AWD grinding noise
i have recently bought a second hand xc90 2005 2.5 T AWD 63k km's - for my sins it appears! i did hear and was warned about the auto box in volvo's but brushed it aside thinking this is a luxury car and the problems of a few were probably of their doing; well it seems not. my first question is; is it a case of WHEN rather than IF the auto box will fail? secondly can anyone help me to understand what could cause this problem? when i pull away from a stop there is an awful grinding noise which i can feel up through the peddles; friend thought gearbox rubber mounts? & regarding the 4 wheel drive- i recently went into some sand with my front wheels and got stuck (my rear wheels were still on hard ground) when i tried to reverse out the rear wheels did not turn at all and there was this awful noise coming out the the auto box, but i continued but eventually gave up and had to be pulled out by a friend, all the while being laughed at with my new AWD Volvo!

Prop the car up with wheels off the ground and check for spining.
Read or have the DTCs read. If you are into fixing yourself maybe get a China Dice and VIDA off Ebay. Find a good independant. AWD drive at franchise could be expensive fix. |

thanks, i did what you suggested and not good news. the rear wheels do not turn and there is that grinding noise; sounds more like gears grating. i read on someone else page that they had similar problem and they ended up replacing a splined collar? i suppose in the diff to the rear wheels? how will the VIDA dice help me with a mechanical problem? i'm sure i'll end up buying one anyway.

If the rear wheels are not spinning with the car in the air, was your rear shaft turning?
Is the grinding from the front end? Front end is angle gear and splined sleeve. VIDA / DICE will not help with angle gear, but technical instructions in VIDA are quite useful, although sometimes forum repair instructions are far more useful. |

i did not check if the shaft was turning but the noise was definitely coming from the front. your thinking about the angle gear or splined shaft i feel is correct. reading from others; is it possible the clutch pack which tells the unit to send power to the rear wheels could be faulty, and would the VIDA be able to pick that up? looking into every possibility before the worst case - major repair! thank you.

can anyone tell me if i remove the prop shaft will that affect the drive? i"m aware it will make it only front wheel drive but will it cause any major damage? my thinking is with no load on the rear drive shaft it will not give me that grinding noise, this is temporary until i can get the car to a volvo dealer.

I am 99% sure it won't be just the sleeve
One or both sides of the sleeve will have stripped it's splines on the transfer box or gearbox In turn this usually also damages the splines on the transfer box or gearbox, too It won't cause anymore damage running it without the prop, even if it is making more of a noise |

My worst fears have come to pass since buying this car, what next; new gearbox? Where can I get a detaled schematic of auto box, angle plate etc. It will help me understand how everything works ? Many thanks
