Loud pop coming from underneath truck during backing up and turning. Later same day notice repeated loud pops during tight turns to the left. Drove slowly to Nissan dealer this morning with pops happening driving straight. Dealer listened to pops and without any further diagnosis told me they will order new differential under warranty. Failure of rear differential in my opinion at only 52,221 miles is unacceptable. My power train warranty will run out at 60,000. Dealer will provide 12 month 12,000 mile warranty on new differential and claims that it will be covered until 64,221 miles. I am now worried that the new unit could fail unexpectedly and cause future excess damage and a possible stranding or worse an accident at speed. I hope that it doesn't take my death or someone else?S to have the failure rates looked at by your organization.

I was about to pull into a main thorough fare from a side street going across all lanes to turn left. When I pressed on the accelerator of the vehicle I felt a sudden judder from the rear and a big cut in power. I almost got hit. I was able to continue going but there was popping noises coming from the rear. The dealership is replacing the rear axle and diff. They will furnish me pictures of the old unit.

Failure of differential on my 2005 Nissan SE crew cab P/U. the differential just failed after engaging the 4WD on the fly going about 25mph on a level service nothing out of the ordinary, it just failed. My vehicle had hardly ever been used of road and only has a 35,000 miles on it. I don't drive it hard and it is exceptionally maintained. This makes me wonder if I should have purchased a Toyota Tundra or a Chevy Silverado.

Own a 2005 Nissan Titan 5.6 le 4X4 offroad and tow package. On 5/29/07, I was pulling my travel trailer and made a turn, the rear end made a loud and truck shuddering thump. Afterwards, everytime I accelerated or turned, the rear end would thump and shake the entire truck. I took it to a dealer and was told the rear end needed to be replaced. This was a known issue. I was in richmond, va but live in NJ, so I decided to try to get it home. Put it in 4X4 hi mode and made it. Dropped it off to Nissan dealer in NJ, they are replacing the rear end now, under powertrain warranty.

Early December 06 - I noticed fluid under front differential. Investigated and found that stub shaft (which bolts to front cv) had pulled out of the front differential on the driver's side. Pushed it back in but oil seal had been damaged so it was still leaking. Took it into the dealership but they wouldn't cover under warranty due to aftermarket lift (even though they sell a version of my truck with this lift installed by the factory). Paid $380 to get a new seal installed. Late December 06 - 2 weeks after repair I found fluid under the truck again. Pushed it back in and leak stopped. January 07 - while in Mexico, my wife was driving 4WD on hard packed sand. I heard a loud bang and when I looked under the truck I found that the same shaft was out again. Turns out the shaft has splines and a small circlip to hold it in place. The circlip is undersized so it only takes about 1 pound of force to separate the 2 pieces. This most recent time occurred under load so when the shaft shot out, the splines got damaged. Since I was a day's drive South of the border I had to file and then hammer the shaft back into place. Nissan denied my warranty, again blaming the lift for the problem. I found several other people online who have had the same problem, most without lifts. I talked to a technician at a Nissan dealership in Oregon and he confirmed that he has seen several front differentials with this problem. He suspected that the cv joints don't stretch as well when weather is cold thereby pulling the stub shafts out when the wheels are turned. Most vehicles he had seen were stock. He also said that Nissan had a redesigned differential that the tech's are supposed to install when this happens. I contacted Nissan customer service and made an appointment with a factory rep. Nissan finally agreed to do a one-time front differential replacement under warranty.

Went to the beach, next day I noticed a terrible, noise/feel from the rear of the truck, took it in and they said it's the rear differential again...

While turning out of a parking space, multiple loud clunks came from the rear of the truck and the truck hesitated as if the rear axel was binding. Upon review it was determined that the rear differential was binding whenever the wheels became out of sync (steering left or right even slightly). This could have been disastrous if occurring in the street and not a parking lot. I have researched and found many complaints of the same issue. Something must be done to prompt Nissan to acknowledge this problem and fix it. This is a dealer repair only issue as no aftermarket replacement parts can be found. With Nissan replacement differentials at $3000 each, I'm sure Nissan would not mind keeping a lid on this issue so we can keep buying their parts. It's time something was done before anyone seriously gets hurt when their vehicle abruptly stops in harms way due to a known common failure in the driveline.
