Noise from rear axle
After a puncture i fitted the space saver spare wheel and within a few miles the rear transmission had seriously overheated, after being recovered i had the diff nose seal and dust shield changed along with fresh oil. There is now a slight noise from the rear axle, barely audible when accelerating but louder as you back off the throttle. The noise is present even when knocked out of gear, coasting. Anyone else experienced similar? I am worried that if a bearing breaks down it may take out the rest of the transmission.

Browsed and found this. Amazed as I thought AWD wheels and tyres had to be closely matched to avoid transmission damage, therefore would be astounded that any space saver tyre might not be closely matched ? Don't know too much about this but assume (Haldex ?) 4WD transmission has been damaged as a result ? Sorry to hear of this issue, good luck with a cost effective solution.

Thanks for the update, so many people on the forum are keen to put forward there problems but are less keen to offer up any subsequent solutions thereby potentially benefitting other members.
I guess your experience underlines the importance of similar diameter wheels and or tyres when running a 4WD vehicle ? Genuinely pleased that on the face of it you have escaped a potentially expensive (being a Volvo!) issue, well done ! Breath a great sigh of relief and enjoy your Volvo while you can (until the next curveball!). |
Curious.
There is a post elsewhere about space saver wheels. I commented about the handling on our XC70 when a space saver was fitted to a front wheel. Someone else suggested that it was best/advisable to remove a good rear wheel and fit it at the front and fit the space saver on the rear. Not a good idea if AWD I fear.

With new tyres fitted to the front now, and a fifth Comet on its way for a spare, i hope all will be good from now on. |
What is a “Comet”?

Will any of you peps please tell me what year the cars are you are talking about? What you are describing I believe is the case with the early Volvo V70/XC 70/V70 Cross Country, ( to approx. 2002/3MY) as I believe they have a different type of AWD system. This system 100% is VERY VERY sensitive to differences in tyre diameters - to the point where different tread depth is even critical. The later V70/XC 70 use Haldex series 2/3/4 etc which I believe has no issue at all with different tyre diameters. I have a 2004 V70 AWD R and have had no issues with overheating, but do fully agree with comments about squirrelly handling on a spacesaver. Cheers Bob |
