2002 Toyota Tundra Powertrain & Transmission Problems

My original owner 2002 Toyota Tundra Truck was being backed up in reverse with a utility trailer attached up a very, very moderate incline on a driveway pushing the trailer onto a gravel pad ALONGSIDE (parallel) the driveway. As it started to spin gravel the truck was put into a 4 wheel Drive LOW RANGE. This is in keeping with the TOYOTA owners manual publication 0M34417U Part Number 01999-34417 Print date 02-0109-01. We followed the manual instruction on 4 WD operation. Within a few feet the truck stopped as if the wheels had hit a curb and there was no further movement no matter the accelerator pedal position and the engine speed was unchanged as if it was in a stall. All of a sudden there was a loud bang underneath the truck and the truck raced rearward 8-10 feet jackknifing the trailer into a tree and upending the truck and trailer. We contacted Toyota on the incident and they had a third party look at the truck for brake condition, floor mat placement and throttle freedom at the body shop & Toyota closed the complaint file. Toyota IGNORED the circumstances and description of the incident in closing the complaint. We have been a very long time TOYOTA truck family and have owned SIX Toyota 4 wheel drives plus a Lexus all-wheel drive. In doing our own evaluation and investigation we have found that the truck went into a 4-wheel drive "wind-up" or "bind" and found information related on it from ASE Certification sites. NO MENTION of this potential issue is provided in the owners manual! We found that the torque from this can be over 4,000 ft/lb. and possible magnified even more by low range. When this bind suddenly is released the movement can be violent as happened here. Why is this not talked about in the owner manual? Why does Toyota ignore this reality? Indeed, the Toyota Rep. Mr. Ronald Inton said "he never heard of anyone backing up in 4 Wheel Drive"! WHAT?? We have the vehicle, photos, Toyota denial all available for review,.

THE REAR AXEL AND DIFFERENTIAL HOUSING/CASTING IS CORRODED THRU SUCH THAT OIL IS LEAKING THROUGH THE DIFFERENTIAL HUB ONTO THE ROADWAY AND RESULTING IN A LOSS OF GEAR OIL WITHIN THE DIFFERENTIAL AND AXELS. AFTER DRIVING ON THE HIGHWAY THIS OIL WAS OBSERVED ON THE SPARE TIRE (MOUNTED UNDER THE BED) AND UP THE BACK OF THE BUMPER. THE SERVICE REPRESENTATIVE AT ONE DEALERSHIP I APPROACHED TO DISCUSS THE COST OF REPAIR INDICATED THAT THEY HAVE SEEN THE PROBLEM MULTIPLE TIMES. THIS OBVIOUSLY SHOULD NOT BE HAPPENING AND I BELIEVE IT TO BE THE RESULT OF A DEFECTIVELY DESIGNED/MANUFACTURED COMPONENT. I HAVE NOT YET HAD THE VEHICLE REPAIRED DUE TO THE HIGH COST, BUT IT IS NOT DRIVEABLE AS THE DIFFERENTIAL WILL NOT HOLD GEAR OIL.

REAR DIFFERENTIAL IS LEAKING OIL DUE TO FAULTY METAL USED IN MANUFACTURING. DIFF. IS LEAKING THRU RUST HOLES IN HOUSING METAL AND NOT THRU SEALS.

TL* THE CONTACT OWNS A 2002 TOYOTA TUNDRA. UPON INSPECTING THE VEHICLE, THE CONTACT NOTICED THAT THE REAR DIFFERENTIAL WAS LEAKING. THE CONTACT ALSO MENTIONED THAT THE CHAIN THAT HELD THE SPARE TIRE IN PLACE FRACTURED FROM THE FRAME. THE VEHICLE WAS TAKEN TO BROWN'S TOYOTA OF GLEN BURNIE (7167 RITCHIE HWY, GLEN BURNIE, MD 21061 (410) 761-9000) WHERE THE CONTACT WAS INFORMED THAT THE REAR AXLE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 81,000.

WHEN PULLING THE VEHICLE INTO PARK ON A ROADSIDE, THE GEAR SHIFT LEVER SNAPPED AND STOPPED WORKING, MAKING IT UNABLE TO SHIFT GEARS INCLUDING PUTTING THE VEHICLE INTO PARK. UPON REMOVING THE COVER OVER THE STEERING WHEEL, IT WAS OBVIOUS THAT THE GEAR SHIFT LEVER HAD INDEED BROKEN COMPLETELY LOOSE FROM THE STEERING COLUMN.

TL* THE CONTACT OWNS A 2002 TOYOTA TUNDRA. WHILE ATTEMPTING TO START THE VEHICLE, THE CONTACT NOTICED THAT THE GEAR SHIFTER WAS VERY LOOSE. THE CONTACT REMOVED THE TIP OF THE LEVER TO FIND THAT IT WAS FRACTURED FROM THE MOUNTING BRACKET. THE VEHICLE WAS TOWED TO THE CONTACT'S RESIDENCE. THE DEALER (TOYOTA OF VISALIA, 922 S BEN MADDOX WAY, VISALIA, CALIFORNIA 93292) WAS CONTACTED BY TELEPHONE. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 153,000.

THE DIFFERENTIAL HOUSING IS RUSTED SO BAD THAT OIL IS SEEPING THROUGH RUST PITS. THE FRAME IS ALSO RUSTED AND HAD TO HAVE IT WELDED. ALSO LOST THE SPARE TIRE DUE TO RUST.

PURCHASED THE VEHICLE IN FEBRUARY 2017 AND WAS INFORMED BY THE MECHANIC THAT THE REAR END DIFFERENTIAL WAS BEGINNING TO LEAK DUE TO EXCESSIVE RUST. FURTHER INSPECTION OF UNDERCARRIAGE DO TO A NOISE UNDER VEHICLE FOUND THAT THE FRAME AND BODY MOUNT HAD DETERIORATED DUE TO RUST CAUSING A HOLE IN THE BODY MOUNT CAUSING THE CAB TO FLEX AND BOUNCE ON THE FRAME. VEHICLE TREATED BY TOYOTA FOR EARLIER RECALL DUE TO RUST OF THE FRAME AND GIVEN A 5YR EXTENDED WARRANTY. BODY OF VEHICLE IS FREE OF RUST, FRAME AND DIFFERENTIAL HAVE EXCESSIVE RUST MAKING THE VEHICLE UNSAFE TO OPERATE.

I WAS DRIVING DOWN THE ROAD ON A ROAD ~35 MPH WHEN MY REAR AXLE ASSEMBLY LOCKED UP CAUSING THE TRUCK TO ABRUPTLY COME TO A STOP.

REAR AXLE SEALS HAVE FAILED FOUR TIMES IN THE PAST FIVE YEARS. WHEN THEY FAIL, THE REAR BRAKES BECOME COATED WITH OIL, SIGNIFICANTLY INCREASING STOPPING DISTANCE.

FREQUENTLY FROM A PARK POSITION AND THEN SHIFTING AND TURNING SEEMS TO LACK RESPONSIVENESS.

VEHICLE HAS "GROWLING" NOISE COMING FROM FRONT DIFFERENTIAL. NOISE IS ALSO ASSOCIATED WITH VIBRATION IN STEERING AND AFFECTS STOPPING AND ACCELERATION AS FAULTY PARTS BIND IN GEARING. THIS FAULTY EQUIPMENT HAS OCCASIONALLY LOCKED ONE WHEEL WHILE TURNING, FORCING VEHICLE WEIGHT TO ONE SIDE. IN WET ROAD CONDITIONS VEHICLE HAS SLID WHILE CORNERING. MANUFACTURER IS AWARE OF THIS ISSUE, AS SEVERAL OWNERS REPORT THE SAME ISSUE. DIFFERENTIAL IS REPLACED AS A LAST RESORT BY THE MANUFACTURER AND ONLY COVERS THIS FAULTY PART(S) UNDER THE FACTORY WARRANTY. *JS

TL* THE CONTACT OWNS A 2002 TOYOTA TUNDRA. THE CONTACT STATED THAT HE OBSERVED THAT THE REAR DIFFERENTIAL WAS RUSTED AND LEAKING. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 117,000.

WHEN ATTEMPTING TO PUT THE TRUCK IN GEAR TO LEAVE A GAS STATION THE ENTIRE SHIFTER MECHANISM BROKE OFF AT THE MOUNT WITHIN THE STEERING COLUMN. AFTER 1 GOOGLE SEARCH IT SHOWS THIS IS VERY COMMON WITH MY TUNDRA TRUCK (MANY POSTINGS AND COMPLAINTS-ISSUES). I WAS IN A PICKLE TO MOVE MY VEHICLE AND WAS NOT SAFE IN DOING SO. *TR

I NOTICED A POOL OF OIL UNDER MY REAR AXLE. I INSPECTED IT AND SAW THAT THE WELDS WERE FAILING DUE TO EXCESSIVE RUST. I HAD THE FRAME AND BRAKE LINES REPLACED UNDER THE RECALL AND THIS IS CLEARLY RELATED TO THE RUST PROBLEMS (I HAD THE POWER STEERING RACK REPLACE LAST MONTH DUE TO RUST) BUT TOYOTA WON'T FIX IT UNTIL THERE IS A RECALL. I HAD IT REPAIRED (THE WHOLE AXEL REPLACED) AT A LOCAL GARAGE FOR APPROX. $2,340. WITH THE POWER STEERING RACK REPAIR THAT COMES TO ~ $3,300 IN LESS THAN 2 MONTHS. THE GARAGE SAID THEY SEE THESE PROBLEMS ALL THE TIME ON THE TUNDRAS WITH THE FRAME RECALL. *TR

I AM THE OWNER OF TWO TOYOTA VEHICLES. VEHICLE ONE IS A 1992 TOYOTA PICKUP EXTENDED CAB 4X4 3.0 V6 WITH 220,000 MILES ON IT I BOUGHT IT WITH 124,000 MILES ON IT. VEHICLE TWO IS A 2002 TOYOTA TUNDRA SR5 4.7 V8 WITH 47,000 MILES I BOUGHT IT WITH 39,000 MILES ON IT WITH ONLY ONE PREVIOUS OWNER. THE NEW FRAME IS INSTALLED ON THE TRUCK BUT I HAVE NOTICED NOW THAT MY REAR AXLE HOUSING IS COMPLETELY ROTTED AND RUSTED OUT AND LEAKING ALL OVER THE PLACE. THE STRUCTURE OF THIS IS NOT SAFE AND I TRAVEL AN AVERAGE 6,000 MILES A MONTH FOR WORK. MY 1992 TOYOTA TRUCK WITH 219,000 MILES REAR AXLE IS IN BETTER SHAPE THAN THE 2002 TOYOTA. I HAVE SPOKE WITH TOYOTA DIRECTLY AND THEY REFUSE TO DO ANYTHING ABOUT THE SITUATION. THERE SHOULD BE A LAW SUIT AGAINST TOYOTA FOR NOT REPLACING THESE REAR AXLES BECAUSE THE SAME METAL WAS OBVIOUSLY USED ON THE FRAME THAT WAS REPLACED. I HAVE NOW SEEN MANY OF THE SAME TRUCKS AROUND MY TOWN WITH THE SAME PROBLEM AND HAVE READ MANY COMPLAINTS ON THE INTERNET ABOUT THIS RECURRING SITUATION. IT IS IN TOYOTA'S BEST INTEREST TO TAKE CARE OF THE PROBLEM BEFORE THERE IS A CLASS ACTION AGAINST THEM. *TR

TL* THE CONTACT OWNS A 2002 TOYOTA TUNDRA. THE CONTACT STATED THAT WHILE ATTEMPTING TO SHIFT GEARS FROM PARK TO DRIVE, THE HOUSING BROKE AWAY FROM THE SHIFT LEVER. AS A RESULT, HE SHIFTER BECAME STUCK IN REVERSE. THE CONTACT MENTIONED THAT HE WAS ABLE TO MAINTAIN CONTROL OF THE VEHICLE BY ENGAGING THE BRAKES. THE VEHICLE WAS TAKEN TO A DEALER WHO DIAGNOSED THAT THE GEAR BOX HOUSING HAD A STRETCH FRACTURE AND 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 AND CURRENT MILEAGE WAS 137,000.

TL* THE CONTACT OWNS 2002 TOYOTA TUNDRA. THE CONTACT STATED THAT THE TRANSMISSION SHIFT LEVER BROKE LOOSE FROM THE COLUMN INTERNALLY AND BROKE INTO SEVERAL PIECES.. THE LEVER WOULD NOT ENGAGE INTO GEAR AND THE CONTACT INSPECTED THE VEHICLE AND FOUND THAT THE STEERING METAL HOUSING WAS FRACTURED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND THE CURRENT MILEAGE WAS 69,800. UPDATED 10/5/11 *CN UPDATED 10/24/11

TL*THE CONTACT OWNS A 2002 TOYOTA TUNDRA. THE CONTACT NOTICED AN OIL LEAK AFTER PARKING THE VEHICLE. AFTER HE INSPECTED, HE SAW THAT THE REAR DIFFERENTIAL WAS LEAKING THE OIL THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHERE THE CONTACT WAS INFORMED THAT THE ENTIRE AXLE HOUSING HAD RUSTED COMPLETELY, THUS LEAKING OIL. . THE CONTACT CALLED THE MANUFACTURER WHO STATED THAT THEY WOULD CALL HIM BACK AND DETERMINE IF THEY WOULD ASSIST WITH REPAIRS. THE FAILURE MILEAGE WAS APPROXIMATELY 89,000. UPDATED 01/14/11 *BF THE ENTIRE DIFFERENTIAL NEEDED TO BE REPLACED. UPDATED 04/19/11

I OWN A 2002 TOYOTA TUNDRA AND I HAVE HAD APPROXIMATELY FIVE OCCASIONS WHERE I HEARD A CLUNK WHILE DRIVING THE TOYOTA TUNDRA AS IF THE TRANSMISSION WAS SLIPPING DURING THE MONTH OF JULY 2010. ON AUGUST 13, 2010, I WAS DRIVING APPROXIMATELY 75 MPH WHEN I HAD DRIVEN THE TUNDRA APPROXIMATELY 200 MILES, I PULLED OFF OF THE HIGHWAY TO REFILL WITH GASOLINE AND AS I SLOWED DOWN TO THE PUMP, THE TUNDRA BEGAN TO EXCESSIVELY SHAKE AND STALLED. I THEN STARTED THE VEHICLE UP WHICH STARTED WELL AND I CUT IT OFF TO REFILL WITH GASOLINE. ONCE I BEGAN TO TAKE OFF, THE TUNDRA BEGAN TO SHAKE AGAIN AND STALLED, NOT MORE THAN 1/10TH OF A MILE FROM THE PUMP. I STARTED THE VEHICLE AGAIN AND WHEN I PUT THE TUNDRA IN GEAR, THE TUNDRA CONTINUOUSLY STALLED NO MATTER WHETHER IN DRIVE, NEUTRAL OR REVERSE. EVERY TIME I STARTED THE VEHICLE AND PUT IT IN A GEAR, IT WOULD STALL. THE VEHICLE WAS TOWED TO MY RESIDENCE WHICH WAS APPROXIMATELY 100 MILES. MY FAILURE MILEAGE WAS APPROXIMATELY 89,000 MILES. *TR
