2005 Nissan Titan was driving down a rural road. Stopped on the side of the road and when to resume driving. When left tires went back on pavement the whole truck shuddered and the rear end (differential, spider gears, etc) basically blew up. Truck was half in the traffic lane. A new rear end is being installed with oem parts.

There was a noise from the rear of the truck and an odd odor. It almost felt like a transmission slip once in a while driving. I drove it home as the noise was getting worse and had it towed to the dealer. Their tech drove it off the lot to "check it out" after I told them about the problem and that it was getting worse. The rear end blew out and sprayed fluid all over the undercarriage, the back of the tailgate, everywhere. The dealer just said it had to be replaced. Period. This truck is well maintained by the same dealership and I am told that the rear end/differential is sealed at the factory and is not a part of a maintenance item. It is not used for towing, off roading or anything else like that. I am the only one who drives the truck. I think it would have been very dangerous had it gone out while I was driving it. The dealership had to have it towed back to the shop. It is my understanding that this is a rather common problem based on the complaints that have been filed. It is also an expensive problem at $2300 in my estimation. I requested that they keep the part for further evaluation.

Both rear axle seals leaking.

- Lucama, NC, USA

2005 Nissan Titan crew cab 4X4 with off-road package, within 10,000 miles there were loose bolts on the transfer case. At 38,500 miles the left front differential seal failed and leaked. At 39,800 miles the power steering hose went bad and leaked. At 51,000 miles the circular clip on the axle at front left differential deformed causing axle to begin to fall out of vehicle!!! thankfully all has been covered under our extended warranty, and dealerships have replaced parts, but when it runs out these will come from our pocket, and no one can guarantee the new parts are not just replacements or any better. This could have resulted in death or injury to us or someone else had that axle fell from vehicle, and could occur again.

While driving my 2005 Nissan Titan SE crewcab 4X4 this past weekend, I heard loud banging noises coming from underneath the truck. Shortly thereafter, while making a left turn (at low speed), I noticed the left rear tire locked up completely. This same symptom continued through the next day so I scheduled an appointment and dropped off my truck this morning (Tuesday, November 16, 2010) at the nisan dealer in melbourne, fl. The dealership told me I needed to replace the entire rear differential and it would cost me around $3,400 plus tax. I only have 79,732 miles on the truck, don't use it to tow, and don't off road with it. I told the dealership this was ridiculous because I had a Dodge Ram 1500 that I drove until about 176K miles and it never had a problem like this. The dealer had no answer... I did some online research and noticed this is a recurring theme for 2005 Nissan Titans. I have a call into a lemon law attorney to see what can be done since I don't have $3,400 plus tax to throw away on a Nissan defect.

The rear axle seal on my Nissan Titan was leaking oil on the rear brakes and the fluid level was extremely low. Not sure how often this failure occurs, but now that I am aware of rear axle seal leak problems I will monitor for the failure. The local Nissan dealership replaced a bearing, spacer, and rear oil seal. After researching Nissan Titan rear axle seal leaks there appears to be a trend of rear axle seal failures. The problem needs to be addressed by the manufacture before serious accidents occur.

2005 Nissan Titan SE 4X4 - requires an entire rear end replacement. No known events leading up to the failure; rear differential was making major banging and grinding noises. Mechanic found it to be full of metal chunks and shards due to a gear failure. This then led to a chain reaction damaging the majority of the rear axle components. Truck has not been repaired yet, but Nissan tells me that it will require a whole new rear end costing almost $4000. I can ask that the service dept. To hold on to the old parts once the repairs are performed.

Continuing problems with 2005 Nissan Titan. Current issue is failing rear axle. I have complained numerous times about this problem I.e. whinning, clunk but have been told that this is normal as vehicle ages. Indicated to local dealer problems reported with failing axles, and axle seals and axle breather problems. They indicated they were unaware of very many such problems. Noise and clunk became worse and I began to investigate via web and through my organization membership (club Titan) and discovered a large number of customers with similar issues. Back to local dealership who finally admitted known issues with axles. Past warranty at this point, they recommended contacting Nissan North America. Called and described issues, they assigned file # and asked me to obtain additional diagnosis (which I had to again pay for) and information about any previous Nissan vehicles owned. Before I was able to obtain the requested information, Nissan called back and denied any assistance citing age/mileage of vehicle. I indicated that this has been an ongoing problem, not just something that has occurred after the warranty. They called back several days later and indicated that there is no record anywhere of any complaints on my part regarding the axle problem. Seems strange that other history exists (brake problems, recalls, etc.) on my vehicle, but oddly "nothing" about axle problems. We are moving soon, and I cannot afford the out of pocket repairs, but I cannot put my family at risk of serious injury or death.

I have a 2005 Nissan Titan 4X4 with the off road package. On the 3rd of October 2010 I noticed when I took a left turn and accelerated through the turn I heard a popping sound and the rear of the truck hopped. On the 4th I took it to the Nissan dealer to trouble shoot the problem. I was told the rear differential had broken teeth and it is a recurring problem. The truck only has 44,000 miles on the odometer. My factory warranty expired in June 2010. First time failure has occurred. The extended warranty company evaluated the problem and sent a used part to the repair facility to correct the problem. I am currently waiting to have it replaced and returned to me.

Rear wheel seal leak. Just started and looking to repair.

- Copperton, UT, USA

The contact owns a 2005 Nissan Titan. The contact was driving 15 mph when the vehicle exhibited an unusual bang from underneath. The vehicle was towed to an authorized dealer where the contact was informed that the entire drive shaft fractured from the vehicle and the rear differential had locked. The dealer repaired and replaced the drive shaft, rear differential and the rear seal transfer case. The dealer stated that the front differential pinion flange fractured, causing the failure. The failure mileage was 89,951 and the current mileage was 93,253. Updated 01/20/11 updated0 3/24/11

I have a 2005 Nissan Titan le crew cab 4WD pickup truck and just experienced a dangerous failure of the rear differential. After some initial thumping sounds emanating from the rear of the vehicle during turns, I was turning into a busy intersection when the entire rear end locked up momentarily. I was able to limp to an auto repair facility about a block away. After inspecting the vehicle, it was determined that the gears in the rear differential had failed (teeth broken off). Vehicle is currently being repaired at a cost of over $3,000. I will save the failed part. After research on the web, this appears to be a very common and expensive occurrence. Given the nature of the failure (rear wheel locking), I was almost rear ended by another vehicle behind me.

2005 Nissan Titan differential failure happened for no apparent reason just after starting out in the morning leaving the driveway. I am told by the dealer that the differential will have to be replaced. Differential was replaced 30,000 - 40,000 miles ago by a different dealer service facility when leaky seals were serviced but not for a differential problem. I am assuming that the differential ring and pinion gears, gaskets and lub will be replaced.

2005 Nissan Titan truck requires rear differential replacement. Local dealer denied this is a common problem. This is refuted by the number of complaints filed under the lemon law bill as follows: www.lemonlawclaims.com/Nissan%20titan%20differential%20defect.htm Nissan usa should recall this vehicle for this know defect before someone is injured or killed.

I was driving home from work in my 2005 Nissan Titan (SE crew cab 4X4 off-road edition with tow package) and started hearing a loud metal on metal sound from the rear of the truck. I also could feel a large jolt when accelerating and braking. I took the vehicle to the local Nissan dealership the next morning and they said I needed a new rear differential, and that I also needed to replace the seal on the front differential. They told me that it would cost $3,500 to replace the rear differential and $400 to fix the front differential. The truck has only 67,000 miles on it, and is out of warranty. I have had all the recommended services on the vehicle, and do not use the vehicle for off-roading, nor do I use the vehicle to tow. Nissan said they would only contribute a thousand dollars toward the repair. The dealership ordered the parts today. This is yet another Titan to add to the rear differential problems list.
