Axle Differential Codes and Ratios up to 2004

[Deerhurst]

HF35 merely means it is an open diff with a 3.5:1 ratio.



Being a 96 I'd think you have either a C200 or a H233b.

HF denotes that the axle is a H190 axle, 35 denotes the gear ratio.

with that being said, if you have a diff cover then you have a C200 axle. most likely swapped out by a previous owner.

Looks like I do have the C200 based on my manuals and the diff back cover plate. I wondered about the code because I bought it off my dad (orig. owner) so I'm sure it's the original diff. Thanks for the info.
