4x4 issue please help!!!
 

i went to put my truck in 4x4 to pull my boat outta the water and it would not go in. it is a floor shifter. i pulled it and it feels like it goes in but the axle dosent actuate. same in 4 low. is it the actuator? im thinkin that or vac leak? any ideas? thanks in advance guys.:c:

Check your vac lines all the way to your axle and if your getting vac then yes it is your actuator get rid of that and get posi lock cable and put in tons better and dont have to worry about it failing

good advice! thanks blackcloud! didnt even think of the posi lock cable!:c:

if you think its a vac problem does you a/c blow only out the defrost

mine does, how do i fix this ?

yes it only blows out of the defrost!!! and the breaks suck lately to!?

looks like i am hunting for a vacume leak... any popular places to start my search? my brakes have been messed up to... seems like it may b the pump?:argh:

also the steering gear box just started leaking to... could that have somthing to do with it?

I would say yes you have a vacum leak and no it has nothing to do with the steering box leaking. Just start at the vacum pump and check all the hoses, I'd bet it's the big hose that goes to the brake booster because I had a broken vac line on my cruise control and it didn't affect my brakes or anything else. :c:

i checked the big line going to the booster.... it was swollen so i replaced but it didnt make a diff. so i will continue my search 2maro.

check the line on the axle for the CAD

If the hose was swoolen it's probably from oil getting in it and that may possibly be from the vacum pump being bad :c:
