convert 1st gen rear diff to oem locking?

I have an 04 4x4 Tacoma but unfortunately it didn't come with the factory rear locker. I am interested in finding out how to convert my read diff to a locking diff - either with a factory locker or an aftermarket?

Can anyone suggest the easiest and of course cheapest way to accomplish this?

 

Swap an entire rear e-locker with matching ABS and gearing would be the easiest IMO. I am getting an ARB though, there is a group buy that will open in a couple weeks. The ARB is considered stronger by most.

Here is the group buy thread.http://www.tacomaworld.com/forum/group-buys/347994-arb-locker-group-buy-nov-2014-a-4.html

 

If your wanting to go with the factory elocker you will have to swap out the entire rearend. The 3rd members on the two axles are different in the way they bolt in. If you want aftermarket just search some 4x4 websites. I like eastcoastgearsupply.com. By the way you have the 8.4 Tacoma/ T-100 diff. Search away.

 

thanks everyone. I didn't realize i'd have to switch the entire rearend.

 

so if I go the arb route, I understand I need to add a compressor as well? if so, suggestions for the easiest way to do so? thanks again.
