Axle seal leak at HDPE track day

[crfblur]

So I just came from Barber and was black flagged for smoke from the rear. Gear oil is leaking out axle tubes with the passenger side being the worst. I have a 2013 Track Pack GT that has 50,000 miles. I have a Ford racing shock suspension Combo with P springs. Also, i did pull axles to install Gt500 brackets and rotors. I will acknowledge That I filled the diff with Mobil one gear oil. I was running Pirelli take off slicks at the track and was chasing down some German cars this morning with runs in the 1:48 to 1:49 range.

Please advise as I lost a Couple of sessions this week due to this problem. I'm guessing I need new axle seals, better oil, and a separator tank or even cooler.

I recommend amsoil synthetic extreme pressure gear oil it will withstand the rigors of the track. I would also recommend the JLT axle breather expansion tank, its easy to install and it works. As far as cooling a ford racing finned rear end cover should suffice.
