Auto Parts: GM 4wd front differential swap, rear axle ratio, blazer s10

Question
Is it possible to use a Blazer GU6 front differential as a replacement in a 1992 Olds Bravada? I am having a hard time locating a Bravada differential, but S10 Blazer are easy to find. Can you interchange them or modify the Blazer to work in the Bravada?  Thanks I appreciate your help!

Answer
Hi Rob,

Depends on what years you're working with.

Here is the interchange for the '92 Bravada front axle:

4341711A
BLAZER S10/JIMMY S15 95 AWD, 3.42 ratio (opt GU6)
BLAZER S10/JIMMY S15 96 w/o "ZR2" opt; AWD (opt F46), 3.42 ratio (opt GU6)
BRAVADA 91-94 3.42 ratio (opt GU6)
BRAVADA 96 3.42 ratio (opt GU6)
************************************
Always match front & rear axle ratio.

Looking for a reputable service technician? My advice on finding a good technician is: Steer clear of the dealership and 'chain' stores like Firestone, Sears, Pep Boys, Monro Muffler/Brake, Midas, etc. as they usually only employ ONE ASE Certified Tech just so they can say they do and chances are, that guy is the asst. manager or manager and is not in the store to diagnose/repair vehicles anyway. Find a service location in the link below or get some names out of the yellow-pages and do a drive-by. Garages that employ ASE Certified Technicians will be marked with the 'Blue-Seal' insignia. If unsure about whether a place employs Certified Techs, just ask to see their credentials. ALL ASE Certified Technicians will be PROUD to show and display their certificate(s).

Thanks for the question, I hope this information was helpful to you.
