2005 Nissan Titan - 4WD 50,423 mi,
This rear axle is mis-designed from the start it eats axle seals like candy. The axle shaft is supported by a single tapered roller bearing. Any moron knows it takes 2 tapered roller bearings to support a load. Basic engineering tells us that this single bearing set up is crap.why there has not been a recall is beyond common sense.they recall crap like wires and fans but let this ride. Where is justice... I am replacing mine this time for the last time. Then I will let them leak and saturate the brakes. Then ride the brakes hard down mountains until the piece of crap burns to the ground. Then buy a real truck like a gm product!"!!! There is a street justice recall. This makes the third set of seals and breathers evev though the breathers are kept clean.

When vehicle had 62000 on it I took it to the dealer in Traverse CITY and told him about the vent problem on the rear differential the service manager said he never heard of this. I told him I wanted the vent replaced and he said the mechanic replaced it and I was charged becouse it was not pluged. At 90000 8 months later the pinion bearing started making noise and I took it to a local mechanic he opened the pig and it was full of moisture and he said the vent was never replaced we tried to get parts from nissan and their fix was to replace the whole rear end for 2000 dollars my mechanic found a outlet in Tennessee that just started manufacturing complete seal and bearing kits for this Dana rear end. He mentioned this was a comon problem with Nissan Titans and thats why they started to manufacture these kits. My mechanic said another 100 miles and I would have wiped out all the gears in the rear end. I would think this was a safety issue but Nissan in Traverse City, They have another dealer in Grand Rapids same owner, didnt think so. The seal and bearing kit will save you 1800 bucks so dont let them tell you they have to replace the whole differential.

Both rear seals are leaking on my truck. Quoted over $700 to replace seals. Have read about so many people having the same problem. I can't believe Nissan hasn't had a recall. A lot of people have had to replace at least two times.
Right axle seal was replaced at 37,000, again at 93,000 and is leaking again at 137,000. Totally unacceptable costs associated with keeping this vehicle road worthy.

Fluid running down near the rear brakes I have filed complaints with nissan and https://www-odi.nhtsa.dot.gov/VehicleComplaint/index.xhtml. still waiting to hear from NHTSA

Started seeing fluid behind rear wheels at about 40,000 miles. Keep filling differential fluid every few months since can't afford work done. Finally found mechanic that will replace rear seals/breather less so hope there's no extra damage when they pull it apart. Why doesn't Nissan warranty this problem??? Or at least offer compensation due to design flaw. Dealer wants $35 a piece for seals...

In 2014 had my transmission and radiator replaced due to a recall.. Year later I was driving on the interstate and heard a loud pop and grinding noise. Made it to the dealership and it was leaking and smoke coming out the back. They told me I needed to replace the whole rear differential. New $3,000 or used $2,100... They said I hit something that put a whole in the seal!!! Had my truck towed to my house had my neighbor mechanic look at it and there was no whole or damage to it, seal was missing... Nissan needs to make it a recall so many problems and people spending money to attempt to fix the problem. Ugh!

Rear end started leaking then within a few days blew the seal. Luckily I was close to home so no long further damage. Replaced seal and back on the road. Including the cost of the socket I bought, the entire repair was less than $50.
