XC70 whining rear diff.
 

I have a 2010 XC70 AWD, the bearings in the rear diff were so noisy that I have had to have it replaced today, the car had only covered 74,000 miles, and I was shocked and dissapointed that the diff should fail so soon, has anyone suffered the same problem with such a low mileage car?
The car has a full Volvo service history and after many letters and emails Volvos final offer is 20% contribution towards parts and labour, very poor!
This is my first and by the looks of it my last Volvo!

I ave a 2011 with 143k on the clock and that's fine...

I thought I had the same problem, 2005 V70 awd, 74000 miles, but it was the prop shaft bearing!

Rear diffs failing on volvo's are very rare,

Ive worked for volvo 15 years and think ive seen 4 in that time

I bet they had FORD cast into the side ... It is possible to change the faulty bearing , one is numbered , the other might be able to be located by measuring it . Or take the unit out and let a transmission specialist repair it .
