SOURCE: Front right side is making

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.

SOURCE: 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.

Have grinding noise in the front area of the vehicle...changed right and front wheel bearings still has a light roar....this is a 4x4 truck... please help


what type of vehicle,auto or manual hubs, check front u-joints. since you replaced hubs i imagine you inspected brake parts and rotors. could also be a wheel bearing in front pig. (carrier bearing or pinion shaft bearing)

Front wheel noise when driving. Louder the faster you go.


Raise the vehicle until one wheel is off the ground. Grab wheel by sides and wiggle - if it moves, you may have a bad wheel bearing. Also try rolling the wheel and listen closely - you should hear and feel a crunching or grinding noise which would confirm the wheel bearing. Lower vehicle and check the other side. Many newer vehicles have the bearing as part of the hub, requiring the replacement of the hub assembly to fix the bad bearing. Most others require a press to change out the bearing. It may be worthwhile to take it to a shop right away for a hands on diagnostic. Be careful driving it - the wheel bearing could potentially cause the wheel assembly to fall of the vehicle, injuring or killing yourself or others!!!

Vibration/Humming/Grinding noises when stopping or turning left.


when turning left vehicle distributes weight to right front wheel bearing causing load. since u describe a noise in right front while driving straight i would suspect failed right front wheel bearing. see if your noise changes/goes away while turning right that should tell u 4 sure

1. I would suggest that you engage your 4WD while you are in full stop and/or safe range of 5mph, however as claimed by the local dealers your vehicle is capable of engaging even while driving. Engage your 4WD while moving only when necessity requires.
2. That clicking noise while turning extreme right or left would be the birfield of your axle and would only mean your front hub is still engage even though you have disengaged transfer case.
Have your front hubs cleaned of old lubricants or grease due to non usage. dont use grease as lubricants, use thick oil such as gear oil or silicone oil. and use your 4WD every now and then.

Do this first then check if you still feel somtehing is loose on your suspension and others.
