My steering wheel is shaking/vibrating at highway speeds. It does not happen all the time. It comes and goes after turns. Sometimes it is perfect and sometimes vibrating like crazy. I have no idea what is the reason of that.
I did: WHEEL BALANCE, ALIGNMENT, TIE RODS, BALL JOINTS, WHEEL BEARINGS, ROTORS and TWO DIFFERENT SETS OF WHEELS WITH TIRES. None of that helped. Why is it vibrating??? Why only sometimes??? Did anyone have a similar issue and solved it???

 

for the love of god I hope you find out

I have the exact same prob on my xb for the pasy 4 years

I have changed the wheels tires shocks springs aligned checked wheel bearing and balanced and it still happens

It happens at about 75 and then will be perfect and if I hit a bump or make a turn it will start again.....Sometimes though

eliminating all the things I have changed and what the evo and xb have in common I think it would have to do with the axels

have you modified anything else

 

Have you checked your tires for slipped belts? That can sometimes cause the symptoms you are describing.

 

i have same problem.. just cant figure it out..

 

It is not the tire belt. I have two different sets of wheels with tires. The problem happens on both. I tried both of them on my buddies EVO and everything is OK.

 

Try your buddy's CV axle next time.

 

i have so far replace my front axles. new struts and mount.. at -1 camber shaking is less. -2 camber its terrible. both front bearing. new rack bushing. energy suspension control arm bushing.. .. problem still happens with stock wheel and dunlop snow tires and same for rota p45r and nitto 05 tires. toe is 0 in front... both set to wheel at are road force balanced. .. my problem started happening after i did a complete brake job.. i replace my brake line. stoptech rotors and ds2500 pads.. no shaking and vibration while stopping.. i did found out that stoptech rotors were out of balance.. got new ones from stop tech.. same problem.. caliper pistons are free. no binding when to compress them.. caster is at factory setting.. sub-frame is tight.. nothing i can see wrong.. ..

 

Wow. And it's also random? That's baffling!

 

random.. can start a low as 5 mph.. steering goes l to r .

 

Could it be a loose steering rack?

This would explain the Sometimes Problem

 

no play in rack... bushing a are new..

 

anyone???

 

well u replaced the struts and mounts.... are they torqued to spec....u also said you replaced the wheel bearings...did you replace the hub with the bearing or reuse the old ones....my guess your possibly pickin up road vibrations, some are not as smooth paved as others...ive had a similar issue to yours, so far have replace both outer and inner tie rods to correct it...start checkin to see if maybe you have worn out control arm bushings....??? maybe broken sway bar end links or something...
good luck thats my 0.02

 

my car was doing this too until i got my new rims.

 

I dunno, but this kinda sounds like a power steering problem, especially the part about it happening after turns. Could there be something wrong in the rack or pump that could cause this?
