if not mistaken is the machine itself that spin one wheel, not two wheel. So I scare it will damage the gearbox

A search on the internet on subject matter doesn't gather much. It's pretty much only hearsay without any technical substance as to how actual damage could be done. So, it's more like human's nature, fearing the unknown.

I had done once before on an Exora Bold cfe a few years back, and the car is still fine today. I'm pretty sure that the gear was at "N" position when the on-wheel balancing was done. So, the gear was effectively disengaged from whatever spinning that was being done, no? Even if the gearbox was really being affected, is it so fragile that it can't withstand any stress for a mere 2-3mins of spinning? I can't remember clearly though if only one or two wheels were being lifted off the ground while the balancing was done. If I'm not mistaken, both front wheels were lifted. But even if only one wheel was lifted, how it would cause damage is everyone's guess. We've people mentioning about damaging the slip-differential mechanism, absence of lubrication, etc, etc, but there's just not a single explanation on the technical details. It'd be best if some technical people could clear the air once and for all if the hearsay damage is a fact or fiction.

Till then, it's up to us to decide what's the best for our cars.

My preve is 10 mths old, 2 mths ago, I also heard 'tak' sound when I press the brake hard, and after that same 'tak sound when I press the accelerate pedal. The same 'tak' sound come when I hit road bump, and also turn my steering to left or right until the end while parking... it is really annoying...

at 1st, I sent it to sc and I believe ntg had done, no improvement at all, I complaint and sent for 2nd time and my car was in sc for 3 days, and SAME, NTG SEEMS TO HAD DONE. they told me they will order a part, to be changed in front absorber, exactly 1 week had passed and i'm still waiting the part to arrive......

For my case is coming from behind, if want to claim parts or let them to fix need to do it on weekdays, weekend sc only do normaly service, tmr i going for 30k service, and i face 1 problem recently which is hard to start car. Morning start ok, only face the problem when after stop the car for a while then start again will face this problem

That's right, CVT does not disengage entirely in N, there are pulleys that are permanently spinning the belt. On normal driving situation, the transmission fluid is pumped with the drive of input power. There will be a concern of lubrication when letting the wheel spin freely, even especially if the engine is turned off during the on-wheel balancing.

How about doing the on-wheel balancing with the engine running, but in "Neutral" gear. It will be similar to cruising down a slope with engine running and gear in "Neutral", no?

At least the CVT fluid pump is working a bit. Again, even on normal situation, putting N when cruising down a slope is not a good practice too. Again, it is a concern of lubrication to the gearbox. Hence we do not tow with the driving wheels on the ground.

However, I have heard about the PROTON SC doing the skimming of the brake discs directly on the wheels. So, in this case, for front wheels, it shouldn't be a good practice right?

The speed of rotation is much faster for on wheel balancing.

yes. 1st i also heard the sound was from rear wheels/shock absorber, but was told by foreman it was cause by front wheel. i also noticed tht the sound came when my front wheel hit road bump...

u try to sit at rear seat and try to hear where the sound is actually coming from...

yeah, sometime my car fail to start as well... but it didnt happen frequently so i jz ignore it for now...

As per the manual, need to swap the wheels, front to back and back to front once 20,000 km is reached. Mine is nearly there.

Do we do that at SC?

BB
Free?

Do they also do wheel balancing as part of the wheel rotation? Or no need as long as I have not changed any thing on the wheels? But the tear and wear on the threads will result in some in-balance.

Thanks.

Some SC can do it, some can't.
Not free, even in tyre shop is not free.
Optional.

The tyre swapping is entirely optional, although suggested. Check the tyres condition yourself and you can justify if a rotation is needed by the wear. I used to do it religiously, but I've learned that it is not necessary as long as there is no unusual/excessive wear.

Thanks.

Will measure the threads and see. If they are uneven, then I will swap the tyres.

Took measurements on my tyre's treads.

The front tyres are about 2 mm lower than the back tyres. Measured at 3 locations for each tyres.

With 1.6 mm depth as the minimum (see manual), looks like I better swap the tyres around at the end of 2016 rather than now, and change out the 4 tyres at the end of 2018 (or earlier if the tread depth gets to 1.6 mm earlier).

I know the wear and tear vary from day to day even with the same driver. The above will give me a guide.

Cheerio.

Hi guys,

According post #2



My car is CamPro IAFM+ just one month old. But the passenger side is beeping and blinking when seat belt is not fastened. Is mine CFE then?

Maybe they just extended the safety feature including seat belt warning. But IAFM+ engine is certainly different from CFE.

My Preve EXE more than 1 year old also has the seat belt sound warning for both driver and passenger.

hi guys, i installed a reverse camera and installed it above my back number plate. problem is, the image that appears on my HU is reversed. anyway to reverse that?

go back to the shop that u installed then.. LOL, technician should test out first before install back the dashboard face.

Anyone change their timing belt yet?how much does it cost for timing belt alone?
