2007 Nissan Titan power train problems

“The rear differential and axle has an inevitable failure with no warning lights or much anything else besides some possible noises! The vent designs are terrible it causes overheating and internal turmoil over time seals start leaking, bearings and internal gears Get weak from over hot /cold repeated cycles allowing moisture to build and accumulate in the 3rd member where it’s supposed to be completely sealed and dry other then gear oil to lube and maintain proper function. My personal and current experience is I’m without my truck, missing work and very . Very thankful that it didn’t lock up on the highway/freeway that I drive too and from work about 85 miles daily! The best part is there’s no fast cost efficient resolution! the differential open carrier with spider gears held in place by a shaft pin and tiny 8 mm bolt that broke causing the pin to slide back and forth (pinball effect) into the ring /pinion, side gears, spider gears untill it either gets jammed in the gears and instantly locks up or slowly fractures away untill gears held by nothing, collide causing catastrophic failure! I Happened to notice the inside of rear wheel wet because when I was…”

“MY REAR DIFFERENTIAL HAS FAILED UNDER NORMAL OPERATING CONDITIONS, ALMOST CAUSING ME TO WRECK. APPARENTLY, THIS IS NOT A NEW ISSUE WITH THESE TRUCKS. I WAS DRIVING 50MPH WHEN THE REAR END MADE A POP AND I LOST THE ABILITY TO DRIVE.”

“THE REAR AXLE SEALS ON MY 2007 NISSAN TITAN CONTINUE TO LEAK GEAR OIL. I HAVE REPLACED THE SEALS THREE TIMES INCLUDING PURCHASING AND REPLACING THE ENTIRE AXLE SHAFT, SEAL AND SPACER ASSEMBLY ON THE THIRD TIME. THESE WERE 2 AXLE SHAFT ASSEMBLIES WHICH COST ME OVER $1000. I HAVE ALSO INSTALLED A BREATHER TUBE ON THE REAR AXLE AND INSURED IT IS ALLOWING AIR TO GET IN AND VENT THE REAR AXLE. IT'S BEEN A FEW MONTHS AFTER INSTALLATION AND THE SEALS ARE LEAKING AGAIN. MY REAR BRAKES AND PARKING BRAKE ARE SOAKED WITH OIL AND THE PARKING BRAKE NO LONGER HOLDS THE TRUCK IN PLACE WHEN PARKED ON A INCLINE/DECLINE.”

“HAD TRANSMISSION SERVICED AND ABOUT 5000 MILES OR LESS LATER TRUCK STARTED HESITATING AND FINALLY STOPPED. INVESTIGATED AND FOUND TRANSMISSION FLUID AND ANTIFREEZE UNDER TRUCK. HAD TOWED TO NEAREST AMMCO STATION AND THEY DIAGNOSED PROBLEM AS ANTIFREEZE IN TRANSMISSION SMELLED BURNED AND SAID A COMPLETE RE-MANUFACTURED TRANSMISSION WAS RECOMMENDED SINCE ALL OF THE TRANSMISSION COMPONENTS HAD BEEN EXPOSED TO THE ANTI-FREEZE AND WERE BURNED OR OVERHEATED. TALKED WITH NISSAN OF GASTONIA NC. AND THEY STATED THEY COULD INSTALL A NEW RE-MANUFACTURED TRANSMISSION AND RADIATOR AND EXTERNAL AFTER MARKET TRANSMISSION FLUID COOLER FOR 5,100 DOLLARS WITH A 12 MONTH 12,000 MILE WARRANTY. THEY SAID THEY HAD A LARGE NUMBER OF FRONTIER, XTERRA, AND PATHFINDER PROBLEMS WITH THE INTERNAL TRANSMISSION COOLER INSIDE THE RADIATOR FAILING ALLOWING ANTI-FREEZE TO LEAK INTO THE TRANSMISSION AND DESTROYING IT. THEY SAID THEY HAD NOT SEEN THE SAME PROBLEM WITH THE TITANS ANS ARMADAS. THEY HAD A CAMPAIGN TO HELP OWNERS OF THE OTHER MODELS BUT NOT THE TITANS OR ARMADAS. THE SERVICE MANAGER FOR NISSAN OF GASTONIA SAID THEY COULD LOOK AT MY TRUCK BUT THERE WOULD BE A DIAGNOSE FEE IF I DIDN'T…”

“REPLACE PASSANGER SIDE AXLE SEAL AT 94000 MILES. NOW I HAVE A DRIVER SIDE AXLE SEAL LEAK AT 105000 MILES. SEEMS TO BE A PROBLEM AFTER LOOKING AROUND ON THE INTERNET.”

“ON TWO SEPARATE OCCASIONS THE LEFT AND RIGHT BACK AXEL SEAL STARTED LEAKING OIL ON TO THE BACK BRAKES AND WHEELS. THE SEALS AND BACK BREAKS HAD TO BE REPLACED BOOTH TIMES WOULD NOT PASS STATE INSPECTION BECAUSE OIL SOAKED BREAK PADS BREAKS HAD REDUCED STOPPING POWER.”
