I have a 97 with a high pinion 30 non disco, that i ordered a super 30 kit for with and ARB. I took everything out of the axle, then started to look at ARB's instructions for installing the locker. In ARB's instructions section 3.1 page 12 it says Insuring adequate Oil Drainage... My question is I would think that this does not apply to a Dana 30 axle because the oil is not actually in the tubes. Does anyone have any experience with this? I believe its due to the fact that the ARB moves the shims to the outside of the bearings instead of in between the bearings and the carrier, that makes it so on some axles the oil can not drain back into the pumpkin from the axle tubes. I appreciate any help, i couldnt find much about this.
