When I am going over 70 mph the steering wheel starts vibrating a little bit. I put brand new tires,changed the rotors and the pads but the vibration doesn't go away.
I would appreciate any help or advice.

 

could be lower control arm bushings, maybe bent rims, steering shock maybe. bent axle shafts.

 

It could just be a simple wheel balancing. Experienced the same thing over 110 KPH. Tire dealer was telling me to replace all four tires. I refused and just asked for a wheel balancing. And now, it drives to 140 KPH without vibrations. Hope this helps.

 

When you say wheel balance- do you mean the front wheels balanced?
Because I have put new tires in the front and they are balanced.
Thanks!

 

To chassis221
Thanks for the info but I will need more of your help.
How can I check to see which one of the following could be the problem of the vibration? I am pretty sure it is not a bent wheel rim .
Also, when I am making a right turn ( very slow speed 1mph) I can feel the steering wheel going almost by itself to the right direction. IS this OK?
Because on the left turn it doesn't do it.
I would appreciate your help.

 

it is possible that the new tires werent balanced correctly could be off alittle bit. if you got the tires at walmart or costco or something like that those guys arent very good and the equipment might not be too good also. but if your sure that they are good i would check the steering shock it helps to absorb some wheel vibration and they do go bad alot. the shock is on the center drag link something you can do yourself ,2 bolts thats it. that could help your right turn issue. lower control arm bushing are a real common issue that can have different effects on steering and alignment. when they go bad the whole lower control arm moves in and out way too much will cause increased tire wear and some side to side swaying of the car. you maybe need an alignment also could be related to your right turn issue.I got to go to dentist be back later.

 

I really think that this problem is a wheel balancing and alignment. Those faults that you've mentioned were exactly what I experienced UNTIL I had the front wheels aligned and balanced. Just a tip, I had to stand in front of the guys while they were doing it. I've got nothing more to add to this query as it seems the effort of bringing it in to have it aligned and balanced is shorter than spending time chatting on what could be the fault.

 

I once (on another car) had a "shimmy" when I applied the brake. Replacing the rotors and pads would not have fixed it (for long). It was actually caused by a Brake Caliper that was dragging and causing the pads to warp the rotors. So in this situation if I simply replaced the pads and rotors the problem would have come right back. I needed the Calipers rebuilt.

I have a similar problem with my 2001C 200 TDI wagon. There is no vibration at any speed when driving, but when I brake, the steering wheel vibrates. Is it the brake caliper. The car has only gone 50 000 km.

 

Hey MVH,
That was my first problem. When I was braking I could feel vibration in the wheels and in the steering wheel also.Your rotors are warped.
The solution is : new rotors and new brake pads. I would recommend to replace all four. I did that and no vibrations when I brake now - only smooth stopping.
