Hi Guys, Im getting crazy steering wobble when reach the speed between 55-65km/hr, it will shake violently and felt like the front wheels about to come off :roll:

Not sure is this a common issue with the st90 and would like to get this sorted out...

I've a vid of it when its happening https://vid.me/q1dw

Check your tyres for deformation or imbalance. shake can also be from worn out shock/strut, brake drum/rotor warpage but the wheel situation is more likely.
So many delays to getting my MB back in order with 993cc & 5 speed transaxle... neighbor issue gone, donor shell up on rotisserie, new sheds on the way.... another project also..

I had bad vibration through the steering in my SK410, turned out to be a bulge in the front passenger tyre.

Sorry I didn't mention I had try on another set of wheels, these current tyres and new wheels has no lumps and rotated the wheels. It still vibrate intermittent around 60km/hr. Where else should I be looking at?

Yep, the next most logical point is tie rod ends and the pitman arm bush.

Can anyone confirm these are the correct tie rods I'm after?

For the pitman arm bush, I couldn't find any. Maybe is cheaper option to change on both side. Is there different between left and right or they are the same.

The second link is a lower control arm, the pitman arm is a completely different part.

Honestly I haven't had much luck buying parts off ebay. Half of the time the part is for a different model, or poor quality. Although it costs more I get better service and more accurate results buying SGP parts through a Suzuki specialist - especially for parts that are unique to a specific model.

When I had steering issues with my van I bought a complete front end bush kit through SuziWorld, which included the pitman arm bush. Be aware that you need a hydraulic press to get the old one out, and insert the new one.
