since they both work off the speedometer cable/electrical and the odometer still works this sounds like the speedometer head is bad and needs either repair or replacement.

If you have someone check the engine computer for trouble codes, you'll probably find a code for the speed sensor in the transmission.

the odometer usually runs off the cable that operates the speedometer, if the speedometer is working there is a problem with the odometer, you may have to replace the speedometer to fix the problem.......hope this helps......cheers

There are actually two gears that you need to replace, a large one and then smaller one that rides inside it. You can purchase them both at www.fcpgroton.com These can also sometimes affect the operation of your speedometer. Do you by chance have an ABS and TRACS light on? If so the speedometer issue may be related to your ABS controller.

you need a new odometer there are some worn teeth that when it gets to this spot it stops i am a volvo tech see it often on the 240 and 740 series cars

Possibly a little gear inside the odometer has broken down. You find theese gears easily on E-Bay. http://shop.ebay.com/?_from=R40&_trksid=m38.l1313&_nkw=volvo+850+odometer&_sacat=See-All-Categories

Odometer is turned by a mechanical gear wheel, which is the likely culprit.

check the wires plugged to the rear axle center /pull on them/if its the odometer the replace the gear in the speedo head IPD site
