93 toyota x-cab,,22re 5 speed,,,i went out 4 wheeling this past weekend and after a while,,the front end started to make a grinding noise and squeeking noise every once in a while,,,every time it was under a load (going up a hill or on the gas) the noise went away,,,the 4 wheel drive still worked great,,,,it even made the noises when i was rolling in neutral ,,,at the end of the day when i got back to the street and unlocked the hubs it was perfect with no noises at all,,also now i noticed that when driveing down the road my steering wheel shakes back and forth a little bit,,,,,,,,,,,thanks for any help
