I just did my wheel balancing and alignment not long ago, and also change two front tyre.
When the car going below or 100km/h is ok, but once it over 101km/h, the car suddenly feel very shake. May i know what cause the problem like that?

bring the car for tuning, not just balancing

engine shaking or all car shaking...

try to send to mech and checking ur car lower arm...maybe already worn... just my opinion.. ehehe

did u do any on-wheel balacing after swapping the tyres??...

I think he did the wheel balancing...

Btw, i've experience the same problem u have with my 405 Peugeot, after certain speed, then the car will shake like washing machine... and after some checking, the main cause is the drive shaft koyak. u might want to check ur drive shaft?

U mean engine tuning? its not the engine problem i guess

The front part all shaking, like washing machine lo, haha. Shake till i also pening, and dare not go further.


My driveshaft on lefthand side already got sound, but i think just a minor one cause i change not long ago. And the sound only come out when do max turn.

mine problem is right after 101km/h it suddenly become shaky one woh, not happen gradually from 90km>100km. Something wrong with the alignment?

Then I try to drive until 110km/h and quickly press clutch to make it disengage become freegear. But the shaky doesnt dissapear. I presume the problem is not Engine or Transmission Gearbox related.

alignment and balancing...normally for my waja auto..

Rim Bengkok..?will also happen..

Lower Arm Bush...?check it..

or wat Rim u using?if stock come wif rim13" and u upgrade to 15" and above..then try add wat the called is CORN.it put all around ur rim there..
is jus a round thing..

u tell them CORN at tyre shop,they will know it..
^^

for me the problem like my frenz kancil... lower arm and liazup rod prob... ehehe

just sharing my experience...

Yes, Alignment and balancing.

alignment n balancing already check when change type
btw, i still using the same width/size tyre,

Normal shop do normal balancing for normal driver only. U go back the shop ask them do over-wheel for u. Tell them u sometime need drive over 110km/j. This is my exp la, last time I also face this problem. Finally fixed with over-wheel.

It's your driveshaft. If your driveshaft is faulty, even if you do alignment, balancing, chamber it won't work. It will still lari afterthat. The moment you hear krrukk krruukk sound coming from the driveshaft, whether soft or loud, it is faulty already.

The day when I change new tires, my both driveshaft already koyak. The tireman asked me to do chamber settings, since both front tires went inner. Then upon testing the car, he found out that both of my driveshafts already koyak. So he told me to change the driveshafts first, then come back some other day to do the chamber settings.

I then immediately I go to my mech shop, and change both sides, then head back to the shop. He redo the alignment and chamber for me.

try to continue raise ur speed..if only shaking within a range, eg: between 100-120km/h....go check ur driveshaft....

remember get a experienced mechanic.
previously i been going for 3 mechanic, all say my driveshaft no problem. and the 4th which is my dad fren, just test drive for 5min, then confirm its driveshaft problem. after change, no shaking anymore~

will taking out tyre effect over wheel balancing?...coz that day i change brake pads, then vibrate again around 110km...then redo over wheel balancing, yesterday night, driving along federal, felt the steering shaking and vibrating...but then after sometimes no shaking/vibrating..but very minimal..la... ....wads the problem?...if i din hold the steering, it will vibrate slightly..even over balancin has done..

nope... wont affect ur wheel balancing if jz remove ur wheel.... thats why we have off-wheel balancing machine... they pre-balance the wheel before fitting it to ur car...

Since my problem almost the same, dun think i ned to open new thread. Last weekend, went back to my hometown in Perak. To & fro with average speed around 120km/h - 135 km/h, no problem happened. This week, i went outstation from Monday - Wednesday, came back on Thursday. Went by plane, so i parked my car at my office parking lot coz got roof & security guard. So, the problem is since thursday till now, my car shaking very badly when i drive over 100km/h, as if the engine wanna fall off. Does it happen because drive shaft oso? I already change my front drive shaft late last year, not even one year. Need advice here coz dun wanna go to workshop with zero knowledge of the possible cause of the problem. Nowadays, too many dishonest w/shop, later they will charge me for something that i dun even have to change. Thanks in advance.

BTW, some info about my car - Proton Wira Aeroback 1.5 (manual), 2002 made.

it shakes even when u let go ur accelerator pedal??... or jz shake whenever u accelerate???...

if shake when u accelerate, could be driveshaft...

if shake whenever it moves even free gear slowing down, check ur wheel balancing first...

It shakes when the speed over 100 km/h.. I mean, when i accelerate over 100 km/h the car starts shaking even when i let go the accelerator pedal as long as the speed still over 100 km/h.

Hmm.. seems like i have to change my driveshaft yet again.

Its either your wheel not properly balanced or you inflate ur tyre at the incorrect air pressure.

Please make sure your tyre not kembung.This happens if water vapour gets inside your tyre.When it cools,it condenses on ur tyre wall.

if it still shakes when u let go ur accelerator even at speeds of 100kmh, might not be ur driveshaft... check ur wheel balancing and other bushing around ur suspension geometry...
