BEGINNING ON 06/09/03 AND CONTINUING TO THE CURRENT DATE, MY VEHICLE HAS HAD A RECURRING FRONT DIFFERENTIAL LEAK. FIRST 3 REPAIRS WERE FOR THE DIFFERENTIAL SEALS, UNTIL IT WAS DISCOVERED THAT THE VENT TUBE WAS PLUGGED, THE NEXT 4 TIMES FOR REPAIR WERE DUE TO THE FACT THAT WHEN THIS VEHICLE IS DRIVEN ON A TRIP FOR AN EXTENDED PERIOD OF TIME ON THE HIGHWAY, THE FRONT DIFFERENTIAL PURGES THE FLUID OUT THE VENT TUBE. THE LAST TRIP I TOOK THE VEHICLE ON WAS A 400 MILE ROUND TRIP AND THE VEHICLE UNDERBODY WAS HALF COVERED IN DIFF OIL, AND IT CONTINUED TO DRIP FOR 2 DAYS. MY CONCERN IS A LONGER TRIP, WHICH I PURCHASED THE VEHICLE FOR, WOULD RESULT IN THE SEIZING OF THE FRONT DIFFERENTIAL AT HIGHWAY SPEED, POSSIBLY CAUSING AN ACCIDENT.*JB

MECHANIC FOUND BOTH FINE AND SMALL PIECES OF METAL IN THE FRONT 4X4 TRANSMISSION CASE, BUT SAID THIS WAS NOT A BIG PROBLEM. MECHANIC SUGGESTED THAT I SHOULD HAVE THE U-JOINTS REPLACED SOMETIME ON THE DRIVE SHAFTS AND THIS WOULD STOP THE NOISE AND VIBRATION. AT COLDWATER, MI.
