Hi all.

Can any 1 advice me what Type (name and model number) of transfer case on my 2009 Hummer H3 3.7.
Also where can I get replacement parts for the transfer case ?
Thank you.

Mike

 

Both are Borg-Warner. The NR4 is for the None Adventure/Offroad. GM Parts House has them listed.

NR4 - B/W 4493 2.64 ratio.
NR6 - B/W 4494 4.01 ratio.

 

Hi mate.
Thks for your help.
What do you meant by non off road ?
So which model I transfer case below to ?
Thank you

 

If you have factory locking differentials you have the NR6. If you do not, you have the NR4. On your 4X4 control panel lockers are indicated on a button represenative of 4 wheels with an X on axle that locks. 06-08 will only have 1 locker button 09 and 10's will have 2. The none Adventure/Offroad pkgs. will not have a locker button. I suggest you do some futher research on this forum to find out what you have and what it is used for before you go tearing into things. I hope this helps.

 

Yours is the NR6, it will have one of these ID Numbers

GM opt NR6.

 

Thks Smith. Your are the man. I nearly order the wrong replacement parts.
Yes. My car are fitted with the original diff lock and indeed there are 2 diff lock.
So for NR6 is there a place online I can get spares or any website I can look for upgrades of internal parts.

 

So your's is an 09 or 10 if it has front and rear factory differential locks. Replacement parts you can get at GM Parts House. I have no experience with upgrades so someone else will have to help you with that one.
