Steering Wheel Wobble?

[Tricky-Ricky]

You mention that it improves when loaded up during cornering, this would indicate that its more likely to be a bearing or suspension issue;)

That's what mine does aswell. It doesn't wobble all the time.

My suspension and bearings have all been checked are seem to be fine

I'd see other symptoms though with that? It just passed an MOT with no advisories so I'd have expected them to pick up a wheel bearing issue. There is no wheel bearing type noise either. Suspension... wouldn't it get worse the faster you went rather than drive through? I dunno though. How can I test that? Thanks.

Rear wheels can cause vibrations. It does it at speeds not like the fronts. fronts are in the area of 60 mph rears about 90 ish. I am surprised to hear that micheldever weren't all good as I have used them in the past and there used to be a bloke there that was particularly good with supra suspension and could quote the pro's and cons of the lance w alignment settings.

 

 

I get bad wobble under braking and at 50 mph on mine. I am starting with my brake discs. If that doesn't fix it I will look at bearings etc.

Micheldever - you've GOT to use the premier service bay if you've got a nice car, or are sensitive to setup changes. Seriously. The general purpose bays just churn wheels through, just as you describe and they do miss bent wheels - I went in with exactly that, told them I thought it might be bent, but they just balanced it up and stuck it back on with no improvement.

 

When I went back, Andy in the premier service bay was much more helpful and let me see the bent wheel spinning on the machine, showing how far out of whack it was.

 

Doesn't matter if the wheel is new - they can get bent so easily, especially big wheels, and doubly especially if you've got big offset or deep dish.

Go back and get them to balance the rears, that'll be what's causing it I suspect. When one of my rears was out of balance it caused a steering vibration like I said.

[Supragal]

It was the premium service bay. The man I shouted at last time went and washed his hands first.

 

I will get somewhere else to do the rears, it's too far to go just for that.

 

Ark, I will see if the rears are bent then. I will be annoyed if they are!

Rear wheel imbalance will NOT cause steering wheel shake. What rims and tyre sizes have you got Rosie? Do the wheels have the correct size spigot holes for the Toyota hubs, or do the use (spit...) adaptor rings? You haven't got wheel spacers, have you? It won't be the OE hubs that are out of balance. Cheap none OE brake discs can be well out though.

 

Most likely causes of steering wheel shake, after a proper and correct wheel balance, are:

 

Rims with wrong size spigot hole.

 

Rims with wrong size spigot hole and totally inadeqaute plastic spigot adaptor rings.

 

Rims with wrong offset.

 

Rims that are out of true, either radially or axially (very very common on bling cheap wheels, some are a mile out)

 

Incorrectly seated low profile tyre.

 

Rims with none stock offsets, these can be only half a gramme out on balance yet give shake due to gyroscopic precession (an imbalance well off the centreline of the hub).

 

Bolt some stock wheels and tyres on and see if the shake goes away, unless it's disc imbalance I'd bet it will.

Thanks Chris.

 

You won't be at all pleased to hear my answers though

 

What rims and tyre sizes have you got Rosie?

Aftermarket, 18x10 and 18x13 SSR Decoltes... so not cheap by any stretch, but very aftermarket. Envy car was running the same wheels, I don't believe they had any issues so I have elimintated the fatness as a cause initially.

 

Do the wheels have the correct size spigot holes for the Toyota hubs, or do the use (spit...) adaptor rings?

 

Errrr I presume they are correct... I just take them off and put them on like any other car wheel there are no extra bits...?

 

You haven't got wheel spacers, have you?

Hell no.

 

Cheap none OE brake discs can be well out though.

I do have aftermarket grooved discs. They jap owner fitted them, and they haven't changed, this prob is new to me having it back after 4 years. Based on the rest of the car they wouldn't be cheap ones. So it's a maybe but I think unlikely at this stage.

 

Scooter has kindly offered to let me use his wheels to test this, hopefully on Friday.

 

If it is the wheels, what do I do then?

Now you know the answer to this, you just don't want to face it, do you?

[Ian C]

Drive it into a wall hard backwards and claim on the insurance, while leaving the engine and bits undamaged for other Supras?

Chris, if I could put the whole car back to standard I would, or not even stock, just as it was when I got it. Minging colour but right now I wouldn't care

 

I couldn't put stock wheels on it with a wide kit, I'd never sell it!! lol

[Chris Wilson]

Have you got adjustable dampers? You could put urethane bushes in the top and bottom wishbones, and adjustable (good quality) dampers on the front, that would proabably fix it, but first you MUST get the tyres off the front rims, and get the rims checked for accuracy, perferably on a lathe, and it will have to be a biggish lathe, or perhaps on a wheel balancer.

[Supragal]

Thanks Chris. We will see what the stock wheels tell us, then cross that bridge when we get there. Might just be something I have to admit to in the sale.

Any update on this??
