| Description of the problem | Failure of rear differential. 2004 titan purchased 8/04. In 8/05 while in washington state on vacation, noticed 3-4 mpg drop in gas mileage. Crawled under truck looking for gas leak and found differential fluid had shot out of front seal and fluid was low. Added fluid per owners manual and brought to a dealer. Dealer said i used wrong fluid and should have used synthetic. At this point nissan realized they had a heat problem and switched to synthetic and installed finned differential covers (which i noticed were on the 2005 models in their lot). I told the dealer they were covering up a heat problem on the 2004 model and wanted an inspection. They refused since they didn't see a problem. Installed mag-hytech cover myself. Periodically had oil shoot out of vent on axle tube and all over tire. Dealer said that was normal. 4/17/08 at 41000 miles right axle seal failure, dealer fixed. 10/13/09 at 52589 miles left axle seal failure, convinced nissan corporate to fix and they did. Found fix on-line for bad axle vent design, added vent hose and filter but still had fluid coming out. 3/8/10 at 55900 lots of metal on dipstick, changed fluid and pieces of spider gear came out with fluid. 3/16/10 at 55919 brought to dealer for inspection hoping to get nissan to repair differential. Nissan refused since "too expensive and there wasn't a recall anyway", one of the dumber comments i've ever heard. 3/22/10 at 55924 had 4x4 shop repair differential. Shop showed me nissan had installed wrong bolts in differential. Shoulder on bolts was too short and only hit one side of spider gear assembly flange, with other side riding on the threads. Bolts eventually backed out causing spider gears to self-destruct. Cost me $2100 to repair, existing ring and pinion were in good shape inspite of issues. Replaced differential assy with detroit true trac. Shop used bolts from another dana differential and cut length to fit. |
