Advertisement I've always wondered how much grinding it would take so when I got an experimental D30 that I wanted to remove a locker from I gave it a shot. This is how much grinding is required to remove the cross shaft from a LP TJ D30 with 3.73 gears. Despite what Randy's Ring and Pinion has to say about grinding them to clear the cross shaft I think this is a little too much. Maybe he was refering to other carriers and not the D30. I don't know of any others that require the ring gear be removed to get the cross shaft out. However this is what it took to get the shaft out. I chose this side because I only had to grind one tooth. The other side would have required grinding two teeth a near equal amount. Lower gear ratios might require more than one tooth. It sure would make trail swaps easier if a lunchbox locker gets trashed and spider gears need to be put back in. What do you think?
