Is there a thread that explains what is all involved in adding a locker to a non locker model? I just picked up a 99 that I'm going let my youngest drive for a while to help her get thru ultrasound school. Long term I would like to use it as a wheeler for myself. It's a SR5, 4X4 automatic with the 3.4 V6. Doing a search it looks like the locker is a 8.4" compared to a 8" for the non locker. Which makes sense since the owner's manual shows it requiring more oil even though there is more stuff inside. Also looks like it will have 4.30 gears instead of 4.10 gears.
Questions
Does the rear locker require a separate ECU or a different main ECU? Will the current wiring harness have the plugs to add a locker? I think it should have a plug for the switch, dash light, rear axle and possibly ECU. I can see on the dash where the locker light should be. Locker switch location has Toyota security plug there now. Which is the easiest way to get around the gearing. Switch gearing in the rear axle or just switch out the front diff. It has the ADD which is working find. Guessing getting the complete rear axle is the way to go. Figure a Tacoma might be a different width and require mods to work on a 4Runner. Since I have time to gather parts looking for the easiest way to convert.
Thanks for any help.
