Leaky Rear Diff

Noticed my under 10k 2005 frontier has a small leak in the rear diff. Anyone else noticed this with theirs?

My neighbor has a titan and it's been in the shop a few times for rear diff leaks...

Avenger,

No leaks here so far after 6000 miles and 14 months. you are sure having your share of problems. What does the dealer say about all of this?

Truck, as i have named my frontier (i know, imaginative!), is a good truck the majority of the time... I am going to probably take it in next week (and get the king cab jumpseat TSB fixed too), but I have to get some quarts of redline just in case they want to drain the whole thing... I did a full synthetic swap to redline a while back but there is no way that should have anything to do with a leaky diff, and if my dealer tries to tell me otherwise he is going to be in for a fight

I might just use some cleaner and clean the whole diff, and then watch it closely each day to see where the leak restarts from... And check the diff oil level while I am at it.

I'll keep the site updated.

My 04 appeared to be leaking when it had 2000 miles on it.
So I decided to climb under and pop the plug and it was at the full mark.
So I wiped it down real good and looked at it it probably 10 times a day for at least a week and it never leaked again.

So im guessing it was slighlty overfilled at the factory and was coming out of the vent somehere.
Truck now has 31k with no diff leaks.

They had to replace my 04 rear diff gasket twice and retorqued the drain plug on another seperarte visit.

i cleaned it last night and watched it yesterday and today, still clean so far... im hoping with the temperature change the pressure may have risen and it needed to vent...

Forgive my ignorance, didn't you have to pull the diff cover off to change out the fluid?? Or is there a drain plug/filler hole arrangement?? (Sorry, too lazy to go out to the driveway and look under mine!) Could you have messed up the cover gasket when you put it back together??

No, its got a drain and fill plugs.....The only reason for one to take off the diff cover is to A. Switch it out with a Titan one....or B. Switch gears

Thanks for setting me straight. What is the purpose of switching to a Titan cover??

I believe the titan had a similar cover to what we have for the 2004 model year, however it was changed for 2005. If you notice, the Titan diff is positively tiny when compared to the F150/1500/RAM. So in certain conditions, say.....hauling 9500lbs up a 6% grade for 20 miles in 120 degree heat......it was over heating.
The new cover is larger, so it will fit another quart of liquid, and is finned. It is also aluminum.
Its got some nice heat sinking action going in the rear.....
Nissan was reporting a 10C drop in rear diff oil temperature, resulting in a over 40C drop in gear temperature.

Speaking of towing, I have to go get the boat....more on this later.

IIRC the Titan cover does not fit the Frontier's D44.

Stillen has a rear diff cover that increases the fluid capacity by almost a quart:

STILLEN BLK POWDER COATED DIFFERENTIAL COVER, 05-06 FRONTIER

but it's only for 2wd. Sorry.

And of course it's Stillen so it's NOT cheap.
