My2000 ford excursion wont completely disengage out of 4 wheel drive

swithc it to 2wd drive and put it in reverse,it might come out of 4wd that way

I have a 1993 ford F150 and when i bought it the 4 wheel drive did not work. Now it tries to engage while driving and makes the truck buck. How would i disengage it so it wont work period?

Something worth trying. Many vehicles can be dis-engaged from 4 wheel drive by putting the vehicle in reverse and backing up 35 to 40 feet.

When you take the vehicle out of 4X4, you should always back up for around 50 feet to fully disengage the 4 wheel drive..........Hope this helps and also the electronics on the transfer case may be corroded or bad.

It sounds like a problem with the drive shaft knuckle its a sealer unit and not serviceable See if when you turn the axle back and forth you hear or feel clunking noise or feel movement in the sealed joint Iwould check the conduition of wheel bearings this kind of a problem tends to create a lot of heat so a over hall of bolth front wheels mabey brakes and bearings is likely along with any axle problems you find It sounds like you waited to long to address this things like don't braek over night they give waring signs make noises viberate you need to look and listen. repairs tend to be much cheaper and easyer if you do. It still sounds like you can save it but you need to do everything that it needs good luck and sorry its not easy fix but it needs work

Be sure to put the truck in neutral, while engine is running, while you disengage from 4 wheel drive (low) to 4 wheel drive (high) and then finally to 2 wheel drive. It is critical to shift transmission into neutral when switching out of 4WD Low, as indicated in your owner's manual. Hopefully, this will help to FixYa problem!

Return to the shop that just relaced the joints

my4x4 is stuck and can't change back to 2w drive

This is common. the locks due tend to freeze up and need either a greasing or replacement. I do suggest automatic locking hubs that you don't have to turn yourself. You can get the part almost anywhere

Once you turn off four wheel drive back truck up at least 20 feet. This should disengage.
