Anyone who has had the rear axle seals please report the the National Highway Safety Web Site. Mine leaked so bad I was getting some rear diff oil on the rear brakes. This has become a safety issue and needs to be addressed.

Please if have a leak or had a leak on the rear axle seals, please report. This may help our case should we have seal failure after the warranty expires.

My right rear seal was replaced at 55k miles.....if you let your seal leak so long that it got to your brakes, then that's your fault for lack of attention to details.

No, I think it is Nissan's lack of attention to detail.

Let's get back to the subject of the thread and just report the leaking seals. Thank you.

New rear axle assembly installed today, maybe final fix for seals?

Mileage - 10769 - left rear axle seal leaking, had already installed new finned cover with synthetic oil. Seal replaced.
Mileage - 13022 - left rear axle seal leaking again, dealer replaced seal along with "axle seal sub-housing".
Mileage - 26707 - left axle seal leaking for third time and also "clunk" in drive train. Rear axle assembly replaced. Service rep mentioned wear on spider gears.

Will post this info at nhtsa.dot.gov. Still love this truck, just hope that leaky seals and juddering brakes are a thing of the past.

Thank You. Nissan needs to step up and address this problem just like they did the brakes. It may take awhile but we have to keep on the problem. They need a better seal. Needs to be addressed before warranties run out or we will be paying for it out of OUR pockets.

Mine started leaking recently. Dealer replaced them yesterday. I've already filed a complaint on the NHTSA website. Next!

Thank You. I think we are starting to see that this is common problem with our trucks. They need a better seal because some have reported the replacement seals have failed also.

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 believe that the Tundra's have the same set-up as the Titan. I know GM has the hose that vents somewhere near the gas fill cap. You're right, this could be the problem.

Brought my truck in for front diff driverside axle seal leak and they noticed my rear axle seal was leaking to!

Please report it. Thank You

 

[Herbpov]

They fail because they are weak seals. If we don't get Nissan to step up and fix this problem like they did with the brakes, we're all going to be paying out of our own pockets when the warranties expire. REPORT IT !!!!! They need a new and improved seals.

pass side started leaking a couple days ago...its at the dealer now......sucks to be in a sentra!! no power!!! lol

Seems to me, from all the posts, that the pass side is the first to go. Then the driver's side a little later. Please report it.

Mine is leaking on passenger side. Its all over the inside of the wheel.

I got 77,000 Miles so no warranty for me. Anyone know how to replace these seals? Any special tools needed?

I would check with the service manger first. This is a wide spread problem and just maybe you could get a goodwill repair. I think someone said the cost is around 400.00. That's why need to get these all reported. We need a recall because it could be a safety problem. Wheel bearing has to be drilled off and a new seal and new bearing pressed back on.

The service tech just told me today that nissan has upgraded the seals. They are going to replace both seals even though only one side is leaking.

That would great if it is infact true. Keep us updated and report it.

replacement seal part # on mine was #43252-7S200. Let us know if yours is different.

 

[Herbpov]

herpov--is the part number you have given us from the white sticker near the diff?

white

No, it is the part # of the seal itself.

Here's what my axle seal leak looked like. Since the dealer drained my Schaeffers 267 Moly 80W90 synthetic-blend, (pic shows full synthetics don't climb like the blend does ??? The stuff sure kept the diff cover cool., and put in that Nissan Corp. full synthetic stuff, I think I might be posting on the rear-end failure thread before long. Well I guess a 4-pinion spider gear would be pretty nice, so I shouldn't complain.

They did not drain mine, they just topped it off when they were done. No need to remove the diff. cover that I know of.

 

[Herbpov]

Did they crack off your old bearings and press on new ones on yours?

They had to send the axle, or some part of it, out to a local shop because the did not have a press big enough.

I can tell they took off the cover too, because there is some of that orange high temp RTV showing. I would have used black but no big deal. And they fill with the Nissan synth.

New bearing and new seal. Did not remove diff cover.

 

[Herbpov]

Looks like about 20 reports so far. If you have a leak or had a seal replaced, please report. Thank You.

 

[Herbpov]

Can you file these with NSTHA? (however you call it) If so we ought to keep track of these like the rear ends it seems the read ends and axle seals are a major flaw for the Titan

Yes, please do. www.nhtsa.dot.gov

Hey, I noticed they have a TSB on it. Something about a breather? Does the TSB mean anything to us? I have take mine in 2 times. No mods to the back in of my truck. The last time I took it to another dealer and they were trying to tell me I had to take it back to the one that did the original work. After I pretty much told them no they looked at it and said there was no leak despite the diff. being wet looking around the bolts. The said they understood what I was talking about though. They didn't fix my leaking rear windows either!

That TSB has to do with removing the breather from the old axle and installing it on the replacement unit.
