Hi guys,
i got the above.... obviously when i get above 70mph it's on my friends' private track ::)
the shake is distinctly between the speeds of 70 and 85. before and after these speeds it settles down. i recently had my alignment done at WIM and i asked the guy... he said that will be to do with the wheels needing to be balanced.
i'm having 4 new tyres next month and will get the balancing done then but do we agree thats what it is? why particularly between those speeds? ???
cheers guys :y

Do you feel it through the steering or the seat?
Its an anti speeding device ::) ;D

Haha or is it a speed encourager as it goes away after 85 ;D
The vibration is both through steering wheel and the whole cabin including the seats

Front wheels out of balance usually shows itself as vibration through the steering wheel at whatever speed, rear wheels out of balance usually shows itself as vibration throughout the whole car. The speed it happens at is purely by how much out of balnce the wheels are. An old Astra of mine shook itself nearly to bits at around 65, wheel balancing sorted it! :y :y

thats what i was hoping as when i get the tyres done they do free wheel balancing... cheers guys :y

It's certainly possible for a wheel that's out of balance to causing a vibration between certain speeds. Easy and cheap way to prove it would be to swap the wheels front to rear, and see if it goes away. :y
Could also be a buckled wheel...
Edit: Must type quicker! ::)

......

I always insist on stick on weights on the inside. Clip on weights just bugger up the paint on the edge of the wheel where salt sits ..... & they look sh1te. ;)

cheers guys. really appreciated :)
on an aside, found this cool video tutorial...... looks very easy with the right equipment :y

Thats the warning system saying you're at V1 Webby, slow down to stay down or foot down to take off! ;D ;)

see if they have these in stock ;D

LOL! Cheers lads.
I wonder.... is it possible to balance your wheels without the funky machine?
-
scrap that just found the how to....

anyone do this themselves out of interest? :)
-
I had this problem a few years ago, and it was just after buying some new tyres! Took it back and they rebalanced all the wheels, but it made no difference.... :-\ Turned out the new tyre were out of shape!! :o After a 'few' arguments they reluctantly replaced them and all was well!! :y
-
That method is "static" wheel balancing and is very inaccurate ... "dynamic" balancing which is done by rotating the wheel at speed is far better as it more closely follows the wheels actual performance.
The best method of all , "dynamic on car" is very difficult (and expensive) to find these days, although back in the 60's & 70's was easily available, it takes into account any imbalance in the hub (in those days only posh folks had disc brakes), disc and even the drive shaft to an extent.
I used to have this done regularly on the rally car but would not pay for it on a general use vehicle, but I would not drop down to static ... a normal dynamic balance is only a fiver or so ... less than a gallon of fuel per wheel .. :(

how do they get imbalaned? i actually only need one tyre (legally) so should i get one tyre and just that wheel balanced or 1 tyre and all wheels balanced? :)

wear, age, curbing .. all will affect the tyre as it rotates, but wear most of all :) The tyre can also "slide" around the rim over time, the forces of braking/acceleration are quite high on the sidewall, this will affect the balance as the tyre has heavy and light points which are no longer in the position when the "old" weights were applied. You can also simply lose a weight..
If you look at a reasonable tyre you will see a small yellow dot on the sidewall ... that is the "light point" and should be beside the valve,... if the tyre has been mounted correctly ... many tyre fitters don't know/understand/bother an just use massive amounts of weight to correct their incompetence :(
HTH :)

cheers mate. that does help! :y
so if i choose to get one new tyre i should still get them all balanced? :)

Sorry I was editing my last !! If you have a serious vibration problem you have a couple of options ... if your spare IS balanced (and it should be) replace each wheel in turn with the spare .. if you find things suddenly get better you may have the wheel with the problem in the boot !!! if that makes sense !! :)

it does mate thanks... so is it likely it will just be one particular wheel (not necesarily the one to be replaced) that is imbalanced? :)
-
If the vibration came on suddenly, IMHO yes ... as it would be more likely to be a thrown weight, if it has built up slowly over time then it could be wear and so may involve more then one tyre ...
But I could be wrong .. only a balance will tell you the truth !!

thanks entwood. thats really useful info.
im defo going to try the spare at all 4 points..... that should give me some more info! cheers mate :y

I'd be examining the wheels and tyres for damage or faults of any kind to start with. Jack up and spin each wheel looking for oscillating rims or tyres, bulges, flat spots, tears or forign objects.
If its just balancing at fault, obviously leave it until the new tyres are fitted as you say. But its certainly not recommended to put total faith in the the word here. We can't see the wheels or tyres. Have a look as a starter. :)
-
thanks Chris. More than helpful as ever. :-) so as well as the balancing possibility it could also de damaged Tyres.
-
Yep, "could" be. Symptoms do sound like balance issue, but a number of things could also cause it. Better safe IMO.

sweet cheers mate :y
any idea on what i ''should'' be charged to have all 4 balanced so i can get a quote and decide whether its too pricey :)

thats the best method :y and I give up for other methods long time ago.. but not cheap..

Only system I have found to work to an acceptable level is a 5 stud balancer. As opposed to the cone balancer more commonly available.
How much? Not sure. My local guys have to re do mine for free as they keep fe@king it up first time around. It's like bloody ground hog day down there.
Ring around I guess? But tbh, get some new ones on there. :)
-
Thrown weights, wear, potholes, buckled/ovalled wheels are all things that can cause vibration at speed.
If only under braking, discs and suspension/steering components worth looking at
