Steering Wobble And Brake Judder


Recommended Posts

I get a substantial wobble through the steering wheel at around 60mph. It's not so bad at less or more than that speed. Also I sometimes get a judder under breaking, though not always.

I've changed the front pads and disks in case they were warped. I've had the wheels balanced and ensured correct tyre pressure. Still the wobbles and judders persist.

Any tips on what else to check ?

It's easy to spend a small fortune trying to sort this one out. I've been there.

Take my tip. Get the front and rear wheels swopped and see if it disappears. One front wheel with a slight buckle will cause this and it doesn't necessarily show up on a balancing machine.

My GS has been balanced countless numbers of times and spent 4 whole days at a dealer who couldnt work out what was wrong with any of the suspension / steering.

Even tried balancing the wheels on a hunter 9700 road force balance machine ...and a visit to WIM to check the geometry - solved the prob for a while but its back.

Consistent advice seems to point to the non OEM rims I have and the fact the offset is different (35 vs 50) - Ive eventually bought some this last weekend and having them fitted and road force balanced tomorrow.

As the wrong offset alters the geometry im also having a geo check tomorrow too.

Hopefully the end of my woes.

Mine is worse some days than others and particular road surfaces seem to make it better/worse.

By all means get the ball joints and track rod ends checked out but also consider looking for a road force balance machine - they are pretty rare - I have a link for UK garages with one (http://www.pro-align.co.uk/amc/centrelocator.htm) but not Ireland unfortunately.

Go to the Hunter website to see all the reasons why they are better.

Another member on the site had same issues with his GS - and after going to have his road force balanced he was happy as anything. He had oem rims.

Also - If you dont have OEM rims then could be to do with the incorrect offset - but I'll know more about that tomorrow ;o)

Good luck - and let us know how you get on.

Another thing - check the torque on your wheel nuts and ensure they are tightened in the correct order - Lexus wheels have a low torque spec compared to most cars and the idiots in most garages use impact wrenches or dont torque at all so then end up being at ~160 - way above what they should be. This can also cause vibration issues

Anees- that site is poo! Cannot view all items so I have emailed them instead!

I have the wobble myself but my brake disc is warped so will get that changed first!

Anuj you are right, you can't view anything on the site. But they are very quick at replying to emails and Chris is very helpful on the phone. You basically make sure you have what you want, then they send you a paypal link via email to pay (you don't have to have paypal to pay). Front ball joints for my car were £65 delivered, which is pretty good I thought :D

"Apart from the usaul CLUNCK noise when turning" how else would you know that a ball joint is fooked. :unsure: .ive got the same sort of wobble at 50mph + all wheels are fine,all been balanced at WIM..Geo is spot on & had new front Mintex disc`s and pads fitted but still got the wobble`s.. :unsure:

My first GS did exactly the same thing. I went through all the usual checks and found the fault by accident. I had a sticky front brake caliper. I stripped both of them, cleaned off all the muck and put it all back together. Wobble cured and never returned.

I found it when one of my front wheels felt warm compared to the other one after a run home from Blackpool I think. It wasn't sticky enough to cause a pull on the brakes but it did stick on to cause a wobble at a certain speed that I could drive through.

check the bearings, knuckle,hub,and rotors uppercontrol arm, lower ball joints And tell me if you have engine hesitation when you wide open throttle above 60 mph to about 90mph

Mark you are correct, my GS was perfectly fine, then my MOT comes up, so I have check with MOT guys, they told me that Break DISKS & PADS needs to be changed, they changed it, that was the only thing, needs attention & my car passed without any other issue. All perfect.

But now, only, when ever I apply breaks, my steering starts shaking, its not that the car will go out of control, but slightly shaking, but this thing start happening after disk change.

Based on your last paragraph, what you have quoted, that may be my issue as well. but after doing a lot of googling but could not find any definitive guide as to how to do it.

Do you have any information to guide me, so I may also be able to correct this problem.

Thanks

My LS has the Clunck noise when im turning occasionally when parking. The front ball joints were both replaced by lexus by the previous owner about 11,000 miles ago are they gone already then?
