help! my car vibrate..

[trxxpoyo]

hallo all sifus,
i'm driving ae111 corolla, and the problem is my car starts to vibrate when accelerating from 90kmh to 100kmh. but if i let go the pedal or free the gear, the car stops vibrating. anybody experienced this kind of problem?

Please check your Drive Shaft. Hope it helps.

Cheers.

from what i went thru, u first need to check ur rims and tire... if all ok, than check ur absober and absober mountings, if ok also than u have to check ur drive shaft... but normally drive shaft if no noise means it's ok...

Couldn't agree more...

 

[ek_elleh]

pls check your exhaust piping..
maybe touching chassis/body during acceleration..

 

[trxxpoyo]

hmmm..i dun think the problem coz by the exhaust piping touching the body..
have to check drive shaft / absober mounting... how bout engine mounting?

 

[blutuik]

check ur rims & tires....
i hv d same problem last year...
vibration disappear after i change rim & tires..

 

[Jordy]

first thing...check ur rims to see if it is bengkok or not... and also try to do balancing on ur tyres
2nd... try to ask ur mechanic to check your bush for ur lower n upper arm...
I have to same problem like urs last time...and it's actually due to my lower n upper arm bush all mati liaw and also my rims are bengkok...that's why no matter how many times u balance ur tyres also wasting money niah.... hope it helps... just my 2 cents

 

[zmays]

normally people said if car vibrating during 90km/h to 120km/h is because unbalanced tyre. and i have drive toyota, proton, perodua, datsun that; if front tyre not properly balanced/not balanced, car tend to vibrate at that speed..can any sifu provide any technical explanation...?

bcoz seems the theory is correct...for me

 

[mamatAE111]

if only vibrate when accelerate(tekan minyak), then most likely driveshaft.
If cruising at 90-100km/h, already let go of accelator(lepas minyak) and car still vibrate, then could be rims, tyre damage..

 

[ahaw]

those who experienced with drive shaft prob, can u briefly explain the diff between inner d/shaft failureeeee to d outer one? apart from 'klak2' sound, does it show any other symptoms?

--- easy said those mechanis with fields exp...

yup, i've been to Kedai Tayar asking bout this problem. they said it is not caused by unbalanced tyre or rims bengkok because the car will still vibrates if i let go the pedal.

yeah, can anybody explain bout Ahaw questions?

if outer d/shaft kong, it will have ktak!ktak! sounds when full cornering(partially cornering also do if too bad).. did u check ur outer d/shaft boot? koyak or not? if koyak the possibility bcos of d/shaft is high..but my heart says engine mounting..
jus my 1cent..

 

[mamatAE111]

go to a mechanic and lift the car. grab the outer driveshaft boot and shake. there was some freeplay in my outer driveshaft boot assembly and the hub. Change driveshaft, problem solved.

When my engine mounting worn out, even during stop at traffic light my steering wheel shaking. Different symptoms with driveshaft.

-absorber
-tire
-balancing
-alignment

True... with budget constraints, start with the cheapest and easiest thing 1st. I would suggest balancing n rotate the wheels.. I'm not 100% sure but i think your drive shafts do not have the same length which will cause one tyre wear faster than the other one.. since i changed to new tyres this year, i've been rotating + balancing every 5000km together with service.. additional RM8-10 only.. so far so good..

other things like drive shaft, rod end, ball joint and bearings u can check by moving the tyres while ur car is on a jack..see got freeplay/clearance or not..

hope this helps..
