So, I can't figure this out. I traded my stock irs to someone with a "beefed" up irs - Ford diff cover, MM Rear Race Grip Package (similar to what Full Tilt Boogie offers), G-Force axles, etc. And since I installed the new irs it has been leaking. There is some hard shaking/vibration from the rear end at high speeds, 120+, that I now believe to be the drive shaft ( I didn't get it balanced with the different irs) and needing to upgrade the front irs bolts to the 14mm ones.
I am not 100% sure if this is the cause of the shaking, but would the vibration from this cause the differential to expel the diff fluid from the vent tube?
