Ok i recently purchased front and rear truetracs, i am about to install them with the help of a mechanic buddy and looking on the diffs for a part number i see 912A693 on one and 912A694 on the other. I can't seem to find these part numbers online to figure out which one is front or rear! Hopefully i got the right ones shipped! The only other numbers i see are TT70P10284 23m11 and TT70P1028 24k11. They are being installed into an 01 D2 SE7. Anyone have the answer?

 

Why is there a front and rear? I would imagine the diffs would be the same.

Either way, here are the part numbers:
Front: TT 912A407
Rear: TT 912A383

 

In a truetrac the gears spin opposite directions for front and rear.

Interesting, but what about driving in reverse?

 

When you install the T.T.'s, make sure to only use convential 85/140 oil, no synthetic because it will slow down the T.T. reaction time. Also, make when wheeling that you are always locked up and be very careful to run all 4 tires at the same pressure, I speak from experience with them, love them but you do need to learn a few tricks to get the most out of them.

 

I think they will still work backwards, but maybe not as well. I don't think ashcroft has two different parts for their version, since their version supposedly works a little better anyway, with twice as many gears.

 

Hi did you ever solve this problem? I have the same problem I have the 912a694 and need to know whether its a front or rear

 

You can tell front from rear by looking at it:

If not the right one you can change it.

 

Mine is built into the diff casing was just trying to identify it by that number to save stripping it down

 

912A694 is the front

912A693 is the rear
