Hi all,
This is going to be very difficult to explain but I will do my best and would appreciate any feedback greatly as this is really p$$ing me off. Car: AU XR8 Series 3, Auto, IRS Rear end Problem: When driving between 50 and 70kph, a noise in the cab has developed which sounds like a tyre has uneven tread (rythmic sound with each rotation). I have removed each wheel one by one and replaced with a wheel I know is OK, road tested and this did not change the sound at all. I have tried coasting in neutral, applying handbrake, disengaging handbrake, driving with brakes on, all at speed and no effect on noise. Is there anything else in the driveline which could become out of balance and make this sound ie. wheel bearings, diff, driveshaft, cv axles on IRS?? Cheers, Simon |

Yep id go wheel bearing too. I had similar problem not long ago. Does it get any worse while turning, when putting more weight on one side. That might narrow it down a bit?

Dry CV joints ? Their sealed within the boot.. If there is a split boot then they are buggered.
But yes I'd go with Wheel Bearing |

my point, it doesnt say anywhere that the boots arent split and i didnt feel like repeating wheel bearing like everyone else, i was just giving another option that can create same type of noise

Is it coming from the front or rear? jack it up and give the wheel a riggle, See if its your bearings... If not get it on a hoist and turn and move the wheel if you get some squeaks id say it'd be your lower/ upper control arm bearings?

Have something similar in passenger front; rhythmic thump which sounds like a tyre out of round. I swapped it with the other wheels and it still happened so put it up on the hoist and checked the bearings, brakes and so on - all fine. Mentioned it to a tyre guy; he took it for a spin and he reckons it is caused by the tread pattern on the Firestone tyres now that they are down to about 70% worn. (All the wheels have the same tyres and they've been rotated so the wear is pretty much the same on all.) Awful tyres, btw.

Thanks heaps for the replies,
I did a fair bit of driving today and tried swerving left to right at speed and it made the noise less apparent when veering to the right. When I swapped out each wheel yesterday I did rotate the front wheels by hand and checked for shimmy but all seemed ok (probably not a very good test as there is no load on the wheel bearing) I guess that I could reasonably suspect the front driver's side bearing or either of the rears, can they be inspected without replacement? Cheers, Simon |

Huh? lol just got out to each wheel with the car on the ground grab each wheel and try to move it- up and down then side to side if you have movement its a bearing, If you dont get any movement jack it up you'll need a trolley jack and move the wheel side to side if you get some squeaks... Its most likely your lower control arm bearing...
I had to replace mine it fixed it 9/10 it'll be your tyres and cabin noise- kinda sound similar to a diff whine, but coming from your passanger firewall.

I'd say its wheel bearing, i had the exact same noise in my car and i just had the bearings replaced and now its all sweet! Warning, dont hesitate to go get them checked asap, mine were turned into dust and i was very close to a siezed wheel.

Just rang ABS (auto brake service) they quoted $285 per side to fit new hub. I think I will do it myself using the brilliant how to from Ron West.

Success!!
 : I replaced the driver's side hub today and the noise has gone. Thanks to all who gave advice, you were spot on. Here are some points of interest I thought I'd share as it may help those who tackle this job in the future. 1. Print out the How To guide by Ron West http://www.fordforums.com.au/vbporta...article&id=319 and read it carefully. 2. None of the Auto shops had a 35mm socket. I ended up borrowing one from a mechanic. 3. I jacked car up and tried rocking wheel from top to bottom but it felt totally sound even though bearing proved bad. Diagnosis was made by road test ie. turning to the right the sound went away. 4. The top caliper bolt was seized and I used an Irwin Bolt Grip to get it out. Good luck! Simon |

Wheel bearings ?? Try jack car up an rotate the offending wheel fast an slow,check your wheel weights are still attached as they help balance the wheel and make sure all your wheel nuts are tight ,,i know it sounds dumb bt if not tight they unscrew themselves.........then if still no good get a wheel balance..i have kinda same issue with a strange whooshing noise like air induction noise or wheel needs a balance coming from p/s/f
