2000 Toyota 4RUNNER

REAR AXLE SEALS LEAKING GEAR OIL FROM REAR DIFFERENTIAL INTO REAR BRAKE DRUM HOUSING COVERING BRAKE SHOES, DRUMS, AND BRAKING COMPONENTS IN GEAR OIL. LOSS OF GEAR OIL IN REAR DIFFERENTIAL CAN CAUSE DIFFERENTIAL FAILURE AS WELL AS FAILURE IN REAR BRAKING. A NOTORIOUS ISSUE WITH 3RD GENERATION TOYOTA 4RUNNERS DUE TO POOR ENGINEERING OF REAR AXLE SEALS AND RETAINERS, THEREFORE FAILING TO PROPERLY SEAL COMPONENTS. SEALS BEGIN TO LEAK AGAIN SOON AFTER; EVEN WHEN REPAIRED, DUE TO POOR MATING OF SEAL AND RETAINER ON AXLE WITHIN THE AXLE HOUSING. *TT

TL* THE CONTACT OWNS A 2000 TOYOTA 4RUNNER. THE CONTACT STATED THAT THERE WAS OIL LEAKING FROM THE REAR OF THE VEHICLE. UPON FURTHER INVESTIGATION, THE CONTACT DISCOVERED THAT THE REAR DIFFERENTIAL WAS LEAKING. THE CONTACT DID NOT TAKE THE VEHICLE TO A DEALER OR A LOCAL MECHANIC FOR A DIAGNOSTIC TEST OR REPAIRS. THE FAILURE MILEAGE WAS 170,000.

TL* THE CONTACT OWNED A 2000 TOYOTA 4RUNNER. THE CONTACT STATED THAT THE VEHICLE COULD NOT BE STARTED. THE VEHICLE WAS TOWED TO THE DEALER WHERE THE FAILURE COULD NOT BE REPLICATED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED. THE FAILURE MILEAGE WAS 142,130 AND THE CURRENT MILEAGE 144,133. UPDATED 11/27/12 *CN THE CONSUMER STATED THE MANUFACTURER WAS CONATACTED A CLAIM WAS FILED, BUT NO ASSISTANCE WAS OFFERED. THE VEHICLED WAS SOLD AS SALVAGE. THE CONSUMER NO LONGER OWNS THE VEHICLE. SEVERAL TIMES THE VEHICLE WOULD NOT START LAEVING THE CONSUMER STRANDED. IT WOULD STALL IN TRAFFIC. A NEW CLUTCH AND SAFETY CLUTCH WERE INSTALLED, NEW STARTER ALSO. THE VEHICLE STILL WOULD STALL. THE VEHICLE DID NOT COME WITH AN ALARM BUT THE LOCKS WOULD FAIL AS WELL, LOCKING THE CONSUMER EITHER IN OR OUT OF THE CAR. UPDATED 12/10/2012 *JS

REAR DIFFERENTIAL HOUSING COMPLETELY RUSTED THROUGH SUCH THAT DIFFERENTIAL FLUID IS LEACHING DIRECTLY THROUGH THE METAL AND DRIPPING ONTO THE ROADWAY. THIS COULD RESULT IN THE DIFFERENTIAL SEIZING UP AND CAUSING LOSS OF CONTROL OF THE VEHICLE, OR OTHER VEHICLES TO LOSE TRACTION ON ROAD DUE TO GEAR OIL LEAKING ONTO ROADWAY. TOYOTA DOES NOT SELL DIFFERENTIAL HOUSING AND INSISTS ENTIRE DIFFERENTIAL MUST BE REPLACED AT A COST OF OVER THREE THOUSAND DOLLARS. RUST PROBLEM FIRST OBSERVED IN 2005 AND STEADILY BECOMING WORSE EACH MONTH. NO REPAIRS YET MADE BECAUSE OF EXCESSIVE COST. OWNER IS EXPECTING AND WAITING FOR A SAFETY RECALL FOR THIS ISSUE. *TR

REAR DIFFERENTIAL COVER IS RUSTED AND FLUID LEACHES RIGHT THROUGH THE METAL SPRAYING FLUID ON TO SPARE WHEEL AND REAR BUMPER AND ANYTHING IN TOW. COVER IS EVIDENTIALLY CHEAP METAL AND IS POORLY DESIGNED AS THE COVER IS WELDED ON AND CANNOT BE REPLACED WITHOUT REPLACING THE ENTIRE REAR AXLE. THERE IS NO OTHER SIGNIFICANT RUST ON THIS VEHICLE AND THE REMAINDER OF THE AXLE IS IN VERY GOOD CONDITION THEREFORE I BELIEVE THAT THIS IS A MANUFACTURER DEFECT WHICH SHOULD BE ADDRESSED BY TOYOTA. I HAVE BEEN QUOTED $1500-$2000 FOR A REPLACEMENT AXLE WHICH IS 1/4 OF THE VEHICLE'S VALUE. TOYOTA CHOSE A POOR DESIGN AND MATERIAL FOR THIS PART AND SHOULD BE HELD ACCOUNTABLE FOR THIS ISSUE AS IT IS THE ONLY WEAK LINK ON THE ENTIRE VEHICLE, UNFORTUNATELY THE REAR AXLE IS NOT AN OPTIONAL PART FOR ITS OPERATION. I HAVE REVIEWED SEVERAL MESSAGE BOARDS AND HAVE FOUND THAT THERE ARE SEVERAL OTHER 4RUNNER OWNERS IN THE RANGE FROM '99 TO '02 WITH THE SAME EXACT ISSUE AND ALL REPORT NO OTHER RUST ON THE VEHICLE EXCEPT FOR THIS ONE LOCATION. MY MECHANIC ADVISES THE ONLY REPAIR FOR THIS ISSUE IS THE COMPLETE REPLACEMENT OF THE REAR AXLE WHEN ONLY A SMALL PLATE HAS FAILED. *TR
