My truck is an 04. I have the big tow and the off road package. It does not have the LSD rearend. It has an electronicly locking diferential. At about 7000 miles the rearend sounded great. Read all the problems and decided to change the rearend fluid to the synthetic. The fluid that came out was silver in color. Big chunks of the spider gears came out also. Took it back and they installed a 05 rearend. If you have an 04 truck I would highly suggest putting in 70W140 synthetic fluid. This is what the factory is puttin in the 05's. It will take just over two bottles of fluid. Hope this helps.

If you look at the back of the differential cover, there is a threaded plug in the cover. Screw it out. If there is any fluid coming out then there is plenty. If none comes out then stick your finger or something that has an angle in and point it down. If the fluid is just under (<1/8" or so) then you are OK. If greater then you will need to add the correct fluid.

Have problem with my rear diff!!! Took on trip up to Maine with snowmobile trailer, 2 sleds in it. Has diff lock light start flashing then come on solid. Got to my camp with no problems but light. Drove home had no light until 20 minutes from house (4 hours driving no trailer) Dropped truck @ dealer 3/21/05...diagnosed as shorted switch....picked up truck while waitng for part....couldn't drive, rear end kept locking up and skipped through turns. New rear end ordered...waiting until 4/29/05 release date to come and see if Nissan ships rear end. Love my truck ... hate the way Nissan doesn't care about the consumer that already owns a Titan. maybe the lawyer in Lemon Law will get them to move. Hear in Mass 15 days down = lemon.

All I want is a truck that I'm paying for. Anyone else out there / bad diff. Good Luck
