Question: Steering wheel feed back

[Marv02]

Just checking on rough roads CA Freeways I get Steering wheel feed back as in a vibration is this normal for the C4.
I have 16 inch rims 50 seires tires new bushings new shocks.
Not so bad you cant hold on to the steering wheel but you know it vibrating going down the road.

No vibration is not normal. Does the vibration get worse as speed increases?(Out of balance tires-Bent rim-Bad tire)

Do you feel it more in the steering wheel? (front tires)

Do you feel it in the seat or floor boards(Rear tires-Universal Joints-Out of balance driveshaft)

Are your tire pressures the same in each tire. (overinflated tires give a harsh ride) Set them at factory specifications.

Next if the above are not the problem then start to look at the wheel bearings. And don't forget the alignment.

A vibration can only come from something that is turning.

Another check is to get to speed and put car in neutral so it can coast. If you do this see if the vibration gets better while coasting. Also check for the vibration with the car in drive so that the transmission does not go into overdrive (If it does you may have a problem with the transmission overdrive - Check fluid level)

All the tires are new.
245-50/16
They have if I lucky 5000 miles on them.

I rotate front to back and see what happens.

It only in the steering wheel at 70 MPH. The trans is POS I have a new one beening built for me

The U-Joints are new

OK steering wheel at 70.

Does it progressively worse above 70?

I think you should have an alignment shop check the lower ball joint and the inner tie rod assy.

After I did this my front end was much smoother.

Don't trap yourself in a box by thinking since the tires are relatively low mileage that they are all right. Tires can be fine one second and bad the next. I personally have had to have the tires on my vette balanced every 1 to 2 thousand miles until they finally took a set on the rim.

At this point all you can say for certain is that something is causing a vibration, and you need to recheck all the items that can cause that to happen. You simply can not assume that any part of the suspension is good even if you had it replaced a week before your vibration started.

Oh and recheck all the nuts and bolts you removed to put the new parts on the car you may have forgotten to tighten one of them down.

Finally If you have an FSM there is a really good section on the suspension and how to diagnose vibrations in the car.

I had the tires rebalanced and had the aligment done.
Drives great now.
