So im looking into putting an elocker into my 4 runner... and im not too sure what i will need... do i need to swap the entire housing? the full axle? or what not really worried about wiring just wondering what exactly i need to be looking for... new into wheeling scene. i have a 97 SR5... and do i only need to go with other 3rd gen runner parts or do the tacoma parts work as well for the elocker?
