1) How many miles? +25,000 miles
2)How much weight do you tow? ~2,000 lbs. & ~5,500 lbs.
3)What % of the total mileage is towing? (Best guess) 3%
4)B/T, O/R, or none 4x4, BT, and OR
5)E-lock yes or no Yes, May '04, (the very first month of the E-LOCK's introduction).
6)04,05, or06? '04
7)Did you change your diff fluid if so at what mileage, and to what brand, and viscosity? Yes, checked F/R at 2K miles - full and "looked good"; changed around 4K not bad looking fluid, an 1/8 " of metal debris on magnet; 12K very little debris on magnet 1/32" to 1/16" of debris; and 23K very slight debris, 1/128".
Here is the best stuff on the market. Too bad Nissan didn't choose this instead of the full synthetic crap they have all of the '05 and '06 Titans using:

Check out the fourth pic down. It pretty much shows why the '05 still go out, (well 2 or 3 of them I think

). The egg beater test says it all:

8)As best you can explain the way you truck was treated and be honest if at all possible. gentile,normal, or drive like you stole it. this is very important question to me as it may or may not rule out driver abuse.
I followed all break-in procedures, towing included, and things like E-LOCK not over 12 mph. 4-LO under 30 mph, and 4-HI 60 mph or less. I don't abuse it, but I paid for an Off-Road pkg. so I will off-road it, and a Big Tow package rated to around 9,000 pounds with my setup, so I will do it and not worry.
I do off-road climbing steep arsed jeep trails, river rock courses etc. and generally don't baby it. But it is basically in mint condition. Never have power-braked, but I think a truck should be able to take it, since the market is full of guys that do.
The worst abuse this truck ever gets is on a public road of my commute. It has some large roller-coaster like dips 10-12 feet deep, and the Titan comes very close to getting air on these, (while driving the legal rate of speed of course).
I plan to keep this truck forever, and I'll be very surprised if the differential ever goes out. I think a few bad parts have made it into the channel. If I am wrong, the five year 60,000 mile power-train warranty eases any paranoia, (and my 100K extended warranty helps too).
Worst thing is the poor customer service of Nissan Corporation. If their product breaks, they need to provide 4x4 owners with a 4x4 truck to use, big-tow owners with a tow-capable truck. Being cheap arses and providing malibu's and corolla's will not make me be a return Nissan customer. They need to have the parts, (rear axles if they choose), available at all of the dealers so the customer is not inconvenienced, even if you blame them. Nissan Corporation has turned some of these guys into martyrs with their bad customer service. I even feel sorry for members like FishHead even though some seem to think he/she is a troll.
