Steering Wheel Shake at 70-80 mph?

[dirkdiggler]

I Just replaced all my shocks and drop links and both Tie Rods on the car.

When driving from 70-80 mph my steering wheel shakes a little but pretty fast back and fourth a very little distance.

If I grab the steering wheel firmly with both hands it seems like I can get the shaking to greatly reduce and almost stop...... then I let go and it comes back immediately.

Any Ideas on this???


Prior to all the suspension work the steering did shake sometimes but only intermediately.

My last wheel balance was last year at about 1k miles ago.

All the bushings on the control arms didnt look cracked or anything either.

Car has 64k miles.

Bent wheel? As in pothole.

My car shook the wheel and rebalancing had no effect but it turned out the tire was cupping a little. New front tires fixed it for me.

start by double checking everything you touched.

I have a similar issue and I got under the car and found both lower ball joint boots have cracks/tears in them. I suspect they have been that way a bit and the ball joints are toast. Iplan to install new lower control arms and hope that gets rid of it. I had the wheels checked and they weren't out of balance.

as someone that has chased down a shakeing that lasted 2+ years, I offer my lessons.

basically anything that rotates needs to be looked at. If the shake is rhythmic and gets faster with speed... it has to be a rotating mass issue.

if it never did it and then you messed with the springs and now it is doing it, I would look at it like something may be loose less likely something bent.

Did they knock off a wheel weight?
all bolts tight?
Spacers?

A ball joint or tie rod damage, it may shake but on and off and not rhythmicly. (ie- not rotating)

My issues turned out to be the spacers.
