Is your tyre's all the same size. Incorrect tyre's will change the racio from back to front and both driveshaft's are'nt turning at the same speed then it will grind. When trying to take it out of 4WD their will be preasure on the driveshaft's and this will leave if hard to disengage. Put it in 4WD drive it forward try the gearshift if it's hard to move then reverce a bit and try again it should come out easily. For all 4WD systems it is recumended thet the vehicle is reversed a few mitre's tto fully disengage the 4WD

SOURCE: cant turn hub nut on front wheel on 99 ford focus

If the car is jacked up you will need assistant to press the brakes, very hard and turn nut anticlockwise, it will be tight and you might need a long tubeular bar to go over your 1/2" master bar to loosen it, if you turn the steering out to the left slightly and get the bar horizontal, you can then stand on it, be carefull not to slip off or you WILL hurt yourself.

SOURCE: 2002 ford f150 four wheel drive front hubs not

Is the system ESOF ( Electronic Shift On the Fly ) or MSOF ( Mechanical Shift On the Fly ) ?

If you have already tested to find the front drive shaft locks into place, and the front axle is the cause, looks to the front vacuum disconnect shift motor.
Item #10 in the parts diagram below :
sscullys_1.gif

Close up of it ( this is a picture from another person's bracket that broke ) :
sscullys_51.jpg

Chances are the vacuum lines to the vacuum disconnect motor are cracked, the vacuum solenoids are not working correctly, or the vacuum to the solenoids is having an issue ( the reservoir ) :
Vacuum diagram for the shift motor
sscullys_52.jpg

The pink line is vacuum for 2WD operation ( unlocks the axle ) the light blue vacuum line is for 4WD operation ( locks the axle ).

You can test right at the vacuum disconnect motor with a vacuum gauge with the motor running. Unplug the shift motor, and check for vacuum right at the motor.

Could be the shift motor has a damaged diaphragm and not holding vacuum or has water in it ( saw that 1 time ).

Start with checking for vacuum. Also check the fuses for the vacuum solenoids, the power is always at the solenoid, ground is switched on and off by the GEM ( Generic Electronics Module ) to operate them

1994 ford ranger 4x4 hubs make grinding/clicking noise after taken out of four wheel drive


I think yours has the automatic locking hubs that slide over the the rotor hub. If this is the case than what has probably happened is a u-joint has gone bad and wiped out that auto hub.

Be prepared for some sticker shock on those hubs. they are not cheap. The usual fix for this is to replace the front axle ujoints and what ever hub is making the noise, hopefully just one.

Front right side is making a grinding noise while in two wheel, sounds like 4 wheel drive wont disengage all the way. took hub off everything looks ok. heard that it could be a vacuum problem. did notice...


Could either be a bad vacuum line or the TSB for the IWE solenoid.

If you have the truck running in park ( parking brake, chock wheels, necessary safety precautions ) check the vacuum on the front right IWE vacuum line. there are 2 vacuum hoses on there, 1 is the vac, the other is the vent, which routes up into the engine compartment, and is not hooked to anything.

Usually if it is the TSB, both sides will be making the grinding noise, as they are a common IWE solenoid

TSB : http://my.voyager.net/~sscully/file_tsb06_08_15.pdf

Operationally vacuum holds the IWE ( Integrated Wheel Ends ) out, and once vacuum is removed the spring engages the IWE.

Clicking noise in front end or transfer case when in 2wd goes away in 4wd 2006 ford f150


This sounds like the front hubs are trying to engage. This motor/4wd is real susceptable with vacuum problems. I let my oil get real dirty and it caused the low vac.The dealer performs vac test for front IWES (3c247) and found both of them leaking out of tolerance. This also caused damage on the splined contact points so they had to replace both front wheel hubs (1104)

4x4 lights come on but it does not go in what could it be


There are issues with the 4x4 system I.w.e ends ingesting moisture/water into vacuum actuation system causing no 4x4 or ratcheting outboard I.w.e ends. (Even if you don't go 4x4'n ) pull off vacuum hoses @ I.w.e ends and check for moisture/water/rust also the I.w.e is not part of the wheel bearing itself It is the part on the axle side (inboard) of the spindle. (EVEN DEALERS CAT LISTED WRONG )Many shops just replace the wheel bearing side this may fix the symptom but not the true cause of damaged I.w.e. ! Check with a reputable dealer they should have info on this condition and repair procedure.
The integrated wheel end (IWE) system contains the following:
Vacuum reservoir
IWE solenoid
IWEs (spring loaded vacuum hubs)
Vacuum hoses
Check valve
The IWE system uses vacuum hubs that engage the front wheel hubs to the front halfshafts or disengage the front wheel hubs from the front halfshafts

The IWE solenoid receives engine vacuum from the vacuum reservoir.
When the 4-wheel drive system is in 2WD mode, the 4x4 module (PCM) supplies a ground path to the IWE solenoid to apply vacuum to the integrated wheel ends (disengaging the front hubs from the front halfshafts). In 4WD mode, the 4x4 module (PCM) does not supply the ground path to the IWE solenoid, vacuum is not applied to the integrated wheel ends and an internal spring keeps the front hubs engaged to the front halfshafts.

When engaged in 4x4 hi. im getting this clicking sound while driving. stops when truck stops. its a 96 with the 5.0


It could be several things. The first thing that comes to mind is your u-joint(s) on your front drive shaft. Try turning it by hand, if it has some play in it, it needs to be replaced. There are many other things that can cause your clicking noise tho:

Ball joints
Wheel bearing/wheel hub
Sway bar links

If your clicking noise sounds more like a "electrical" click, Then you might have to try following the noise and give more details about your problem.

Auto locks for front 4x4 2007 f150 cant stop grinding noise


Are you under warranty? Make it the dealers problem if its eligible.

If the front hubs are grinding regardless of being in 2wheel or 4wheel drive it can be the hub bearings which turn regardless. If it grinds only when in 4x4 then the wheel shafts or differential or front driveshaft or transfer case is making the noise because all of these parts move when in 4wheel drive.
