I have a 91 Pathfinder SE automatic and 4x4. It runs great and I really like but I encountered a problem yesterday. I pulled off the road to talk on the phone a while. It was flat and I left the motor running. When I put it in drive to pull away the right front tire shuttered a little bit and I got a sound coming from underneath that sounds like a tight belt. I looked around and cannot find anything out of place but today while driving around it drove good until I came to a stop. Right before I come to a complete stop it sounded like there were gears clunking around either in the right from wheel or possibly the front axle. Can anyone shed some light on this?
