Wobbly shaking steering and pulling to left

Recommended Posts

Car 535d lci

Had this problem when I first got it over a year ago so I put brand new oem ate discs and pads all round. Had wheels balanced and hunter wheel alignment done

The guy could not get alignment perfect had it done twice. Anyway the shaking when braking was solved but car still pulls to left

Now the vibration/ steering wobble when braking from over 70mph is back. Under 60-70 there is no steering shake wobble only after 60-70. I recently had front tyres changed and the balancing was 0 5 as the guy said it could not be 100%

The steering is not really vibrating under braking but is more moving side to side. Visual look at tension bushes seem ok

Any help guys

Sounds like you have two closely-related issues.

 

I'd take the car somewhere else to get it tracked properly.

 

They're not difficult to align, quite the opposite. 

The problem is the people using the laser-guided tracking equipment...!  I'll admit, it's a bone of contention for me...!  :lol:  

 

Seems like most tracking places don't have a clue what they're doing & blindly rely on incorrectly used equipment to set the car up wrong.

 

It's also possible that the thrust arm bushes are worn after all, but personally, I reckon a lot of 'shimmy' issues can be easily rectified by freeing-off slightly binding front brake callipers.  Works for me!

 

Brake callipers binding can also be a cause of steering pull.

After replacing the discs and pads the shaking went

Wobbly wheel was there but not as much

I was recommended to go to someone with a hunter machine so went there and they charged me £90 for tracking and balancing

If they had trouble getting it right the first time could you have suspension bushes wearing out.

 

Also change the tyres they can be a problem

I have changed tyres last few days

The pull is very slightly less but still there along with wobly steering. I have a set of 17" se wheels of they fit I can try them see if the problem goes or not

My car has vague steering on high speeds - doesn’t feel too stable. Got it checked out on Saturday while doing my service; they noticed slight play in the steering rack. Had all the bushes checked but no play in them.

 

Strut top mount baring perhaps?

 

It’s all a guess game and you pretty much covered all the usual suspects. I can only suggest you take it to a BM specialist (if you done so, then somewhere else for a second opinion) and have them take a proper look at it.

What's the best way to check for calipers binding ? When I jacked both front wheels up they spun freeley

 

That's how you check them, so yours ain't binding!

 

Sounds like a suspension geometry issue. 

 

I don't see how the top mount can cause a pull on the steering, unless it were really bad, & then there'd be other, more drastic symptoms...

 

If your new tyres are non-directional, it could be worth swapping the wheels left to right to see if that makes any difference? 

At least you'd be eliminating a potential cause of the problem.
