Propshaft removal
Hi guys.
Still trying to chase this small noise I have on going with my xc90 2011. 'Noise from 40 to 60mph very faint whine or humm from rear BUT only there if you have light throttle only and sounds like its from rear?' I have been in contact with a diff rebuild incase it's my bearing on it's way out. I wanted to see if the prop shaft could cause this noise? I was thinking to remove the prop shaft to trail this but I want to know car I run the car with no prop shaft? Can I remove the prop shaft (REMEMBER MINE IS R DESIGN WITH BIGGER EXHAUSTS) with out dropping exhaust? |

Hi There, yes a worn joint on the propshaft can cause this noise.
On the non R-Design cars with single exhaust I think you can remove the prop by disconnecting the exhaust front joint only - but after that removing the full exhaust is quite easy (the rear hangers bolt on). That said this method relies on being able to move the exhaust to one side which will be more tricky on the twin exhaust. You can drive the car without the prop but keep in mind that the stability control systems expect to use AWD in a sticky situation and your insurance company might have a dim view of it.... so if you do so I would suggest for a short period for diagnostic purposes only.

Do you know if I had a diff bearing on it's way out would I still get this noise with no prop shaft connected? As my noise is only with light throttle etc |

Diff bearings turn when the wheels turn.
So a bad bearing making noise will still make noise when wheels turn. It may sound a bit different when no prop shaft connected and the rear diff is not under load.

The only way I can describe the noise is a a faint whine hum (have to have radio off to hear) at speeds how ever if I take my foot OFF the gas pedal the noise goes away. If I just breath on the gas pedal (touch as light as I can)noise will come back... I dont want to send diff off if no issue with diff.. Does this sound more like a prop noise? Am I right in saying if it was a diff bearing the noise would be there all the time as wheels are turning? |

When I state the faint hum is there when driving and when I take my foot off the gas the noise goes, when I state it comes back with light throttle I mean so light that you do not feel the car pull or any thing, so minor that it is like a signal input etc?? How is the haldex driven?? |
