What type of diff have I got?

[Mos]

A - 2 сателлита
B - 4 сателлита
C - 2 сателлита с LSD
D - 4 сателлита с LSD

Hmm This is off an IS200 forum:

A01A - 3.916 ratio Open Centre
A01B - 3.916 ratio Torsen LSD
A02A - 4.083 ratio Open Centre
A02B - 4.083 ratio Torsen LSD

Which doesn't correlate with the russian info, but does somewhat correlate with the 2,3,4,5...

Edwagon - if the IS200 ones are anything to go by (and it works that way), it would be 3.916.

Cheers edwagon. Every time I hear that a D = LSD, it just confirms it for me.

Mos - Are you sure the IS200s don't just use the old system? ie only As or Bs, no Cs or Ds?

[edwagon]

Cheers Mos, the Is200 codes seem to work the same as the Soarer codes then. I thought I had them sussed until I opened up the A02D chaser and found a 3.7. I have a feeling that the jza80 Supras have a different set of ratios to Soarers too (4.1 is the same, but AFAIK they have a 3.7 instead of 3.9). When I crack open the Aristo A01A I'll add it to the list in case anyone else comes across one.

When I ordered my A02D and had i sent up from a wrecker down the line, I was sweating a bit beause its hard to find reliable info and I was scared Id just paid big bucks for a filthy single spinner, but sure enough it was the mighty torsen. Someone suggested that maybe D = Drift, so I guess it figures!

so is there a accurate / current toyota axel identification database around?

Not sure what you mean there?

My understanding was: 2,3,4,5 - old system, A,B,C,D - new system. (Note that this is the last character of the code, and not the first).

If you're saying it's: A,B - old system, C,D - new system, I have no idea what you're talking about

I guess I've got it wrong in my head then. I'm most certainly not an expert on axle codes

I assumed there must have been 3 systems -
2, 3, 4, 5 - oldest
then A and B only
then A, B, C and D - newest

The reason I thought they must have redone the letter system was because on Supras and IS200s (as you posted above), you can only get A or B - and a B meant LSD. Since there are no Cs or Ds available on them and that Russian site shows A, B, C and D (with different meanings for the A and B codes), I just assumed it must have been a new system.

Not that I know of, but I'd love it if we had one.

On the my.is site (US IS300 site) they mention C and D but nothing hugely structured and sometimes inconsistent.
