Easy question for 2WD rear Diff experts please!

Need a definite answer. I own an '08 double cab TRD Sport package with 2WD and auto tranny (do I have an 8.4 diff?)....

***Can I use a 4:10 gear that came out of a 1st gen 4x4, V6 Tacoma 5 Speed???? Came with the 4.10's out of an 8.4 Diff (NON E-Locker)

Definitely "YES", or definitely "NO"???

Also, does it matter that this gear came from a 4x4 truck?....other than I only need the ring and pinion for my 2WD rear diff only?


Thank you!

 

Nobody in tech chat has any firm idea?

 

Thanks for the link, ill be reading through that tonight!

I think there's an "install kit" that needs to be purchased also in order to complete just a ring and pinion swap?
My plan is to simply drop off the truck at a local reputable axle shop and hand them the ring and pinion and say call me when you're done (not doing this myself).

 

Is that a "kit" I could also get from the dealership? My guess would be that the dealer sells all the pieces seperately. Either way, I wonder if the parts are better to get from Toyota vs aftermarket brand.

 

why not just swap 3rd members?

 

Because I know a guy who's selling only a ring and pinion (already removed from its original vehicle).
