when im drving say about 100mph then slow down to 80mph my sterring wheel shakes its not my balancing or tracking or tyes as i have checked these what could it be really confused

rjlawlor646

when you say slow down are you using the brakes?

mikekuriger

you're driving too fast.

tastoto

no not using the brakes just taking foot of accelarator

big_mike1979

EITHER ALIGNMENT OR ROTOR OR BALL JOINT ..I KNOW THOSE 3 CAUSES THE CAR TO VIBRATE.
MINE IT USED TO VIBR BELOW 70 AND ABOVE 70 SMOOTH .

tastoto

what ball joint

big_mike1979

The ball joint is in the lower control arm to which the strut is attached to.

to all of you who have steering vibration its your wheel bearings that are loose and need tightening hows that.

jbenz2001

Mine does the same thing when I'm around 45mph.I did repack my bearings not to long ago maybe I didn't tighten them enough.I know I do need rotors cuz my steering does shakes when I press the brakes.will try to work on it tom.can the steering damper,steering box have n e thing to do wit it?

tastoto

i did change my brake hubs to new ones asswell the vibration has gone now

jbenz2001

So I tightened my bearings today and it helped out a lot but I still have aliitle vibration.I check my steering box bolts and also checked me damper.how do I know if my steering damper needs to be replaced.

bobbyjo9

undo 1 bolt.. if you can move it with no resistance it's toast. Honestly though if you havent replaced it's most likely bad.

jbenz2001

Yeah its never been replaced,I'm on it!

jbenz2001

Found out that the vibration was due to my rear spacers,to bad I ordered the steering damper already.so I guess that's the next step for better smoothness.

I have the same problem and my mechanic told me it's the suspention springs that need to be replaced since my car has been lowered and it's not with the original springs.could it be that causing the wheel shaking?

dlbehrns

suspention springs???? that makes no sense what so ever. Also check out the steering damper. Its like a little shock absorber on the idler arm. an often overlooked fix by MarcusF, the steering box can loosen up and the mounting points/bolts are on the inside of the left wheel. remove the wheel and you should see them. I remember seeing a pic on this forum.

dlbehrns

strut is attached, NOT Big Mike, our cars do not have struts. they have control arms, ball joints as you said and shocks. struts as they are commonly referred to are McPhearson struts where the shock, spindle and spring are all one piece.
