    their is another part that is called the acutator and it is a bit more than a transfer case. I had to replace mine just recently as well and will cost around 600 for just the part. Depending on who works on the vechile would depend on the amount of labor. I would have the vechile checked out by a ASE master technician to determine the true cause of the problem. Best of luck to you and soory i could be more help

It sounds like you blew the pistons out of the calipers and locked up oyur front brakes completely. Best solution is to do a complete brake job. pads, rotors, calipers to sovle the problem.

When I drive there is a loud grinding noise in front right side by tire, what could this be?

It could be a number of things, could be the brake disc grinding up against the Caliper, or it could be a wheel ball bearing, those are the most likely since it's a metal on metal sounds, my bet would be the disc brake though. Caliper might need adjusting, or your pads are worn down and rubbing against the disc. Hope this helps.

Why am I experiencing a vibration or grinding while turning?

get the car serviced and diagnosed? noise finding takes hands on work. not guessing.
do you need list. and are you a hands on person? many here are not just looking for wild guessing. which are you>?

i cant even guess. as you never said what corner or car makes noise. kinda key to Discovery. and cause.
my guess its the front. end.
bad brakes.
bad wheel bearings
bad U-joints. up front.
disc caliper pistons stuck or the guide pins SEIZED.
Disc rotor damage of any kind. (inspections find most of these)

tires with too low pressure can cause odd effects. truly odd.
one tire i had , had side wall deformations, (cheap tires , factory 2nds by previous owners) and when low, they make steering wheel ripple effects///, the most odd thing ive ever seen, not 1960 when this happened all the time. (nylon cord tires or worse).
Inspect tires for damage or low air pressure, (every 30 days)

but grinding is bad news, any machine that grinds, is the sign of doom. (metal against metal dry)

the rule on noise, is LOCATION , it's exact location.

I had a constant grinding coming from front passenger tire. Replaced Caliper and put the worn pads back on for a day, the constant grinding went away. It would still grind while braking,hitting a bump

It sounds like the brake pads are metal to metal, when you turn the flexing of the wheel makes them touch the rotor and grind. This can rarely be caused by a badly worn wheel bearing as well, have both brakes and wheel bearing inspected.

When im driving the front right tire sounds like its scrapping against metal could it be a c-v joint

It could be, another scrapping against metal sound can be from the brake pads, hub protector plate touching the rotor bt a c-v joint sound is both metalic n clattering at d same time. Being physically present to hear the sound helps. Have a mechanic look at it to be sure which it is.

Front right tire makes a grinding noise , hub assembly has been replace problem stills there, what will be the problem?

It could be a lemon replacement hub or it could actually be the tire. Check the tires tread for irregular wear patterns. If the hub was loose prior to change this could easily cause the tire to wear in a "choppy" fashion which can also cause a rough humming sound that I have often heard customers refer to as a grinding sound.

Front end grind

Sounds like a wheel bearing.

The front passenger tire is wearing vairy hard on the outside tread. Also when I'm turning the vehicle I can hear some grinding and squeaking coming from that side of the axel.

Sounds like tracking does the other tyre have the same problem?

It could also be the bush or trackrod end it is possible that your rubber boot has split and has no more grease inside and you can hear metal against metal.

Its time to take it in tracking first then check the CV joint and all the rubbers for wear if so they need replacing

Front grinding/rubbing sound when accelerating

if you slide under the truck and try moving the cv with your hands and there is any looseness in joint or noise the joint is indeed worn out, the cv joint if bad should not stop the truck from shifting into 4 wheel drive it could be stuck in 4wd and this would cause cv joints to break, if u have access to lift get all tires in air and try2 vs 4 drive and see if tires turn if not lift front tires off ground tires should turn freelyin 2wd, as u turn tires listen to wheel bearing and shaft noises for grinding clunking indicating bad parts, simple tricks that may help u find problems for cheap good luck!!

Anti lock light came on

You have a serious brake problem, most likely the front brakes are metal to metal, have it inspected ASAP, many brake shops and tire stores do this for free.
