Rear axle seal leaks in this model it is a known problem yet Nissan still chooses to do nothing about it ,it is a huge safety issue it leaks fluid continuously on to the back breaking system so not only could it comprise your whole back end but also your ability to stop your vehicle safely,this has been reported thousands of times to your agency in the meantime the consumers continue to replace these every 30-40,000 miles just to maintain their safety and others on the road when I feel it is time Nissan address this and take the necessary steps to ensure the braking system in these vehicles is not creating a potential hazard top the driver or others on the road . I took my vehicle in for an oil change yesterday only to find out my seal is leaking again and now my back brakes need to be replaced again because they are no longer safe due to the oil leaking on them again from this seal I drive my children in this vehicle daily to school to games and im thankful that I happened to need an oil change or I would have had no idea it was leaking again or just how unsafe my driving this vehicle could potentially be for my children and myself or anybody that is driving near me when it requires braking to stop .
Rear passenger side axle began to leak and fluid went onto brakes.
On my 2005 Nissan Titan, both of my rear axle seals failed with only 48,000 miles on the vehicle. The fluid leaks axle lubricant by the rear wheels, which gets onto the rear disk brakes, which makes the rear brakes ineffective, especially when pulling a trailer. Nissan replaced the seals, however the popular belief of the cause of this is a 1-way valve vent that allows the pressure within the axle to escape, but doesn't let air back into the axle. This occurrence causes a vacuum inside the axle, which pulls on the axle seals and causes them to age prematurely.
