Rear axle seal failure destroyed parking brake shoe parking brake will not engage.

- Jacksonville, FL, USA

While driving the truck in 2wd I heard a very loud clunking (metal on metal) noise coming form the front of the truck. After reaching home, I realized that the front axle was falling out of the front differential. I jacked the truck up and dropped the front diff pan. This is where I realized that the clips hold in the front axle have failed and broke in two. This is a huge safety concern, had I been traveling down the highway I could have been killed if the wheel came off. I researched online and discovered this a common problem.

Within a period of 14-15 months both rear axle seal assemblies failed, one each on passenger and driver side of the rear axle. According to national tire & battery the entire axle assembly is required to repair or replace a seal that is leaking, at a cost of approximately $1000 each time. This seems quite unreasonable and excessive to replace an axle that is in perfect operating condition when the only issue is with a rubber boot (seal) that is leaking fluid.

2006 with 2000 miles; rear differential made a loud gear whine sound when in un-loaded de-cel. Took Titan back to dealer. Dealer replaced differential under warranty (2000 miles, one month after purchase). At 115,000 miles in July of 2011, replaced rear axle seals (no warranty). Now, September 2012, at 133,000 miles. The slip and brake lights illuminate when differential gear oil is cold. Once warmed up, lights go out and stay out after Titan is shut down and restarted warm. Changed differential oil every 7500 miles with 75W 140 synthetic oil per maintenance guidelines. No additives called for or used with gear oil changes. According to the owner's manual the lights (slip and brake) indicate that the anti-lock brakes and limited slip are not operational when lights are on. Differential repair/replacement required to re-gain ABS and lsd features. Not sure if the ultimate failure mode is 'graceful' or not.

2006 Nissan Titan 4X4 currently with 80,200 miles. Left and right rear axle oil leak. At approximately 65000 miles, during a transmission oil change at a Nissan dealer, mechanic noticed the passenger rear axle was leaking. The service representative stated it would be about $500 to repair. He also stated that no recall had been issued. After having the engine oil changed on July 2012, I noticed my driver side rear axle leaking now. Several similar issues have been posted online. Nissan should push the manufacture to have this hazardous issue resolved very soon and Nissan should replace the seal at no cost or at a low discounted price.

My 2006 Titan started vibrating like running over rumble strips on side of highway. Took straight to dealership. Was told that the cooling system split and contaminated the transmission. I had to have the transmission and radiator replaced $7313.56. There was no warning or anything. After reading many complaints for the same thing on other Nissan vehicles, there needs to be an investigation and a recall on the cooling system that can cause this amount of damage.

Had truck in shop for exhaust pipe falling off and it was brought to my attention that both the left and right rear axel seals and bearings are bad and need to be replaced. The axel had been leaking fluid onto my tires and brakes which could have resulted in brake failure or fire. Nissan will not warranty the rear axel repairs. This is the second new Nissan factory axel to be installed on this vehicle since purchased new in 2006. It is currently having the rear seals and bearings replaced at my expense. This seems to be a common problem with the Nissan Titan model and should be recalled.

Noticed the drivers side rear axle seal is leaking fluid. Could potentially cause the axle to seize and/or brakes to fail. This is a major safety issue and should be recalled. Luckily I had a mechanic notice it before I got into an accident. This is a dangerous and expensive problem that should be covered by the manufacturer due to poor quality parts.

Both rear axle seals are leaking and need replaced. I have never pulled anything with this truck and at 70,000 or even sooner, I'm not sure when it started leaking, you should not have to pay for replace rear axle seals.

Right rear wheel seal is leaking badly noticed at 65000 miles but it looks like its been leaking for a while. This problem seems to be frequent and it also seems to be a safety issue it oil leaking onto the brakes.

2006 Nissan Titan rear axle seals began leaking. Vehicle has never been off the pavement and has had all maintenance performed by the owner manual list.

I noticed an exhaust leak on my truck. Took it to a reputable exhaust shop, they told me their was a crack in the converter and I needed to take it to the dealership. After checking the web I realized it was under warranty (80000 on exhaust emissions) my truck only had 65K. They replaced both manifolds as they were both cracked. This repair would have cost me 2500.00! after seeing this was a common problem with the Titan trucks, I think this should be addressed. Also the dealership told me I had a front differential leak which was the pinion seal, this repair will cost me 300-500.00. Of course its not covered under warranty so I will have to pay this. After seeing this is also a common problem, I feel Nissan needs to correct this issue as it is a safety problem for both me and fellow motorist. My truck has 65,000 miles and is babied! total repairs would be around $3000 for the manifolds and the differential, I feel something needs to be done as this is an ongoing issue.

Rear axle seals leaking gear oil. Replaced by certified mechanic twice and the leak persists.

I was having my vehicles front differential fluid changed and the service technician noticed 2 cracks around the axle housing. Upon further inspection the housing was damaged enough to wear it could leak and cause failure.

Both rear axle seals started leaking all over my brakes and inside the wheel well causing poor breaking ability. I called the Nissan dealer and they told me this is a common problem with Titans and that they no longer recommend replacing just the seals but instead the whole axle. The tech (who told me he had 20 yrs with Nissan) said that when they used to just replace the seals people would have to come back 6 months later because the seals would blow again. All of the posts online say that it is a result of an improper venting system that does not allow for the release of negative pressure. If this is such a common problem, and Nissan knows that it is, why don't they do a full recall? this is a very dangerous problem that can cause brake failure.

Rear axle seal, driver side, and soon after, the passenger side as well, failed. Differential fluid leaked out onto inner wheel surface, brake parts, and immediate area creating hazardous conditions. This is a widely known problem for Nissan Titan owners and Nissan is, and has been, well aware of this problem and has not offered a design solution to my knowledge. Nearly every Titan experiences this seal failure at some point. Some while still under warranty, (which typically get repaired by Nissan) but as for the rest of us who are beyond our warranties, we are left with this hazardous condition and a big repair bill. **this should be a recall, or at least repaired by Nissan at their expense. Its my understanding that there was a technical service bulletin outlining the issuefor Nissan mechanics. Please help**

The contact owns a 2006 Nissan Titan. The contact stated that the rear differential cracked while driving 55 mph and caused differential fluid to leak from the rear driver side tire. The contact took the vehicle to the dealer where the dealer advised that the rear differential needed to be replaced. The vehicle was previously repaired for the same failure but to no avail. The failure mileage was 64,000.

My 2006 Nissan Titan has an axel seal failure on the drivers side rear, differential fluid is leaking onto the rear brakes causing reduced braking and also the potential for axle/differential failure. Nissan refuses to address this design flaw. They have a re-engineered replacement axle shaft and seal at a cost of about $800 per side. This should be a recall not $1600 out of my pocket to fix. Will Nissan and ntsb wait until there are fatalities before they address this common issue with the Nissan Titans?

Just replaced the rear seals for a Nissan Titan 2006. Problem began at 65,000 miles. I was told that lack of fluid due to leaking could cause the vehicle to lock-up while driving. The internet is filled with complaints regarding this issue. This seems to be a major safety problem. Also had tailpipe issues (dropping from the truck) which is also well documented on the internet and, again, a safety problem. Needs to be recalled.
