If you have had a rear axle seal failure or blown diff, please report it to the NHSTA. We need to get something done so that we do not have to pay for this out of pocket once our warranties are expired. This is a safety issue because the fluid leaks all over the brakes, and can cause brake failure. My seal went out in March and was replaced. Look under your truck on the back of your brakes to see if it looks "wet". It's hard to miss if you look. Nissan will repair under warranty, but this has been a common issue, so it should be addressed so that we have a permanent fix. If you don't fix it, it will keep leaking until all your rear diff fluid is gone, which will cause your rear diff to break. There have been a few "home-made solutions" to try to fix this issue, but this is something we should not have to deal with.

Please report your leaks at https://www-odi.nhtsa.dot.gov/ivoq/

Report your failure under the following category
POWER TRAIN:AXLE ASSEMBLY:AXLE SHAFT:SEAL

If your entire rear diff failed, please report it to the appropriate category.

Mine failed at 8000 miles when my suspension was still stock.
Your Complaint Information is successfully submitted.
Your Confirmation number (ODI Number) is: 10185695

Here is what my complaint looked like when completed:
Results : 1 | All records displayed
Make : NISSAN Model : TITAN Year : 2006
Manufacturer : NISSAN NORTH AMERICA, INC.
Crash : No Fire : No Number of Injuries: 0
ODI ID Number : 10185695 Number of Deaths: 0
Date of Failure: March 9, 2007
VIN : 1N6BA06A16N...
Component: POWER TRAIN:AXLE ASSEMBLY:AXLE SHAFT:SEAL
Summary:
LEFT REAR AXLE SEAL BLEW OUT AND LEAKED DIFFERENTIAL FLUID. DIFFERENTIAL FLUID LEAKING ON REAR BRAKE ROTORS WHICH COULD CAUSE BRAKE FAILURE, WHICH WAS A MAJOR SAFETY CONCERN TO ME. AT TIME OF FAILURE AT 8000 MILES NO SUSPENSION MODIFICATIONS HAD BEEN DONE TO VEHICLE. ALSO, THE REAR DIFFERENTIAL OIL WILL SLOWLY LEAK AND CAUSE THE REAR DIFFERENTIAL TO LOSE FLUID AND FAIL. NISSAN REPLACED SPACER AXLE (43070-7S200), BEARING (40210-7S210), AND SEAL (43252-7S200). AS THIS SEEMED TO BE A VERY COMMON PROBLEM WITH THE NISSAN TITAN, NISSAN SHOULD ADDRESS THIS ISSUE AND OFFER A PERMANENT FIX SO WEOULD NOT BE FACED WITH THE SAFETY ISSUE IN THE FUTURE. *AK

Here is what my rear axle seal failure looked like:


Thanks guys.

Rear diff dead at 24k

My rear diff locked up at 24k and was replaced hub to hub by Nissan under recall. Its an 05 now ith 70k so its been almost 2 years, but if it was a defect then, its still a defect. No issues, no leaks since.

Its been 2 years......

When my 05 diff locked up (no warning, in the middle of a blind intersection on a curve) I dragged it out and to the dealer using front whell pull in 4wd. When I got to dealer he explained that they were having many issues and a recall was issued. I had to wait a week to get one from factory. I didn't see a notice but they have three in crates hub to hub sitting on the floor in the shop. I was there today.

Same [email protected]*t happened to my 05 Frontier Nismo Off Road, my kid at college. Threw it in a fence and tore up fender and door. Boy swore it suddenly just did a 360". I open the whoop on him for squirrelin', towed to body shop and then to local dealer. Dealer replaced that rear hub to hub, Nationwide subrogated and I got my deductible back, 'cause defective rear caused the whole deal. As for the boy he probably needed the whoop for something I didn't know about anyway. Again I didn't see a notice, but Nissan paid.

I know your on top of this stuff, but it just was what it was. I'll look back and see if I can dig up paper to send you.

If the brakes get very hot and the differential fluid leaks on them, doesn't that pose a fire hazard? I don't know what the flashpoint of the fluid is.

It's definitely a safety hazard.
My parking brake wouldn't hold when my Titan's Rt. rear seal went. I always put it in park anyways after setting the brake, but I like to have the brake hold the truck.

But it is possible for someone to do a neutral and parking brake ... leave the truck running scenario and have their Titan go on a rampage.

I would think at least a couple of the blown rear differential happened due to low levels caused by leaking seals.

Anyone know why it is usually the Rt. rear?

Btw, I did the Fed. complaint.

They replaced the whole rearend because the seals were leaking, or you had other problems.
