My 4hi and 4low are not working

When I turn the switch I hear the normal sound locking in of 4wheel and when I put it in neutral and switch to low I hear the louder one

But the front still will not pull at all

f150corey

Yea the lights come on and I here it kinda "clunk" its going in to the shop monday because I cant figure it out. Ill let you no what they say it is

f150corey

hey i just got a call from the shop. they said my truck will be ready tomorrow and that the problem was that my left front hub assembly is bad, not holding a vaccume. oh and that my ball joints were bad. but that has nothing to do with the 4x4. ooh and because i bough the truck 5 months ago and only put 7k on it there fixing it for free !!!! i dont have the extended plan. because i has a plow.

was the cv axle broke

I'm messing with mine now and the front drive shaft is spinning but not the front wheels

I think it could be the vacuum line but not shore where it is

f150corey

not that i no of. i didnt ask to many questions on what they did because it was free. but all i no is the left hub wasnt holding vaccume. ill get my paperwork tomorrow and let you no what they actuily replaced.

i can almost guarentee that it is the vaccuum line that go from the solenoids to the hubs check near the battery around where the starter solenoid is they tend to go bad or have cracks from age. If there bad there is an updated version
