So I installed a set of Yukon 4.88s with ARB lockers front and rear about 1000 miles ago on my 2010 Sport. (yea I know, don't waste money on the 30....) The install went well, broke the gears in per Yukons instructions. After the break in, took it out for some light wheeling to test the lockers. Worked perfectly as it should. Now about 1-2 weeks after that I have a leaking front AND rear pinion seal. Of course all this was new with the install kit. The front is a much worse leak as it will actually leave about a half dollar size spot on the garage floor and the rear you can tell is just seaping out. Any thoughts on why both would leaking after doing ok to start? The axle vents are clear and no other issues that I can see.
