Ok, I am probably the only Titan owner in America this happening to. When the roads are slippery, my Titan will suddenly make a horrible bang noise. Totally random. It's like a run over something. You can feel it throughout the entire drive train. Only in winter on slippery roads. Otherwise this truck runs perfect. The dealers are worthless. I can't replicate unless under certain conditions. I would love to hear troubleshooting help. My buddy is 25 year mechanic who has been in my truck a number of times when this occurs and can't figure in out. Replaced rear diff with tru trac. Nothing. Replaced wheel sensors nothing. Is it in the tranny? Some special sense that can be replaced? Help Titan nation.
