Just picked up a Taco rear axle for my project to replace an 8" that's in there now and too narrow.
The studs are the same pattern, but 2mm bigger and about 1/4" larger diameter pattern. So putting in my current 3rd is out.

So now I'm 3rd shopping and wondered if the 4 cylinder stuff is less desirable then the 6 cylinder stuff for these like it is for the older 8" stuff. I've found some 4.56 3rd's from a 4 cylinder and having the correct gear is a huge plus.

I understand that there isn't a Detroit for these, but how is the No-Slip? I prefer a mechanical locker in the rear (have ARB front), but I've trashed a No-Slip once before (granted it was in a Dana 30).

If there's a FAQ or something out there with this kind of info a link would be great. :D

the non-trd axles (referred to as the 8.4) should be the same regardless if they are from a 4 cylinder or v6 model, but yes you are correct about the lockers, the only one i know of that replaces the carrier will be the ARB, there was some talk a while back about someone making a full spool for them, however i dont know if that was ever done or not, nor can i remember the company thinking about making them.

So there won't be an issue with source the 4.56 geared 4 cylinder 3rd? Sweet :D

How is the TRD rear different? Bolt pattern on the 3rd? Width?

the trd e-locked rear uses a standard 8" ring (and pinion i think) but the 3rd is not round. it has a rectangular cut in the top left that juts out for the locker mechanism.

Okay, driveshaft compatibility check time. Does this thing use the same flange as the 8" or am I having to redo the driveshaft?

i think if you were to have any problems they could be solved by drilling another set of holes in the mounting flange but i could be wrong. i don't own a tacoma but if i were to guess i would say that all Taco rears use the same driveshaft mounting flange to keep production costs down. why spend extra money money developing a diffirent mounting flange just for TRD models? just a logical conclusion.
