Make sure they also watch the inside of the wheel from an angle to see if it is bent.
