You guys got me all worried that my diff is gonna fail, so I finally changed the oil on my '04 today (33,000 miles) and filled her back up with Royal Purple.

But this is what the magnetic drain looked like, so my question is:
Does this look like a normal amount of crud,
or an imminent diff failure? :crying:

Nope, normal particularly after 33,000 miles. Quit worrying.

Mine was changed at 50K and had just a bit more than that, so i think you are fine....
Good luck...

If I saw that I would have been worried too! I guess us 04's are still a little up in the air with our diff's. :eeeek:

For the sake of statistics, mine was a little low from the factory too. About 0.25in below the fill hole.

Did they fix the diff failure problem in the 05 model?
There have been diff failures in the 04-07 Titans. I have heard of no 08 failures. I have noted that most Titans have the build up on the magnettic drain plug but that has never been linked to failure. Most diffs start whinning at certain speeds and generally fail within a given amount of time or the owner takes it to Nissan when the noise is too loud to bear. Mine all started whinning and and one had leaky seals. I never waited for them to fail on me on a lonely dirt road. A friend of mine in Houston never heard the whinning but started hearing loud noises from the diff and had Nissan tow it in. They replaced the diff. His was a 07 with 2800 miles.

I changed the diff oil at 100k on my 04'. It was a little worse than yours, I believe its normal. Dont worry about it.

It's good to hear about diff's with that many miles on them. When mine went (05 quad cab, 4x4, off road) at 10k, I thought long and hard about getting rid of the truck.
Guess I'll stick it out and see what happens.

I like that color combo of the OP's truck!

I went back and blew up the picture of your plug and seen something I never noticed before. Are those big chunks of metal on the plug? Pretty much all the metal I see on my plug is a powder. Those looked like might be chunks. If it was chunks, I might take them to the dealer and show them. You could have bigger problems.

Looks like normal wear to me. Remember, I don't know of many who've actually had the rear ends "blow up". They were changed, most likely, because of a clunk sound or whining. Nissan replaced mine because when I changed the fluid, I found chunks of gears....although it had absolutely no other symptoms. So those who have had the rears just stop working altogether, or "blow up", are a very rare breed.

Those just look like small slivers. Aircraft engines and gearboxes are allowed to have slivers just like that so I think you will be OK.

Most of them were pretty small. What i would consider 'filings'.
There were 2 chunks in the mess nearly 1/2" long, almost like the coating had peeled off one of the teeth someplace. Trapezoidal profile.

No funny noises yet...:smoke:

Thanks Bigbang, I like the slightly military feel.

IMHO, you shouldn't have any 1/2" long chunks of anything in there.

So, I am in the process of gearing up the T for 10+hr drive up into the Adirondacks and I figure this would be a great time to take a look at those gears (in the rear) and see what's what.
And then I figure, hey, if I am already going to take the cover off, why not change it to one of the newfangled versions?

Then I checked the price...:crying:

Anyone know where I can get a PML cover for under $200?
Anybody have a finned cover they want to sell me for cheapy-cheapy?

If you're asking about the OEM finned covers, you can get them for $114 at CourtesyParts.

PML sells their's for $190 if you don't have it powder coated. It comes predrilled for a temp sensor if you want to add a diff temp gauge at some point. I recently got a Mag-Hytec for close to that price, so that's what I used. It holds more fluid than the PML. Both more than stock, though, so get whichever you want.
