I am having a problem with a 95 blazer ... when you engauge the 4x4 the transfer case engauges and the drive shaft to the front spins but the wheels spin ... any idea what this could be ... differential? Hubs?

 

i have the same year and problem. a local garage said it was the front diff cable and or servo. they want 350 to fix it. i'm going to do it myself. the cable is 30.00 and the servo is 80.00, at the dealer. from what i found it's a dealer item. the cable mounts to the diff on the driver side and runs to the servo that is mounted under the battery. hope i could help. good luck,
joe

 

i have a 94 and i'm having some trouble with my 4 wheel drive too. some days it just won't work, but when it does click in everything seems to run smooth. i think its the transfer case...any other ideas?
