Sound coming from back tyre

[thaiedwin]

I have a issue with my W220 when I hit 80km/h and above there is a zha zha sound coming from my back Tyre what could be the issue?

[Tanzy]

How old is the tyre?

[thaiedwin]

I changed like 2mths ago only ran for about <10,000km

[thaiedwin]

could it due to disk brake?

[jtang]

Could be due to many factors. Check the whole tyre...there could be a stone or solid debris stuck in the tread grooves.  Check the tyre for any bulge on the contact surface by running your hand over it. Unlikely to be brake rotors, as the noise is usually high pitch metallic noise.

Checked and nothing on tyre wheel....all is normal

tire to old and too hard. I hv same problem previously. now i make sure i chek the Manufacture date before i buy. The DATE are on the tire mark as example "11/12" mean week 11 of year 2012.

Never buy tire more than 12 months old.

tyres have shelf life of 5-7years.....how could it be 12mths expire? my tyre is made in 11/11

The older the tyre, the more hardening of tyre rubber compound. That's why older tyres from the shelf are usually cheaper. I would avoid tyres more than 1 yr old too..the 5 yr old & above ones run the high risk of tyre bursting.

The last time I had similar issues was when there was a nail stuck in the thread. Sound came from the nail brushing against the road surface.

Edwin....later you send your car to me lar....I check for you.....

is ur car on staggered wheels? try seeing if the rear wheels are protrude , i used to have too fat rear wheels and when i run on highway the tyre sometimes will rub the fender and the sound is exactly the same.

Wow see and see say crank shaft dust cover broken and if change very labour so they just break the dust cover and done

If no dust cover, the drive shaft will surely wear out faster as the all the dust & dirt get in . By removing it, it's only a temp solution.

[thaiedwin]

See and see say if change the cover is very labour taxing and not only that, they might have aligment issue as the car age already and many parts start to turn old. Most of the rubbet parts is already harden and cracking if not done properly is not the tyre will vibrate is the whole car will vibrate very badly by then it's deem to enter scrape yard

Crank shaft dust cover??

 

Engine crankshaft has dust cover?

 

[thaiedwin]

Not in engine compartment is near exhaust area.....Below the rear seat area....

I had some noise coming from back seat and it was traced to worn shock absorber. Changed 4x SA and noise disappear.

Have this problem before in my previous car. Changing of the wheel tie rod dust cover is quite a big job, especially, the inner one. The car must be taken up on a jack, wheel out, wheel hub out, wheel bearing out then can access the rubber dust cover. After replacing the dust cover, there is a grease to fill into the dust cover to ensure no dust gets in. The wheel bearing assembly is put back and the car wheel alignment need to be done.

 

There again, I feel it is very unprofessional for C&C to offer the short cut method. This is because, very soon dust and dirt will get into the wheel bearings and the bearing and shaft will wear off prematurely. The best thing to do is to bite the bullet and get the proper thing done including changing a full set of rear bearings (left and right). They would have worn out already or almost worn if you have not change them for the pass 7 years. If not, a few months later most probably, u would be visiting C&C to change the bearing and also the wheel shaft. That would be real expensive.

might be cause the SE knows my car is going into CnC and sleep soon....haha since we have the interest to change car

Expensive in labour?
