Customer: replied 1 year ago.

yes i do need help.but i cant stay to answer ?s xmass shopping.but please do help

Expert:  hilltop4527 replied 1 year ago.

I hear you on the christmas shopping, I have been doing plenty The way your vehicle works is that when you put it in 4x4 it sends electrical signal to a solenoid that has vaccum(suction) lines connected to it.One line has suction which is created any time the engine is running and the other should not have suction until you put it in 4x4 mode. when the vehicle is placed in 4x4 mode a valve inside the solenoid moves which allows vaccum(suction) on both lines.This other line is connected to the front hubs and it sucks a gear in place to cause it to lock the hubs into 4x4.What I need you to do is to try to locate this solenoid, it should be mounted under the hood on the left side(PASSENGER SIDE) of the engine. You will see a small black canister with a small black rubber hose going in and coming out of it. Follow this hose when it comes out of this canister it goes directly into the solenoid.The solenoid will also have two wires running to it. Let me know when you find this solenoid. This could be a cheap simple fix. I will step you through some simple diagnostics to see if this is something you can fix yourself and save you some money. I look forward to hearing from you soon.

i started truck and there is vacoom on one line none on other.i put in 4x4 and then i have vacuum on other line.so i guess so far so good.next step please

Expert:  hilltop4527 replied 1 year ago.
Ok the next step is to trace the vaccum line to the wheels and pull it off and see if you have vaccum there. I am not sure but you may be able to turn the wheels and reach these vaccum hoses without jacking it up and taking the wheels off. The hoses should just pull off you may have to get them twisting a little. if you have to jack it up be careful and use jack stands if you have them. Let me know what you find

hey boss i finaly gotten the hubs not to leak with smoke machine ( parts where not easy to get) i have vacuum but still no 4x4 what else should i look at. thank you

Expert:  hilltop4527 replied 1 year ago.
Do you feel it gear down when placed in 4 low?
Customer: replied 1 year ago.


i feel in go into gear when i put it in gear.and yes it took a few times but yes if i put into low gear i feel a change when moveing truck

Expert:  hilltop4527 replied 1 year ago.
I really don't know what else to check. If the transfer case is going into gear and the vaccum hubs are engaging I would suspect a broken cv axle but you should hear a loud thud while trying to pull out in 4x4 mode. You could also jack it up to see if the front axle is locking in. Maybe the vaccum isn't strong enough. Can you hook the vaccum hose going to the front axle to a strong engine vaccum some how and then test?
