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.

so, help me understand this, I have an 1987 4x4 5 speed pathfinder. I put a rear end from a 1995 4x4 pathfinder, didn't change the front diff. will this cause issues and bind the front if I activate the 4wd drive?

just so you know I have a 2003 crew cab XE V-6 Automatic I bought new in southern California
the door code for the rear axle is C46 its been an incredible truck and now resides on the Okanagan Valley in British Columbia.
We build a winery here and now i need to up-grade the Rear Axle to a posi due to snow and lots of horrible mud. I have goodyear duratrac tires which help but the right tire frier needs to go. i have been stuck to many times
i believe you mentioned that ARB makes a locker for this Axle. is that true?
is there any special notes i need to know to install that diff. I have been a auto tech for over 40 years so i should have no problem doing the up grade unless there is a tool i may not have ( I highly doubt it)
I am even playing with the idea of installing an LS1 from my vette when i install the LS3. i will definitely need a posi then.
