Hello all. I have a 9" built by Quick Performance (I called them about my problem, thay were no help) and it is leaking from the diff vent tube. I have a 4' tube clamped to the vent. The tube wraps around the axel tube, is secured to the top of the chunk, then continues down the other axel tube and ends on the floorboard (picture a tube wrapped around the diff 2 times with its end secured to the bottom of the floor pan with a clamp). I put 2.25 quarts of fluid in the differential (per instructions). Differential fluid spews out of this tube every time I drive, I bet I have lost over 1/2 quart as of now. Fluid is all over the back bottom of the car.. the gas tank... etc... Should I be worried? I kinda am. It is a nodular case with a Eaton True Trac 3.80 ratio. How much fluid do these things take, did I just simply overfill it with 2.25 quarts? Will it drain itself of all oil? WTF?
