Hi guys,

I did a search before posting this thread abt 'on wheel balancing' and the effect of it, but more or less the topics was not spot-on.

Anyway, I'm about to send my car for 'on wheel balancing' to cure my New 3 weeks old Pug 308T vibration issues at 130km/h. I did sent the car to Nasim to cure it but they simple send to tire shop to do normal balancing and alignment. And they charge me RM55 for it. But still the same vibration. Tires are ContiSport 3 and stock standard Rims

Now I want to do it outside cos fed up with Nasim. Have to wait a whole day for simple thing (that didn't even work out)

I google around for On-wheel balancing and there are some issues of Problems after doing this like car engine become not smooth (example Altis after did On Wheel Balancing the gear changes not smooth).

Anybody have done 'On-wheel Balancing' to rectify high speed vibrations?

Thanks for any advice..

Regards

dont worry...no problem... i had done it since new car until now (110k) d... infact, i always prefer to do "on wheel balancing" as it will solve the vibrations @ high speed... infact its get the ride smoother all the way to 180km/h without any steering vibration. as normal balancing from the machine would serve up to 100km only or more (depends on cars). all they going to do is jack up 1 side of your car and they will balance it manually.. (this will take some time for them to find the right spot to place the balancing weight)... just get it done..costs u 20bucks or below... and definitely will solve your problem. try to go reputable shops or pm me if u want to know the shops i usually trust on when doing my balancing... =)..cheers

it's not the speed, on wheel balances also the brake rotors together hence more accurate than off wheel.

imbalance will show at any speed

how bout CVT's gear box ??? will it damage it...sifu's pls help thanks

Why would it damage anything at all?

No prob at all...Even more accurate than off wheel

I'm also interested to know.

If I'm gonna do on wheel balancing, I'm might ask them to use engine power to run the front wheels instead.

no idea, personally i think it's ok, but there has been claims that it will damage the CVT....so just asking for confirmation..

the only thing it damages is the tires edge.

Just to confirm...is this On wheel balancing?



Pictures taken from mybenz.org...thx

meaning someone will be seating on a small cart.

There is one more balancing called High speed balancing too....seems confusing that when google...it is either done on wheel (using engine power) or off wheel (using the common balancing machine)

yes it is..

i think less people do this because the lala chai dunno how to use

on wheel balancing = high speed balancing lo... usually done at 140km/h like that not if not mistaken ... told by my uncle who running a tyre shop.

Thx for all the information...I feel more confident know to send my car to do on wheel balancing....I hope it cures the 130km/h vibration.

Need to google for reputable tireshop to do it in JB. Need experience foreman too.
Hope it doesn't break anything on the car.

Thx again

How about gearboxes with LSD? Coz I've been told before that on wheel balancing can damage gearboxes with LSD since one wheel will be on the ground, not moving while it is being done. Any truth is this?

dont think itll damage the gearbox...and the gearbox may be the least of ur concern coz most likely ur car will lurch ahead and smash everything in the workshop since both tires will be forced to move..

but yeah... my old mechanic said he cant do on-wheel with LSD equipped cars as he needs 1 tire to be stationary on the ground. with LSD....both wheel swill be spinning....fast.

seems legit..how about using the machine mentioned earlier? Is it even possible to do on wheel balancing with both tyres off the ground?

last time i did it at goodyear servitekar at sentosa. maybe can try other branch. my car rembat 170 at highway no vibrations at all, really smooth. kinda scary because steering very light and responsive.

even with the machine the other wheel will still be on the ground..

as for doing it with both tires off the ground.. i did ask... n he still said no....forgot why he said it though

Yes, I've seen them doing at the shop...the shop is corner shop just after coming in from Tebrau highway traffic right?

Oh.. Azbro got urself a 308t... Enjoy ur car man...

yeah bro...about time I enjoy real driving other than sit in front of Home Theater set

Cheers

Just worry it is too small for u n family...

Anyway, 308t is a driver car.. Nice to drive... Cheer...

Well, the rear is definitely bigger than the Vios I had, it should be good another couple of year.

After that, it's time to get another car.

Cheers

may i ask any recommendation of good reputable wheel balancing shop around pj/kl?

Please take note...

Not all On-Wheel Balancing will turn out OK..

Example: http://www.myaltis.com/forum/index.php?topic=3522.0

Doesn't mean everyone say good good means its Ok
Depend on cars or electronic / mechanical systems...some cars are not suitable for on wheel balancing.



So please do some homework or check with the tire shop first before doing anything..you wouldn't want a bigger issues after doing it.
We all know shops will do anything to get you to come back again to earn extra bucks

perhaps the rim itself dented?

u mean the boot space?
mostly ppl recommended on wheel..the reason i dont do it because its more expensive and the got only 1 workshop can do it at my place.

Went to a well establish tire center doing balancing, they didn't have a high speed balancer and say that they do Ferrari, posh, sports Benz off wheel balancing all OK, no need high speed balancing. They also say car gearbox will be stressed during a high speed balancing so they dun recommend it to anyone. So they dun have the equipment.

The result? Become worst! Now the whole car shakes above 110km/h

I think I wasted RM 70.

Now I'm in the shop again

If this doesn't work out, gonna do an on wheel balancing. Wasted a lot of money oledi doing off wheel balancing.

tell them to test drive, before/after balancing and alignment.

good mechanics SHOULD do that.

pls let me know where got shop can do on wheels.

mine, not so sedap at highspeed. e

the shop near my place (selayang/kepong area) does on wheel. however i am very particular on my setup hence i will always get them to do proper job, sometimes even follow them while they test drive

and yeah, i dont get odd vibrations driving around/over 150-160km/h

i dont know what the perks of doing on wheel balancing is. to my knowledge on wheel balancing will damage the gearbox due to the absence of lubrication, because the oil pump is not running when u do on wheel balancing. i always opt for off wheel balancing.

normal balancing and allignment is good enough for most cars. Your Pug 308 THP is no biggie. try these places; GS Auto along Jalan 222 or Sunny Car Care in Taman Sea (look for Ah Wah). I normally recommend Audi and Bentley drivers to go there.

your problems could be due to:

1) use of different tyres
2) damaged susp arms
3) tyre pressure differences
4) camber allignment

on wheel has the extra benefit of balancing the entire assembly including brake rotors.

the oil doesn't go anywhere in the gearbox, it still soaks the gears and will get lubrication

Ok, here are some feedbacks, after going back to the shop again to do off wheel balancing, the supervisor said OK oledi, he said no more pulling to the left because now they did alignment as well. Man, I was thinking. I send the car for wobbling issues and he was talking about pulling to the left. The car was right in front of me and there was no alignment done, and I didn't pay for it too. That Supervisor simply talk crap, he dunno actually what happen.

But I ask him to test the car but didn't because it was raining heavy at the Pasir Gudang highway.

In the evening I took the car for a spin at a short stretch of the NS highway.
I knew sure vibration again....waited for the vibration and it never came. Surprising! I was at 140km/h oledi. I felt a bit of vibration above 150km/h but didn't try faster because I had to exit the highway. Seems like OK oledi

I wonder what they did. While waiting in a Jam at the traffic light, I saw they put a small plastic sheet on top on the windsceen showing what they did. There was a word 'Cross' on it.
So the cross thing worked to solve the vibration issues. I looked at the tires and lucky it was a non-directional tires (CSC3).

Anyway, I happy now. But next time I'm sure to do a On-wheel balancing.

Thx for all feedbacks

Cheers

i hope you know what you're talking about. brake rotors cant be balanced. if its worn out its replaced or skimmed if its warped. and what assembly are u talking about?
as for the gearbox the oil goes back to the oil sump at the bottom.

brake rotors you skim or not is not balanced at all, even small thing like pulley can be balanced for extra smoothness, nonetheless for big brake rotors also.

even if go back to the sump, the gears are still much covered in oil, and if not LSD gearbox spinning one wheel means the gearbox is also spinning hence the oil pump also spins pumping oil to the entire gearbox.

normally they do one wheel on the floor and one on the balancing machine, if both wheels off the ground, ok then the gearbox doesn't spin since the differential is there

hye bro ...can i know where i can get the on wheel balancing ....tq

Old thread but i think it will wear out the differentials, since 1 wheel going 140km/h the other 0, normal cornering the difference between left & right won't be so much. This is why it's not advisable to put on spare tyres for too long on the driving wheels as the wheels will turn in different rotation even on straight roads and wear out the differential oil.

FF car on wheel rear balancing should be ok, FR front wheel balance ok, 4WD better don't.

Driving wheel without LSD tend to spin 1 side 1 way the other side the other way, with LSD, the other side will spin the same way, how fast it spins depends how much is the differential limit, this might add stress to the LSD & Differentials.

It might be safer (for the car) to use the engine to turn the wheels than having a balancing machine turning just 1 wheel. This way the wheel with the balancer will have slightly extra load similar to when a car is turning normally. But make sure you get the drive train correctly as doing so on a 4x4 will just mean the car is going to run into a wall.

For permanent 4WD all 4 wheels are inter-locked together with the more complex 3 sets if differentials, so spinning just 1 wheel at highspeed will wear out the differentials even more so than FF/FR.

Most shops don't offer that because of potential liability of damaging the car.

I remember f1 doesn't has on wheel balancing also

with LSD it will put too much stress to the Balancing machine, as it will have to spin twice as hard since it's spinning both wheels, 1 on the ground means more friction even worse.

good rim ,good tyre &good balancing machine
