One problem related to axle shaft has been reported for the 2006 Nissan Titan. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2006 Nissan Titan based on all problems reported for the 2006 Titan.
My 2006 Nissan Titan has an axel seal failure on the drivers side rear, differential fluid is leaking onto the rear brakes causing reduced braking and also the potential for axle/differential failure. Nissan refuses to address this design flaw. They have a re-engineered replacement axle shaft and seal at a cost of about $800 per side. This should be a recall not $1600 out of my pocket to fix. Will Nissan and ntsb wait until there are fatalities before they address this common issue with the Nissan Titans?.
