I don't know about a street car but on a dirt car every time I've ran a non floater axle I've had to install something in the axle tube near the center section. Any company that sells to dirt track racers sell the seals I'm talking about.

I had Moser c-clip axles in my 8.5. I sent them back. It cost me $50 to try them out!

They leaked on both sides, but more on the right than the left. I changed brand of seals...no change. I put it to the fact that the seal surface was not polished like the OEM axles. Moser disagreed. I had them measured at a machine shop and they were slightly smaller than the OEM axles I took out. Why did it leak more on one side than the other? Because of the turnings. On the right side, the turnings drew the oil out past the seal, like a screw pump.

I was told the leaks were because my vent was clogged, but the vent was clear. I bought axles from Tom's Differentials. They were not polished, but were cut finer and did not leak.

Your mileage may vary.

I had the same problem with my quick performance rear. The axle bearings have a crappy plastic seal. I took my axles out after only 60-70 passes on them and had new seals / bearings pressed on = problem solved!

IS it leaking from the inner or outer seal. We see a lot of cut o-rings on the 9".
If the inner seal (bearing) the only way to fix is to purchase a new set of 9" bearings and press the old ones off and press the new one on.
Also make sure you housing has an OPEN vent. A plugged vent of capped vent will push oil out.

i looks to be coming from the inner seal closest to the axle itself i do not think it is the o-ring seal to axle tube part .

One way to fix it (if the vent is not plugged) replace the bearings.

Several on the MonteCarolSS site have had this same problem. Bearing seals are crap.
