1999 Toyota 4RUNNER

REAR AXLE HOUSING DEVELOPS PREMATURE AND DETRIMENTAL METAL SCALING AND RUST, CAUSING DIFFERENTIAL BELL HOUSING TO LEAK GEAR OIL. THIS PROBLEM HAS BEEN REPORTED ON A SIGNIFICANT NUMBER OF 1999 THROUGH 2002 4RUNNERS IN A CONSISTENT MANNER AND PATTERN. TOYOTA MOTORS HAS FAILED TO ACKNOWLEDGE OR RESEARCH THE PROBLEM AND USES THE DEFENSE THAT THESE VEHICLES ARE OUTSIDE OF WARRANTY PERIOD. HOWEVER, A CONSISTENT PATTERN OF QUALITY IN THIS PARTICULAR PROBLEM SHOULD WARRANT AN INVESTIGATION BY NHTSA AS TOYOTA HAS BEEN SHOWN TO HIDE AND DISTORT CLAIMS BY THEIR LOYAL CUSTOMER IN ORDER TO COVER UP THESE TYPES OF PROBLEMS. PLEASE SEE HTTP://WWW.4RUNNERFORUM.COM/FORUM/SHOWTHREAD.PHP?T=1948 FOR ONE OF THE MANY THREADS RELATED TO THIS TOPIC THAT DEMONSTRATES THAT THE PROBLEM IS PERSISTENT AND TOYOTA HAS FAILED TO RECOGNIZE IT. *TT

DURING THE ROUTINE MAINTENANCE AND INSPECTION, THE MECHANICS AT DEALER FOUND A RUST THROUGH HOLE IN THE PASSENGER SIDE FRAME RAIL. THE HOLE MAY AND/OR WILL COMPROMISE THE INTEGRITY OF THE BODY ACCORDING THE MECHANICS. THERE ARE ALSO CONSIDERABLE RUSTING ACROSS THE FRAME OF THE BODY, INCLUDING REAR BUMPER (REPLACED 4 YEARS AGO), FRONT BUMPER, SWAY BAR AND EXHAUST SYSTEM (STAINLESS STEAL EXHAUST PIPE AND MUFFLER ARE REPLACED). ALL THE RUST RELATED REPAIR COST OVER THE YEARS IS ABOUT $5,000. WHAT CONCERNED ME THE MOST IS THAT HOW LONG I CAN SAFELY DRIVE THE CAR WITH RUSTING PROBLEM GETTING WORSE?

MARCH 6, 2011: 99 TOYOTA 4RUNNER: I NOTICED MY 4RUNNER PITCHING ON HIGHWAY EVEN AT LOW SPEEDS FOR SEVERAL WEEKS. AFTER I BROUGHT INTO TOYOTA THEY INFORMED THAT THE VEHICLE WAS EXTREMELY UNSAFE - REAR END DIFFERENTIAL HOUSING HAD BECOME DETACHED FROM FRAME ON REAR PASSENGER SIDE - RIGHT REAR AXLE CLOSE TO COMPLETE FAILURE - TOYOTA STATED IT WAS TOO DANGEROUS TO DRIVE. SEVERE RUST ON THE STRUCTURAL AND SUSPENSION COMPONENTS IS EXCESSIVE. ALSO LARGE HOLES IN DIFFERENTIAL HOUSING CAUSING FLUID LEAKAGE. TOYOTA STATED THEY COULD FIND USED PARTS, INCLUDING SUSPENSION BRACKET & ENTIRE REPLACEMENT OF DIFFERENTIAL HOUSING & SWAY BAR COMPONENTS - WOULD COST UP TO $3000 TO REPAIR AT MY COST. ANOTHER OPTION IS TO FIND A MECHANIC TO WELD & REPAIR SUSPENSION BRACKETS. THE REAR TRANSFER CASE IS SO THIN THAT OIL IS LEAKING THROUGH RUST HOLES. FRAME RAILS & ENTIRE UNDERCARRIAGE ALSO SEVERELY RUSTED & DETERIORATED, INCLUDING ENTIRE DISINTEGRATION OF THE REAR BUMPER WITH THE FRONT BUMPER HAVING MASSIVE RUST HOLES. *TR

FRAME ON 1999 TOYOTA 4RUNNER HAS RUSTED THROUGH IN FRONT OF REAR AXLE ATTACHMENT ON DRIVER'S AND PASSENGER'S SIDES. REAR DIFFERENTIAL COVER HAS ALSO RUSTED TO POINT WHERE DIFFERENTIAL FLUID IS LEAKING OUT. THE VEHICLE IS WELL MAINTAINED AND WASHED REGULARLY WITH NO RUST ANYWHERE BUT FRAME AND REAR DIFFERENTIAL. THE VEHICLE IS UNSAFE TO DRIVE AND MUST BE REPAIRED ACCORDING TO MECHANIC. TOYOTA STATES THAT THEY HAVE A VOLUNTARY BUY-BACK PROGRAM ON TACOMA'S OF SAME VINTAGE, BUT NOT FOR THE 4RUNNER? *LN

I PURCHASED A 1999 TOYOTA 4RUNNER 2 YEARS AGO AFTER DRIVING IT OFF THE LOT WE NOTICED WITHIN A WEEK THAT THE FUEL GAUGE WAS NOT WORKING. THEY EXPLAINED THAT HAD THEY KNEW IT WAS BROKEN, HOW WOULDN'T YOU, THEY WOULD NOT HAVE BEEN ABLE TO SELL IT FOR THAT PRICE. I PAID FOR THE FIX AND WAS REASSURED THAT THIS WOULD SOLVE THE PROBLEM. WELL, STARTING ABOUT 1 MONTH AGO I AM NOW HAVING THE SAME PROBLEM. I CONTACTED TOYOTA GOODWILL AND THEY TOLD ME IT WAS ONLY COVERED UNDER INITIAL WARRANTY. I HAVE READ SEVERAL FORUMS AND COLUMNS ON THIS ISSUE AND THE PROBLEM DOES NOT OCCUR WITHIN THE FIRST 36 K MILES SO ALOT OF GOOD THAT DOES. I AM STILL WAITING TO SEE IF MANAGEMENT REVIEWS MY CASE, BUT I DOUBT ANYTHING WILL GET DONE UNLESS I CONTINUE TO CALL BACK. I WOULD THINK THAT TOYOTA WOULD WANT TO EXTEND SOME GOODWILL CONSIDERING THIS IS NOT THE FIRST TIME IT HAS HAPPENED TO ME. THE SAFETY ISSUE IS RELEVANT CONSIDERING THERE IS NO REAL WAY TO EXACTLY TRACK YOUR MILES AND BECOMING STRANDED ON THE SIDE OF THE HIGHWAY OR LATE AT NIGHT IS CERTAINLY NOT A GOOD THING TO HAVE TO EXPERIENCE. *TR

TL*THE CONTACT OWNS A 1999 TOYOTA 4RUNNER. WHILE DRIVING APPROXIMATELY 65-70 MPH, THE SUN ROOF SUDDENLY EXPLODED WITH NO PRIOR WARNING. THE CONTACT CALLED THE DEALER WHO REFERRED HER TO THE MANUFACTURER. WHEN THE CONTACT CALLED THE MANUFACTURER, SHE WAS INFORMED THAT THERE WERE NO RELATED RECALLS. THE VEHICLE HAD NOT BEEN REPAIRED. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 169,000.

I HAVE A 1999 TOYOTA 4-RUNNER AND THE FUEL GAUGE HAS STOPPED WORKING. IT BEGAN BY SHOWING A QUANTITY OF FUEL WHEN IT REALLY DID NOT HAVE ANY FUEL. THIS CAUSED ME TO RUN OUT OF FUEL AND ALMOST HAVE A MAJOR ACCIDENT. IT NOW MAY READ FULL, ZERO, 1/2 ETC. YOU CANNOT DEPEND ON THE ACCURACY. I CONTACTED DEALER WHO TOLD ME THEY KNEW IT WAS A TOYOTA DEFECT BUT THAT THE VEHICLE WAS OUT OF WARRANTY AND THEY WOULD DO NOTHING ABOUT IT BUT TELL ME TO BRING IT IN AND THEY WOULD FIX IT FOR BETWEEN $500 - $1000!!! TOYOTA HAS EVEN ISSUED A SERVICE BULLETIN TSB # EL 010-00 TO ADDRESS THE PROBLEM BUT NOT OFFER REPAIRING THE PROBLEM. THIS IS A DANGEROUS SITUATION FOR THOSE UNAWARE AND COULD RESULT IN DEATH OR SERIOUS INJURY. *TR
