2007 Nissan Titan Crew Cab LE 4dr Crew Cab SB (5.6L 8cyl 5A)
exhaust dangerous problem
 If you are buying a 2007 Titan. Be SURE to go around to the right side of the truck where the tail pipe comes out under the fender, follow the tail pipe towards the muffler, INSPECT the first tail pipe clamp back from the muffler for security. This is the weekest part of the exhaust system, This clamp rusts and fails. When it does, the tail pipe will fall away leaving the muffler side tail pipe pointing directly straight up. If the truck is operated in this condition, the hot exhaust gasses will be directed onto the underside of the truck bed. The excess heat will melt and short out ALL wires going to tail lights ect of truck box.Since this review at 156000 miles the following has occured. Both front wheel bearings went out one at 160000 miles, and the other at163000, The rear end had to be totally rebuilt at 170000 cause the axle housing vent plugged and the wheel bearings and seals failed and metal particales from the bearing race contaninated the rear end oil and trashed the bearings at the pumpkin. and the left axle had to be replaced $2500 rebuild,  Transmission, #4 band failed at 170020 and the transmission had to be replaced with an overhauled transmission to the tune of $3900. am no longer happy with my Nissan Titan, This company has lost a customer!
