2005-2016 Tacoma Axle Codes

My 07 has a C6 sticker next to the LSD sticker..Right on the rear of the differential...Double check but that means its a LSD w/ 4.300:1 gearing inside...Gotta go inside and check out that intense hum that is so ambient and hard to peg down...The pinion bearing has a clear grind with my stethescope...I am praying for no more damage past the crush sleeve...

 

I believe all 2nd Gen V6's have 3.73

 

You may be right Shaker..I am going to double check when I get on this...That C6 sticker may be for something else entirely...The inspection guys #...lol

 

A04C is the code thats in my doorjam..According to the LC Engineering site. The A, well,even they don't completely understand it but 2 types of gearing was offered that year. A and B..The 04 is showing that my gear ratio is 4.56..The C is " 2 pinion,LSD ? " with a explanation about older models...bla...AND I'm running Michelin Defender LTX 265/70R17...which depending on several other things, will alter the gearing as well.. Amazing that even though I believe what I'm seeing, LC still has me not convinced...The fact that I'm about to have a nice snifter of bourbon makes everything somehow, fade to the rear of my mind till tomorrow..lol

 

2016 OEM Gear Ratios:

 

My axle code is A02A 8" 4.10:1 open but I have the option to shut off lsd when I hold the traction control button in. Doesn't make sense to me.

 

You have electronic brake actuated simulated lsd, so it makes sense that you can shut it off.

 

So if I'm understanding this correctly I have a 8" open differential with 3.583:1 gears.
So I just need standard gear oil.

2005 SR5 V6 4x4 access cab

 

A = 8.0"/205mm

04 = 3.727:1

A = Open

 

IIRC all 2nd Gen V6's have 3.73's.

 

My 2014:

A04A

The entire line:
C/TR:040/FQ13 TM: A04A/A750F

 

According to the 2005 Tacoma Specifications guide: That is correct. I think these remained and applied to all 2nd gens
right through to 2015.

2.7l 5-speed manual (4x2): 3.307 PreRunner/4x4: 4.10
2.7l 4sp ECT auto (4x2): 3.583
4.0l 6-speed manual (4x2): 3.153 PreRunner/4x4: 3.727
4.0l 5-speed auto PreRunner/4x4: 3.727 (4.0l auto 4x2 not listed)

 

Anyone know the spline count on the 16 AT 8" non locking rear diff? Will the bolt pattern be the same across all Toyota Rear diffs? Trying to source an E locker

 

So my sticker shows A04C but I have a locker.

 

Well my rear end just went out, I've been looking online and everything I've been finding for 2012 TRD is 3,727, 8" pinion. I can't even find a 2012 Mexico mad TRD with the gears the other guy said he had. When it comes to your road dawg, doesn't hurt to triple check the facts sometimes! Gotta love this group!!!

 

Gears can be changed, what's the other guy say he has?

 

07 prerunner access cab.
A04C
I was about to buy a locker.
I do have a C6 lsd Oil only sticker on my diff.

So do I have lsd or locker?

I am looking for the perfect (for me) Tacoma, and I've run into an axle code dilemma that doesn't make sense. Regarding a dealer listing: "2015 Toyota Tacoma TRD Pro V6 Four Wheel Drive Automatic" the picture of the door jamb compliance code clearly shows a A04C/A750F. From the chart above that is a 3.72 Limited Slip, but the dealer still has the factory window sticker. you see below with "Elect Cntrl Lock Rear Differential" listed, and there is a RR DIFF LOCK button in the expected location on the dashboard.

Q: According to Jeff's chart, the code should be a A04B So, what gives here?

 

The long and short of it is that Toyota has applied extremely inconsistent axle codes to the Tacoma since 2010 or so. Some trucks missing the axle code altogether, others having different codes for the exact same axle, others having the same codes for different axles, even at the same plant.

It would be a 3.73:1 with E-Locker, forget the axle code.
