Rear axle seals leaks. Please report.

My 05 rear pass failed at 13000. Fixed no hassle. Reported.

Second failure on my 04 4x2. 2.94 This time the whole axle was replaced with one built 6-20-2007 !

i just took mine in to the dealer for the 30k mile servicing, and for them to replace both rear seals, but they said something got past the seals and scored the inner axle housing so they are ordering a brand new rear end. i asked them if they can order an '05 version with the finned diff cover and they said that they would take care of it. not sure if nissan would issue a plain 04 axle, so thought i'd be proactive in asking for the upgraded axle.

I have just over 15k on my truck and my seal is leaking...
If the truck has never seen a dealer for service will it be covered by the warranty?

My seals were found leaking when the vehicle was approximately 2000 miles out of warranty. It was discovered when I brought Titan to Dealer to check brake judder for the third time. Dealer reported judder was actually rear trans-axle that was damaged from leaking fluid through seals. Nissan refuses to fix even though this is a well documented problem. Nissan customer service is anything but. Keep reporting this problem to force a recall!

My CC is at the dealer for the second driver side axle seal.
They called me today and said they replacing the rack and pinion and the annoying seat squeak will go away with the new seat they are ordering, blown right front speaker and the TPMS isn't working. Yes I gave them a list at 29,995 miles. I hope they just change out the axle, I know it will fail again. The new seal was leaking less than 2000 miles after install.

Had my LR seal replaced this past Thursday - 24,539 miles.

Looks like my Rear Passanger seal is leaking - it was in two weeks ago for an oil change and to get my bed bolts and spacers fixed and they didn't notice it. Hope it is covered by the PT warranty as I am over the 36 moth one.

my rear driverside failed at about 55k

so i saw the link to the site to report the problem but i dont see where i can report a problem
can anyone help me

i am convinced that the leaks are coming from the pressure build up inside the axle, both vaccum and release. the one way little crap *** check valve that nissan decided to use for a vent valve may be doing an ok job at releasing pressure, but what happens when the diff cools down and all the pressure inside has been released? the check valve is not letting air back in.... all other trucks have a hose that runs up under the bed, why not the titan? i ran my own vent tube up to the fuel tank. we shall see if this has any effects on the longevity of my axle seals...

I agree with your suspicion. I have a '4KCXE, no leaks yet, but I plan to do the axle vent mod, add an aluminum cover and replace the fluid with synthetic this fall.

Should be covered under the warranty. If they say it isnt just go to a different dealer.

I just blew both axle seals at 25,000 miles. I know they just blew cause I towed about 10-11K lbs this weekend for about 30 miles. Then I noticed a oil spot on my garage floor. Easily noticable casue its a brand new house.

Have already had driver side replaced.......just looked under my truck this weekend and noticed the passenger side is blown now!!!!!! ARRRGH!!!!

Took my 04 KC LE OR BT in for 30k service. I had noticed some oil drops from the engine area on my garage floor. Service manager called me back and said the fromt diff pinon seal and right rear axle seal were leaking. He stated the axle seal must have just started leaking. Both seals were replaced under warrenty and they also replaced the axle bearing. Had to leave the truck overnight for the work to be completed. Had a Sentra loaner for the night. No hassles from the dealer, just great service.

Could it be the vent tube not venting correctly do to over fills duirng diff oil changes?

I think vent failure may indeed be the case. If the check valve gets plugged, I think the axle seals handle the venting. The people who replaced the diff vent check valve with a vent hose with a fuel filter on the end don't seem to be blowing axle seals.

Thank

Not up on this one myself but Welcome to TT and someone will help you.

My passsenger side seal was leaking in June, they told me it was due to overfilling the diff. I told him I don't think that is right and I would keep an eye on it. Well, Friday at 59,952 miles, I noticed it was leaking quite a bit. Went straight to the dealer and had the receipt from June with their comments. He scheduled me for this Wednesday. The left one is wet, I'm going to take a photo of both sides and try to convince them the left one will leak soon and hopefully they will fix it also. Does the vent filter get clogged with oil and stick? Or does it get hot and stick? Should it be cleaned regularly to prevent build-up or just do the mod with vent hose to prevent further problems?
