Power Train Driveline problems of the 2007 Nissan Titan

2007 Nissan Titan rear differential failed. I noticed a thunk when coming to a stop or starting up from a stop. Upon deceleration there would be a thunk thunk thunk. Tempo would increase or decrease in relation to speed. I turned a corner, felt and heard a very significant clunk/bang, felt like I rolled over a boulder, as I proceeded for another 50 yds, the thunk was hard enough to feel through the vehicle and loud enough to hear from outside the vehicle as evidenced by the stares I got as I came to a stop. Towed it to sheehy Nissan in manassas, va, they confirmed it was the rear diff and replaced it under warranty. Mileage was 42,828.

Bought a used 2007 Nissan Titan 4d 4x4 on 21 June 2011. After driving it for a day, noticed fluid leak around brake and wheel area next to axle on rear driver's side. Took to Nissan dealership who said that it was the axle seal, and both actually needed to be replaced. Have never used vehicle in 4x4 or to tow. Very concerned due to the possibility of the differential locking up at high speeds or towing something and causing an accident. It leaking on the breaks is also has my concern. Hope this can be fixed by Nissan.

Rear axle seal leaking. Replaced at 30k miles under warranty leaking again at 67k no warranty coverage 2k repair.

Prematurely failing inner rear axle seals causing gear oil from diff to get into rear brake calipers and rotor causing increased braking distance. Been replaced once on left and twice on right.

Both rear end axle seals went bad causing oil to leak over rear brakes which lead to brake failure. Complete rear end had to be replaced.

2007 Nissan Titan driver side rear axle seal leaking. Took to dealership and stated it will be fixed under warranty. Seems to be a common problem for both sides in the vehicle along with rear differential failure.

Had informed Nissan two months after purchase at 1700 miles, of loud "clunk" noise in rear axle when traveling over bumps or potholes as well as tightness and noise from the steering column. Nissan stated nothing was wrong with the rear but replaced a defective rack and pinion assembly. During a routine oil change at 34000 miles the differential was found to be leaking from both rear axle seals and the pinion seal. Nissan dealership verified the problem on 6/11/10, replaced both rear axle shaft assemblies, and replaced the pinion seal.

My rear axle seals are leaking and have been for some time. I had them replaced and need them replaced again. They leak all over my rear brakes and I am concerned that this could lead to a potential dangerous situation.

There is an ongoing failure of rear axle seals and bearings in our 2007 Nissan Titan. This results in the slip and brake light burning continuously as well as the rear axle leaking oil. We have had this replaced twice under warranty but it keeps happening. They were changed at 34,712 and 58,205 miles respectively. The lights are on and they are leaking again at 75,209 miles. There is a Nissan technical bulletin on this problem with 2004-2007 Titans. We contacted Nissan and they will not cover a problem out of warranty though it is a manufacturers defect. It appears to us they put cheap repairs in while under warranty and now that the warranty has expired they want their customers to have to pay to fix their design flaw correctly. We have called Nissan corporate about this problem and were given a case number and they were going to investigate and let us know if they could help. After several weeks we were told Nissan would not help us resolve the problem. The leaking oil presents a danger when it gets on the brakes and makes it unsafe as well as they possibility of parts failure in the rear end. I have been on many Titan forums on the internet and this is a very big problem. We are also sending this information to the attorney general of the state of west virginia.

2007 Nissan Titan le, complete rear end failure in the middle of an intersection with an 18' bass boat in tow. I had to be drug about 100 yards to a safe area to get the truck and boat disconnected, ruined a new set of rear tires as the rear end was locked up. Truck currently in shop for new rear end/ hopefully root cause of failure. Luckily no one was hurt.

I noticed a popping in the rear end everytime I changed gears. I took it to my dealer and they ordered me a new rear end, and replaced it.
