axle seals

2010 Pro-4X with 100k miles (new to me as of 2 months ago). Was driving along doing 35 and felt a sudden severe shudder from the right rear side of the truck. Pulled over immediately and smelled burning rubber on the right side so the tire must have skidded a bit. Tried to slowly drive forward...

I have a 2006 Titan with 58,000 miles, bought new. I planned to keep it a long time, but now having second thoughts due to problems: 56,000 miles - Both rear axle seals leaking -replaced under warranty. 58,000 miles - Transmission cooler line - replaced under warranty...
