My steering wheel shakes at 80 km/h and I'm getting worried about it because this is my everyday car ..... what should be the problem ....

 

I lowered my ke70 3 months ago and it is very stiff and i am running in a 13 series wheels with 165/65 tires on it .... is this why my steering wheel shakes?? or something else?? please help me =(

Start by getting the wheels balanced again.

..and an alignment when you get the balance done. Did you get either done when you lowered it and fitted the new tyres?

Hi Michael,

McPherson strut type suspensions are effective, simple & cheap to manufacture in mass produced cars, but do suffer from lack of adjustments, and are prone to shimmy & vibration issues, if everything is not in balance.

 

Camber & castor angles, wheel alignment, tyres, bearings, wheel balance & rim concentricity all need to be near perfect.

 

If mods to the suspension have been made, then the front end geometry could now be out.

 

The other possiblity is the condition of the tie rod jints on the steering arms, and the condition of the idler arm bushing & pitman arm joint.

 

You can check most of this yourself by jacking both front wheels off the ground & wobbling wheels & steering around to see it there is any play.

 

However, like TAZ suggests, having the wheels rebalanced & a wheel alignment done, is a great investment, as part of these services will check all the above mentioned areas that could be the cause.

 

Let us know what you find.

 

Cheers Banjo

Ok thanks taz, altezzaclub and banjo ... So ill just go to the tire shop and have some wheel balance and alignment and lets see if there's any wobbling wheels ....... THANK YOU VERY MUCH GUYS .. :wootjump:

Hi altezzaclub i get wheel balance and alignment when I lowered my car and i fitted with new tires on our local tire shop here in the philippines 3 months ago ....

Hi banjo my friend gave me an adjustable coilover but i don't know if it will fit.. I gonna post some pix later on about the suspension i got from my friend ....

You might have a buckled wheel. Try putting the rear wheels on the front.

Blzbub is likely right if you have had new tyres balanced and a wheel alignment done. Either you had a buckled rim on the back and they fitted it to the front with the new tyres, or maybe a wheel weight fell off, which is a polite excuse for some guy who did a lousy balance job.

 

Hold a screwdriver on a solid object like a concrete block beside a jacked-up wheel and rotate the rim past the screwdriver. Watch to see if the rim moves closer and further away. Do inside and outside of each front wheel. If you find one that is 5mm or more out swap it to the back. If they both check out OK go back to the wheel balance people and ask them to check both wheels.

 

While you have each wheels jacked up try to wobble them vertically (wheel bearings) and horizontally (steering knuckles) as Banjo said. Any play will need investigating.

 

The more you do yourself, the less you have to pay someone else to do.
