[Mk2 Turbo] Vibration over 70mph

[jamesdoherty]

My steering wheel has started vibrating at speeds of over 70mph - Any suggestions on what could cause this?

Thanks

Wheel balancing mainly...

has it only just started ?.. it's quite possible for the little weights to come off or for muck to get set solid and throw your balancing out.

another cause is your tow in or out to a degree on your front wheels.

warped brake disc ?.. but you'd feel that through your brake pedal when engaging it also..

buckled alloy ?.. whacked your front wheels lately ?
Also Tracking...

and finally... wheel nuts all tight ?
sounds silly but I'm guilty of this one... was VERY lucky the wheel didn't come off !

few suggestions for you to be going on with

[Goldy]

1 more thing....... binding brake caliper.... often overlooked.... If you take your car to a garage to get the wheels balanced get them to spin your front wheels whilst its off the floor to check if its the calipers!!

[CosmosblueMR2]

also if it's a sticky caliper then that alloy will be hotter than the rest due to the friction build up..

i have this issue ,its quite annoying when having to break at this speed, only requiring a firmer grip. anyway im sure i read somewhere that there was a solution to this problem. This was not one of the easyer to diagnose or rectify and the problem i have now is remembering what it was, but i m sure someone said the parts are 35 pound per side, i dont knoe about posible fitting times as i said i cant remember what the parts are, somethin gto do with the hubs maybe?
anyone got a clue on this?
The obvious to check had been mentioned previously.
Check youre wheel weights are still there,
Check your tye pressures
Check the play in your wheels bearings (if u have a stable way of jacking the car up)
Have a look for uneven tyre wear on your fronts.
hmmm

Anyone have a clue as to the 35 quid thingys i was talking about

[jamesdoherty]

Hi,

Thanks for the replies.

I will get the wheel balancing done again tomorrow. I have recently replaced all Brakes, Suspension etc and all was ok, so i am hoping they are still ok.

I hope it could just be that one of the little weights has come off.

I will keep you posted.

Thanks

I've had the same issue for a bit too. irritating to identify the problem as it comes and goes! Sometimes it shakes quite a bit other times not at all. always above 70

Dunno how it can vary so much from time to time..............

Cause it dont happen below 70 i am reluctant to ask the mechanic to go speeding to experience the fault (which may not appear)!!

my car vibrates from 80 +

and becomes unstable - feels like heavy side winds - after 90 +

I have had my brakes checked, balancing, new tyres still there - I had laser alignment done which identifys that my back left wheel is slightly out on tow - which I think is doing it

It is quite scary doing a ton when this happens !

[adam maclean]

Also have this problem. Thought it was the tyres but have recently changed all 4 wheels and tyres and nothing has changed. Had them balanced twice (fronts only) been OK after but started to play up again a few days/week later.

Ive had different views on balancing the rear wheels. Some one told me that above 70 means its the rear wheels out of balance, others that you'd feel the vibration through the car if its rear wheels. Any one confirm/deny this and could it be the problem?

[jamesdoherty]

Got the wheels balanced again - Vibration seems to come and go now over 70 = very strange?

Seems to be worse on motorways than on twisty country roads?

Will keep trying to sort this - i'll keep you posted.

I have same problem. 70+ mph judder. Mines a rev 1 GTi.

I had it with the alloys that were on the car when I bought it.

I got some new alloys fitted and balanced (not because of this problem, but because they were minging!) and had the same problem. Went back to fitting place and they said it may be the spiggot rings. They changed those...

Now the car judders at around 75mph (its the same all the way up to 110).

Lots of people say it may be tracking, but (I may be wrong here) I thought that if the tracking was out, the car would pull to one side (which it doesnt).

I'm taking mine in at month end for a mate to have a good look over it. If no one has come up with an answer by then, I will post the findings

[adam maclean]

Yep exactly the same problem as you two. It is worse some days than others, great going to work today, nightmare yesterday. I don't think its tracking either, as far as I know it would pull to one side if its out. Also ive just had my tracking done and it was there before and after.

[The-Shield]

Well mines all sorted now. I went round to my mate at the garage and he assured me that tracking should not cause the vibration and advised I get the wheels balanced.

He sent me round to a tyre place round the corner and they balanced the rear set first (they said whoever balanced them originally should be shot as there were weights all over the place, I was in the room and witnessed the whole process) and I took the car out for a spin...

The 70mph judder had stopped but as I hit 80mph (private road) the juddering started and carried on all the way to 100mph. At that I went back and got the front wheels balanced, tried again and the car is now perfect... The best thing is it only cost me £10.00 (£5.00 rear, £5.00 front).

Anyway thanks to P.I Motors and Dexel Tyres (formerly Sayers) in Bentley and shame on you Top Gear Performence (Doncaster branch) for fobbing me off.

[adam maclean]

So the shake could be down to rear balancing . Most places have told me that you don't get a steering wheel judder from the rears.

[The-Shield]

I was told that high speed judder is from rear and low speed is from front. Get both sets done for what it costs.

[adam maclean]

Going after work tomorrow.

[The-Shield]

I hope it cures it for you mate!

I was told that high speed judder is from rear and low speed is from front. Get both sets done for what it costs.

[The-Shield]

Either way it worked so I couldnt really give a fook if its wrong. At least there's no judder at all now.

[adam maclean]

had all 4 wheels re balanced last night. Just the same on the way home. Not too bad going to work this morning though. Any one got any ideas what could be causing this if its not balancing?

Could top mounts cause a judder, these are the only things that havn't been changed on the front.
