Whining Noise (Not My Wife)

[Vivasanti]

I have a 2005 BA falcon 130,000 kms approx, every now and then theres a whining/whiring noise, at first I thought it was the tires on some particular tarmac, but could it be the diff? how loud is a diff whine? and how can you tell if its the diff?

It doesnt do it all the time and I was in getting a wheel balance today, and the guy there told me that one of my rear tires is misshapen (im in he market for 2 new rear tires) so this made me think it could be the tire on certain grades of tarmac?

any info would be sweet?

cheers team.

A diff will normally be a high pitch constant whine like the sound of straight cut gears (in my experience anyway) and a whur when backing off. I doubt it would be the tyres.

Is it an expensive job getting it fixed, would probably try new oil first yea?

Thanks, im pretty sure its just noisy tires, its only doing on certain tarmac, doesnt do it on the smooth stuff noise doesnt change with accelerator off/on, it dissapears when going to smooth tarseal.

My BF used to do it only on certain roads, bloody loud sometimes aswell. With 20s even worse.

Thanks for your reply, yea ive got 18s on so even worse!

It sounds like tyres/bitumen type. Will still do it with new tyres.

Welcome to inconsistant road surfaces :f*ckyou:

[Never had any say Panda]

Yeah definitely road surface.. Are you driving across much open grade asphalt or concrete pavement (freeways)? They tend to make a horrible whining noise..

[Vivasanti]

Not sure what surface consists of here in New Zealand but yea, its the first time ive owned a car with 18s on it also, so that prob makes a difference also.

Whineeeeeeeeee, ugh, just wanted a nice quiet car to carry my family in :D
