HOW TO TRANSFER FROM 2 WHEEL DRIVE TO 4 WHEEL DRIVE 1985 CHEVY K10 AUTOMATIC TRNSMISSION

SOURCE: 1999 Chevy 4x4 engaging

Check the solenoid at the front axel. This is a rather common prob. First check that power is at the axel, got power, clean and put it back. Please do not even look at the tranfer case! At worst you may need to replace the axel solenoid! Frankster016

hey there i cant tell you what you are missing but i can tell you how to disengage the front wheels . ok you have a vacum line that runs right under the battery and a line that comes up from the front diff. to the same place ( you may have to remove batt and batt tray to get full access to this) un bolt it and temporaly put batt and batt tray back in start it up and decompress this and see if it comes out .... you should here clunking noise if it goes back in ... if thats the case just pull that big vaccum line off .... to test get all four tires off the ground and have some one put it in drive but dont hit the gas it should turn on its own ...if that dont work check the cable that runs down to the differental

It's most likely the "four wheel drive actuator" This is located on the front differential housing. It's cylindrical shaped and has a large hex (about
1-1/4") and two wires coming out of it. Usually they short out and blow the fuse but, I've also seen where they just quit working and sometimes they just get slow to work. The "actuator" has a heating element in it and it warms up, some sort gas, causing it to expand thus engaging the front wheels. In cold weather it may take a minute or so for it to engage, so put in four wheel drive and wait for a bit and see what happens.
