I recently replaced my rear seal on my transfer case of my 88 YJ. Now for what ever reason, I have fluid (Red - so I assume its from the transfer case) leaking from my U-joint just behind the Transfer case after the jeep sits after about a day. Not much, but usually about a spoonfull is on the ground after about a day of sitting. I just can't see how fluid can be leaking from the U-Joint. Am I missing something?
