[:@] Hello
I have a 1999 Mazda B4000 and today I went to put my truck in 4 wheel drive and noticed that the front tires are not lockin in.I can feel the power difference as I believe the transfer case is working fine.I have the auto hubs could these be worn out or could it be a vacume or electical problem?If anyone can help me that would be great. It figures that on the first snow of the year here in PA my truck has 4x4 problems.
Thanks Brian

 

i have the same problem with my 95 b3000. did you ever figure out the problem. Please let me know.

 

i think it is vacume line checklines from vacum actuator

 

if they are aything like the full size fords they are a pain in the butt and almost always a vacume line. if the seal in the hub goes out it wont work on either side and the seal isnt a do it your self job mostly dealer only type
