AC LINE RUBBING AGAINST FENDER. IT FINALLY BROKE DOWN THE LINE CAUSING IT TO LEAK WITH EXTREME PRESSURE. REPLACE LINE AND MADE A BRACKET TO HOLD LINE AWAY FROM FENDER. *JB

FUEL VAPOR LINE BECAME DETACHED CAUSING FUEL LEAK IN CLOSE PROXIMITY TO EXHAUST PIPE WHICH CREATED A POTENTIAL FIRE HAZARD. I REPAIRED THIS DEFECT BY USING A CLAMP TO SECURE THE LINE BACK TO FUEL TANK. THERE ARE TWO OF THESE VAPOR LINES THAT ARE ON EACH END OF THE TANK AND THEY ARE NOT SECURED WITH CLAMPS FROM THE FACTORY. WITH THE AGING OF THE RUBBER VAPOR LINE IT CAN BECOME LOSE AND WHEN PRESSURE IN THE FUEL TANK INCREASES IT CAN CAUSE THE ONE OF THE LINES TO POP OFF. THIS RESULTS IN FUEL LEAKING AND CREATES A HAZARDOUS FIRE CONDITION SINCE THE EXHAUST PIPE RUNS NEXT TO THE TANK IN THE REAR OF THE VEHICLE.*AK
CATALYTIC CONVERTER WAS REPLACED IN 01/98 THE EXHAUST SYSTEM BEGAN GETTING NOISY AGAIN IN 99 EVENTUALLY THE MANIFOLD CRACK APPEARED.
ENGINE STARTED TO SOUND LOUDER THAN NORMAL WHEN STARTING UP FROM A COLD START. NOTICED ENGINE WAS COVERED IN OIL. WHEN I TOOK IT TO BE REPAIRED, THE MECHANIC TOLD ME THAT THE MANIFOLD EXHAUST BOLT HAD FAILED AND THAT CAUSED MY PROBLEM. HAD IT REPAIRED FOR $300.00. THEN I FOUND OUT ABOUT THE "TECHNICAL SERVICE BULLETIN" FROM A JEEP WEBSITE ABOUT THIS PROBLEM.
WITHIN IN THE LAST 2 YEARS, THE COOLING SYSTEM HAS A HAD AN OFF-AND-ON ANTIFREEZE LEAK. PARTS REPLACED INCLUDE THE RADIATOR, BOTH THE UPPER AND LOWER RADIATOR HOSES, THE WATER PUMP, THE THERMOSTAT, AND THE FREEZE PLUG. A LEAK STILL EXISTS, CAUSING ME TO BELIEVE THERE IS A DEFECT SOMEWHERE NOT YET DETERMINED.
