Question
How to replace front wheel bearing on 4 wheel drive

Answer
Joe,
As each vehicle has different specs for torque settings and methods of installation/replacement, I can't answer this without referring to a manual.  I would suggest that you purchase a repair manual for your Mazda at the local auto parts store.  They cost around $20 and are a great reference whether you are replacing a part, trouble shooting, or just want to check on how something works.  They have step by step instructions, torque settings, special tools are listed if needed, along with a trouble shooting section.
