I really need help soon on this subject.I need to put at least a 4.10 gear in the rear of my 97 V6 2wd tacoma .But I want to keep it simple.I see alot of people selling thier 4x4 rear diffs set up with 4.10 or 4.11 gears.But will a same year model 4x4 rear fit my 2wd rear?

jimbo74

are you talking about the 3rd member only? or what? if they are bot hte 8" rear end, then yes they will fit... however, i dont know much about the tacos, and i think that they will not fit due to hearing something about the non trd tacos having like an 8.4" rear end.... not 100% sure on this

They are both 8" non TRD rear end but I have heard the same thing about it .

Non-TRD Taco's (2wd and 4wd) with a V6 should both use the same diff as the Tundra and T100. The so-called 8.4" diff that is really 8".
So yes, a '97 4x4 Taco rear diff should fit a '97 Taco V6 2wd rear.

I believe the 2wd 4cyl is different though.

Thank you soo much for this information.

Do you have the 2wd "work" truck or the 2WD Prerunner. They are different and have different 3rd's and different axles all together.

The "work" trucks have 7.5" rears. While the PreRunners could have 8" or 8.5" depending on what options you have.

My 2wd is a V6 powered Tacoma EXT cab .NON TRD.I know for a fact that the rear is 8" but other than that I nothing else about 3rd members or anything about rear diff or gear.Im still kind of new to the offroad world.

Is it a PreRunner jacked up or a "work" style mini-pu?

ErikB

AFAIK, only the 2wd Taco's w/ the 2.4L engine have the 7.5" diff and the rest have the Tundra style diff.

Here's the easy way to check- are the bolts holding the 3rd member to the axle housing 14mm nuts with 10mm studs or 12mm nuts on 8mm studs?
14mm nuts = Tundra style diff.

Also, the diff "covers" look different since the Tundra style diff has the big bearing cap braces. Tundra style on the left, older 8" style on the right:

You need to answer the question regarding what model you have. Do you have a 2wd regular style which is a 5 lug or do you have a 2wd Prerunner which is a 6 lug.

If you have a Prerunner, then you can swap in any complete 4x4 Tacoma Rear (they are all 6 lug). If you just want the 3rd member, then you need the "8.4" 3rd (non e-locker).

If you want the e-locker rear, you can wire the locker or get a cable to engage it. You can find a complete e-locker rear for around $700.

The truck is a non prerunner V6 EXT cab.It has the 5 lug pattern.I need to know what type of rear 3rd member I have before I try to get gears for it.I do already have the ARB locker for it and Drivetrainsuper stores calls it the V6 or Turbo 8" rear.But what size?
