AS I KNOW OTHER PEOPLE HAVE POSTED, I HAVE THE CLASSIC 4RUNNER REAR DIFFERENTIAL SEEPAGE. MINE IS A 1996. SEEMS TO BE DUE TO A BAD CASTING FROM FACTORY. NEVER HAVE I RUN INTO THIS BEFORE. VEHICLE WAS REGULARLY WASHED, HARDLY ANY RUST ON ENTIRE VEHICLE, BUT FOR THE REAR DIFFERENTIAL CASTING TO BE RUSTED THROUGH/POROUS ENOUGH TO SEEP GEAR OIL THROUGH THE INTERSTICES WHILE MAINTAINING STRUCTURAL INTEGRITY (SAFETY ISSUE?!!!!!) IS A MAJOR FAILURE FOR TOYOTA AS FAR AS I'M CONCERNED AND SHOULD BE REDEEMED BY COMPANY. I SEE FROM READING ONLINE BLOGPOSTS THAT I AM 1 OF MANY THAT HAVE EXPERIENCED THIS PROBLEM. I'VE HAD MANY OTHER OLDER VEHICLES, ONE IN MY POSSESSION NOW (1989 FORD F-150 WHICH HAS BEEN USED IN WINTER BUT SAT ALL LAST SUMMER, AND HASN'T BEEN WASHED IN YEARS) THAT HAS NO PROBLEMS REMOTELY LIKE THIS RELATED TO THE REAR AXLE. SOMEWHERE ALONG THE LINE TOYOTA PUT OUT FAULTY REAR AXLE HOUSINGS, AND I'D LIKE TO SEE THEM STAND BY THEIR PRODUCT AND FIX THESE---AS I'M SEEING THROUGH INVESTIGATION THAT THIS IS A COMMON PROBLEM WITH MANY TOYOTA OWNERS. SAME PROBLEM. TOYOTA HAS FAILED TO ADDRESS THE ISSUE, AND I'M AFRAID THEY WILL LOSE MANY CUSTOMERS (INCLUDING MYSELF) IF THEY CONTINUE TO IGNORE THE ISSUE. TOO BAD. THE TRUCK STILL RUNS AND LOOKS GREAT OTHERWISE. SEEMS LIKE A LARGE PRICE TO PAY AS FAR AS LOSS OF BUSINESS FOR TOYOTA, BUT TO NOT ADDRESS A SIMPLE MISTAKE LIKE THIS AND MAKE THE CUSTOMER HAPPY?-----THEIR CHOICE. IF YOU CAN ADDRESS THIS ISSUE WITH TOYOTA AND MAKE THEM REPAIR THEIR MISTAKE, I WOULD GREATLY APPRECIATE IT, AS I'M SURE MANY FORMERLY HAPPY TOYOTA CUSTOMERS WOULD AGREE. THANK YOU FOR YOUR TIME, A CONCERNED CONSUMER. *TR

DIFFERENTIAL/AXLE HOUSING RUSTED OUT. I PURCHASED THE TRUCK THIS PAST WEEK AND NOTICED A SIGNIFICANT AMOUNT OF RUST ON THE DIFFERENTIAL HOUSING AND WHERE THE SUSPENSION PARTS CONNECT TO THE HOUSING. THIS IS WHAT HOLDS THE DIFFERENTIAL/AXLE ASSEMBLY TO THE TRUCK. IF LEFT UNCHECKED THE COVER WILL EVENTUALLY RUST OUT AND LEAK OIL AND COULD POTENTIALLY LEAD TO A CRASH IF THE DIFFERENTIAL LOCKS UP DUE TO NO FLUID. ALSO THE BRACKETS COULD RUST OUT CAUSING THE SUSPENSION PARTS TO BREAK AWAY FROM THE HOUSING CAUSING A CRASH. THIS IS A KNOW ISSUE ON 4RUNNERS AND WELL DOCUMENTED ON MANY INTERNET FORUMS. *TR
ON CERTAIN 2-WHEEL-DRIVE (2WD) AND 4-WHEEL-DRIVE (4WD) 4RUNNER SPORT UTILITY VEHICLES, A COMBINATION OF HEAVY LOADING (SIMULTANEOUS LOADING TO REAR GROSS AXLE WEIGHT RATING AND GROSS VEHICLE WEIGHT RATING) AND SEVERE STEERING MANEUVERS COULD CAUSE THE 2WD 4RUNNER TO LOSE DIRECTIONAL STABILITY.
Consequence & remedy
Consequence: THIS MAY RESULT IN A LOSS OF CONTROL AND COULD INCREASE THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE REAR SUSPENSION PARTS. ALTHOUGH THE 4WD 4RUNNERS DO NOT EXHIBIT THE HANDLING CONDITION, TOYOTA WILL RECALL THESE VEHICLES TO AVOID ANY PUBLIC CONFUSION AS TO WHICH VEHICLES SHOULD RECEIVE THE REPLACEMENT PARTS. OWNER NOTIFICATION BEGAN FEBRUARY 28, 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT TOYOTA AT 1-800-331-4331.
THE STICKER REQUIRED BY PART 575, "CONSUMER INFORMATION REGULATIONS" TO ALERT THE DRIVER OF "THE PARTICULAR HANDLING AND MANEUVERING CHARACTERISTICS OF UTILITY VEHICLES" WAS NOT AFFIXED TO THE DRIVER'S SIDE SUN VISOR.
Consequence & remedy
Consequence: CONSEQUENCE OF NON-COMPLIANCE: OWNERS MAY NOT BE AWARE OF THE HANDLING AND MANUEVERING CHARACTERISTICS OF THIS VEHICLE INCREASING THE RISK OF A VEHICLE ACCIDENT.
Remedy: DEALERS WILL REPLACE THE SUN VISORS ON THE AFFECTED VEHICLES WITH VISORS CONTAINING THE CORRECT LABELS.
