Brake Fluid Leak problems of the 2006 Nissan Titan

Rear end axle seals are leaking, after looking into this and several hours I found I could be caused from the axle vent not working properly, this causes the rear seals to be pushed out and fluid to leak onto the brakes, seems to be a huge problem and safety concern, I was pulling a small trailer at the time and nearly avoided a car that pulled out in front of me.

I own a 2006 Nissan Titan with 47000 miles. Partial VIN "1n6ba07a0" while taking it to the local midas shop for an oil change. The mechanic pointed out a leak on left rear axle seal. They quoted me with $350. 00 to replace the seal. However they also suggested to have the dealership attempt to replace under a recall/ warranty. . . The dealership quoted $1900. 00 to replace the whole rear axle under the guidance from their technicians and it being over the manufactures warranty and/or no recall. This sounds like a ripoff. Here is a quote I found on the club Titan forum site. . Read more...

I bought this Titan at tri-state Nissan in winchester, va. My brake rotor were completely rusted due to bad metal used - I had to replace them at 30,000 miles. My left rear wheel seal was defective and started started leaking fluid at 70,000. Had to replace even though I had extended warranty. Catalytic manifolds went bad and they knew it when it was under warranty - but they didn't replace them. Paint problem when the truck is cold - big giant spots in the clear coat. The manifolds manifolds need to be recalled because the exhaust is entering the vehicle.

Noticed a small grinding noise underneath my 2006 Nissan Titan le. A friend tells to check the bearings. I bring it the dealer, dealer tells me I need to replace the rear bearings and seals - $900. 00. They also tell me my brakes and emergency brakes shoes are shot due to bearing fluid leaking all over them, they wanted $1600. 00. Replaced all the brakes myself, which were totally fine. . . . I then notice the same grinding noise plus another under my drivers side floor. Bring it back to dealer asking them why. I come to find out the front differential is shot along with the transfer case. This truck has highway miles, only driven in 4x4 for snow. How can this happen? I then proceed to look for answers on the internet and find out that there are many other Titan owners with the same problems. Nissan has actually changed the part numbers for the axle due to the issues that are related. The new repairs will cost between $3600-$4000 which I cannot afford at the moment. Drive safe Titan owners. . .

Left rear axle seal failed at 29,900 miles (1. 5 years ago) and entire rear end/axle assembly was replaced by Nissan dealership. Now have driven 48,000 and the replacement axle seal on the left side (same as before) has started leaking and must be replaced. There have been no suspension modifications to this vehicle and it has never been used for towing or any type. Rear differential leaks and can cause failure of rear end and possible accident from sudden stop caused by axle locking up. Rear differential fluid also leaks on real brake rotors and emergency brakes and could cause brake failure. Several similar incidents of this same failure can be found online and it appears to be a significant safety issue with this vehicle (2006 Nissan Titan).
