2001 Toyota 4RUNNER

DRIVING DOWN THE HIGHWAY IN 2001 TOYOTA 4-RUNNER GOING ABOUT 60 AND ALL OF A SUDDEN THE REAR END/TIRES LOCKED UP AND GOT IT TO THE SIDE OF HIGHWAY BARELY AND THEN IT STARTED SMOKING REALLY BAD. VERY LUCKY THAT IT DIDN'T CAUSE A WRECK OR NO ONE GOT HURT. CAN'T DRIVE IT OR NOTHING, MAKES A LOUD KNOCKING NOISE IN THE REAR END AND ALSO WHEN YOU TURN THE KEY ON INSIDE THE VEHICLE ALL LIGHTS ARE ON AND ITS MAKING A TERRIBLE BUZZING NOISE. SO HAD TO HAVE IT TOWED AND THAT COST ME ALSO AND I NEED THE WHOLE REAR DIFFERENTIAL AND THAT'S A LOT OF MONEY. I'VE SEEN OTHER PROBLEMS/COMPLAINTS ABOUT THE SAME THING THAT HAPPENED TO MINE. I REALLY THINK SOMETHING SHOULD BE DONE ABOUT IT, TOYOTA SHOULD BE FIXING THE PROBLEM AND WE SHOULDN'T HAVE TO PAY FOR IT. HOPEFULLY SOMETHING GETS DONE ABOUT THIS. *TR

THE BACK OF THE REAR DIFFERENTIAL HOUSING STARTED LEAKING ABOUT ONE DROP PER SECOND. THE VEHICLE HAS 113,800 MILES. WE BOUGHT THE CAR WITH ABOUT 20,000 MILES. IT HAS RECEIVED THE RECOMMENDED MAINTENANCE. THE SOURCE OF THE LEAK IS SEVERE CORROSION THAT HAS REMOVED MUCH OF THE STRUCTURAL METAL OF THE DIFFERENTIAL HOUSING. THE LEAK IS COMING THROUGH SEVERAL CRACKS THAT HAVE PASSED THROUGH THE REMAINING METAL. THE ONLY AVAILABLE REPAIR IS TO REPLACE THE ENTIRE REAR AXLE HOUSING TO THE TUNE OF BETWEEN $2000 AND $3000. THIS TYPE OF CORROSION IS UNUSUAL. I HAVE NOT EXPERIENCED THIS SORT OF MALFUNCTION IN NEARLY 50 YEARS OF DRIVING. *TR

AFTER I MY MECHANIC REPLACED THE CATALYTIC CONVERTER FOR $1500.00, THIS PROBLEM BEGAN. THE VEHICLE BEGAN TO BUCK (JERK VIOLENTLY) AS I WAS ACCELERATING TO 45 MPH. IT ALWAYS HAPPENS AT ABOUT 20 MPH AS I TRY TO ACCELERATE TO 30, 35 OR 40 MPH. THE ENGINE REVS UP TO 3 OF 4K BEFORE THE TRANSMISSIONS ENGAGES FORCEFULLY. THIS HAS BEEN GOING ON FOR NOW 3 MONTHS. *TR

TOYOTA 2001 4-RUNNER, THE VEHICLE HAS AN EXCESSIVE AMOUNT OF UNDERBODY,FRAME,DRIVE TRAIN RUST SPECIFICALLY THE REAR DIFFERENTIAL HOUSING UNIT. THE PROBLEM FIRST ENCOUNTERED WAS THE RR. DIFFERENTIAL HOUSING RUSTED THROUGH AND IS LEAKING OIL FROM IT.SO I CALLED TOYOTA EXECUTIVE OFFICE AND SPOKE WITH AN EXECUTIVE ANALYST, I EXPLAINED IN DETAIL WHAT THE PROBLEM WAS , SHE ARRANGED FOR THE VEHICLE TO BE TAKEN TO A TOYOTA DEALER AND INSPECTED BY THEIR MECHANICS AND THE REPORT READS AS FOLLOWS. INSPECTED REAR DIFFERENTIAL , INSPECTED HOUSING -FOUND FLUID LEAKING FROM HOUSING AT YOKE THROUGH REAR COVER ;METAL POROUS AND THIN. RECOMMENDED REPLACEMENT OF HOUSING AND ASSOCIATED HARDWARE REPAIR ESTIMATE $1491.28 PLUS TAX. THEY ALSO NOTED SEVERAL OTHER ISSUES THAT I CANNOT BE SURE IF IT WAS CAUSED BY EXCESSIVE RUST OR NORMAL WEAR. THEN UNDER MISCELLANEOUS A GENERAL INSPECTION, BY TECHNICIAN READS AS FOLLOWS VEHICLE UNDERCARRIAGE HAS HEAVY CORROSION - - FOUND PERFORATION AT FRONT SHACKLE ON RIGHT REAR OF FRAME. SECOND PROBLEM, AT THE END OF THE INSPECTION REPORT UNDER THE COMMENTS SECTION THE TECHNICIAN, HAND WRITTEN SAID FRAME IS BAD,RUST PERFORATION (SLOPPY WRITING ) I BELIEVE IT SAID, RIGHT REAR RAIL . SO AFTER THE EXECUTIVE ANALYST READ THE REPORT SHE CALLED ME AND SAID THERE IS NOTHING TOYOTA CAN DO BECAUSE THE VEHICLE IS OUT OF WARRANTY AND THERE ARE NO RECALLS. I RESEARCHED ON LINE FOR EXCESSIVE RUST AND RR. DIFF. LEAKING, AND FOUND MANY OTHER VEHICLES HAVE A LOT OF THE SAME PROBLEMS DEVELOPING. THANK YOU *TR

TL* THE CONTACT OWNS A 2001 TOYOTA 4RUNNER. THE CONTACT STATED THAT THE VEHICLE DIFFERENTIAL WAS CORRODED AND DEVELOPED A LEAK. THE VEHICLE WAS TAKEN TO THE DEALER WHO DIAGNOSED THAT THE REAR DIFFERENTIAL ASSEMBLY NEEDED TO BE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE WHO DID NOT OFFER ANY ASSISTANCE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 120,000 AND THE CURRENT MILEAGE WAS 180,000.

REAR DIFFERENTIAL COVER RUSTED THROUGH WITH ONLY 22650 MILES ON VEHICLE. DEALER HAD TO REPLACE THE WHOLE REAR AXLE ASSEMBLY AT A COST OF $1800 BECAUSE THE COVER IS WELDED ON AND CANNOT BE REPLACED SEPARATELY. MY CONCERN IS FOR THE FRAME RUSTING OUT AND SUBSEQUENT SAFETY ISSUE AS INDICATED BY THE NUMBER OF OTHER COMPLAINTS LISTED HERE. I UNDERSTAND THE TACOMA'S HAVE SIMILAR PROBLEMS AND SIMILAR FRAMES. THE WARRANTY FOR CORROSION HAS BEEN EXTENDED BY TOYOTA FOR THE TACOMA. WHEN ARE YOU GOING TO DO SOMETHING ABOUT THIS? *TR

THE REAR DIFFERENTIAL ON MY TOYOTA 4RUNNER RUSTED SO BADLY IN 9 YEARS OF OWNERSHIP THAT THE STRUCTURAL STEEL FRAME THAT SUPPORTS THE DIFFERENTIAL GEARS (THE HOUSING) CRACKED AND OIL SPILLED OUT ON THE ROAD. I DISCOVERED THE RUST DURING THE YEARLY STATE INSPECTION AND CONSEQUENTLY HAD THE DIFFERENTIAL INSPECTED BY MY TOYOTA DEALER (BERLIN CITY PORTLAND, ME) A FEW MONTHS BACK AND THEY SAID IT WAS STRUCTURALLY SOUND BUT RUSTY. I AM AN ENGINEER AND CLEARLY IT WAS NOT STRUCTURALLY SOUND OR IT WOULD NOT HAVE FAILED IN SHORT ORDER AS IT DID.... THIS FAILURE COULD HAVE CAUSED THE REAR WHEELS TO LOCK UP RESULTING IN A SEVERE ACCIDENT. THIS RUST PROBLEM IS COMMON ON MOST TOYOTA TRUCK FRAMES AND DRIVE TRAINS OWNED IN THE NORTH EAST. TOYOTA HAS ELECTED TO REPAIR THE TRUCKS AT NO COST BUT NOT THE 4RUNNERS WITH THE SAME FRAME AND DIFFERENTIALS. THIS IS DANGEROUS AS [XXX]... THEY PUT ME AND MY FAMILY AT GRAVE RISK.... INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

REAR DIFFERENTIAL HOUSING RUSTED THROUGH. THE HOUSING COVER IS A THINNER METAL THAN THE DIFFERNTIAL AXLE AND IS NOT REPLACEABLE. OIL LEAKS OUT THROUGH THE RUSTED COVER UNTIL OIL IS DEPLETED AND COULD CAUSE DRIVETRAIN FAILURE WHILE OPERATING THE VEHICLE. DEALER SAID THEY WILL DO NOTHING TO HELP. THIS IS AN ITEM THAT SHOULD NEVER FAIL ON A VEHICLE. MY VEHICLE HAS ABSOLUTELY NO BODY RUST, YET THIS PART FAILS DUE TO RUST! THIS IS UNACCEPTABLE AND TOYOTA SHOULD STEP UP AND TAKE CARE OF THE ISSUE. OBVIOUSLY THERE ARE NUMEROUS COMPLAINTS ON THIS SITE AND MANY MORE ON THE INTERNET FORUMS. TOYOTA LOSES MUCH RESPECT IF THEY DO NOT ADDRESS THIS ISSUE. *TT
