rear end help

how would i find out what kind of specs are in my rear diff, its 04 tacoma SR% non TRD 2.7 with a 5 speed 4X4, i know its a one tire fire right now, what the cheapest way to become a posi trac rear end

 

someone on here will know what size ring gear to get, i forget.

and for a rear locker theres alot of different options, you can do something like a detroit (always locked) lock rite (not always locked, clicks around corners if your not on the gas to save tires) arb ( push button air locker)

 

You have whats referred to as an 8.4" rear differential, even though the ring gear diameter is actually 8" .
Look on the sticker by the driver door pillar to see the axle code.
Yours might be B06A (3.91 gear ratio).

 

My code says BO7A what does that mean

 

Correct me if I'm wrong, but I think B07A mean you have a 8" rear with 4.30 gears and an open diff.

 

If you daily drive this vehicle I would recommend a truetrac for the rear end. I have one and its nice if you are 2wd and have to deal with snow.

 

How much are they. Are they easy to install

 

Non TRD is the "8.4" (still 8") diff.
You have 4.30's.

 

I'm fairly sure the 8.4" ring gear measures out to 8.18" actual
But it's always referred to, when ordering, as the 8.4"

The 8" would be the TRD axle (8")

^ both share the 7.5" front diff

* earlier Trucks and 4runners also came with a 8" diff (7.87")
tho' it cannot interchange with the Tacoma TRD axle

 

Yep, 4.30 gears, open
