Axle swap and tone ring?
and if there is a thread somewhere about a guy machining a tone ring down for a jk and it fits on a dana 60 stub shaft.
Speedo is fine, I need the ABS to work instead of splicing the rear wires and to register as a DDOnce you put a 60 in a WJ isn't ABS fairly a mute point? Its not like it affects functionality of the vehicle like in a JK. Speedo is run from rear diff. Just pull the bulb for the light and move on.
