1998 V70 AWD inspection

I have been looking at a 1998 v70 with AWD. My concern as you might imagine is with the AWD especially the bevel gear. I have contacted a few D.C. area dealerships and indy shops that say that they can do nothing in a pre purchase inspection to evaluate the condition of the AWD. Can the AWD system be inspected to see if it is in good shape? What would I need to ask them to do or do my self with out a lift? Also in doing VS and BB site searches I have found posts that say you can disconnect the system if it go bad and have a FWD car. Every shop I have asked has said no that it is not at all possible. Is this also true? I would love to get some rock solid confirmation on these issues prior to having a pre purchase ingestion done on this car. Volvo techs please help me out here.

Thank You

Aaron

    There is a pdf tech service bulletin available via Volvo Tech Pubs page. The service bulletin describes the freewheel and viscous coupling function test. I purchased the bulletin for about $10 CDN a couple of years ago.

    I can tell you as an owner of a 1998 V70 (not a tech)it is a great car but be careful of issues with vibration in the drivetrain. I bought my 98 new and it had a vibration the dealer could not fix after replacing the drive shafts and finally the transmission. It is very strange because when I had new tires on the car it got better but didn't go away. (The V rated Michelin tires seemed to be much better than the H rated Michelins I ran and they are lasting far longer than the old h rated set.) I also had the vibration show up at a different speed than it does now after the transmission was replaced (it now comes on at 60-65 mph) so go figure. My guess is the AWD systems are extremely sensitive to things like tires that are perfectly matched and if the factory didn't make the unibody or subframe to precise specifiactions the car will exhibit this type of vibration. You can find other posts on teh web about the vibration issue. You will also give up 2-4 miles per gallon in fuel economy with the AWD.
