I've got a 97' Mountaineer (5.0 V8, AWD, 140,000 miles).
Over the last several months I've noticed a grinding noise at speeds around 10-30 mph. At first it was barely noticable, but now I hear it all the time. I jacked the truck up on all four corners and had a friend hop in the seat and run it up to around 20mph where the noise was very noticabe. I got under the front and I can tell it's coming from the front differential. It sounds like the pinion bearing is going bad.
Is this a common problem? What should I expect to pay for a shop to drop the front diff and repair the bad bearing(s) ?
I guess I could pull the diff out myself, it looks like it's only atached at 4 points. It this something I could do myself?
Thanks
