Hearing a grinding noise in the pass side wheel. have noticed when making a turn that the cv shaft is clicking as well but this grinding just started. Have jacked up the front and turned the wheel by hand but cant isolate the noise to either the cv shaft or the wheel bearing. it is a constant sound so I am guessing wheel hub/bearing but would appreciate any other input.

CV joint? Is it louder when turning?

This due to either a worn wheel bearing or a worn front drive arm.

The most common cause of a grinding noise when turning is a worn front wheel bearing. What happens is that the weight of the car is shifted on to that wheel as you make the turn causing the worn bearing to make a grinding noise.

Cv shaft is bad, ( drive shaft from Trans to wheel. )

Could be CV Shaft or Hub Bearing as well. Jack up the front of the car, support with Jack Stands and check for play in wheels/hubs/bearings/linkage by grabbing wheel at 3 and 9 o'clock positions for tie rod ends and steering linkage, then 12 and 6 o'clock positions for bearings. You should barely be able to feel play. If you think it is more than acceptable climb under the car while someone else performs the tasks above. Turn wheels for excessive brake noise or out of tolerance discs. Out of tolerance discs will cause premature brake wear and cause pads to move around in the caliper sometimes before starting to grind. Finally, and what I think you're hearing/feeling is the CV Shaft. Grab shaft, move around feeling for excessive play in joint or splines on each end. Turn steering all the way lock to lock and turn wheels at each lock, forward and backward, feel/listen for clicking/popping. Most of the time you can quickly easily diagnose bad CV Joints in a parking lot by slowly, safely driving in a circle forwards and backwards making the joint noise more pronounced. If it is a CV Joint, my advice would be to spend the extra few bucks and replace the whole shaft while you're there. Its quicker and easier requiring less specialty tools to complete the job.

Grinding noise upon turning is normally one of two issues. First, and most often, it is caused by a worn out outer CV joint. If your vehicle has more than 50000 miles on it and the axle shafts have never been replaced, this is what I would suspect first. In addition, CV noise will be louder when turning under power (gas pedal pressed) than when coasting into a turn. The other possibility is a front wheel bearing assembly. These are not as common, but do wear out as well. The wheel bearings will usually make no noise when going straight, but will make noise upon even the slightest side to side turn. CVs on the other hand, usually grind only when going into corners or making left or right turns. If you suspect a CV joint, but don't have high mileage, you could have a torn CV boot that resulted in the grease that lubricates the joint being depleted and causing the noise. You can inspect the out boots visually for tears....grease leaking out usually leaves telltale spatters in the wheel wells also. Replacement of the CV joint can be done, but it is usually cheaper to replace the entire axle shaft as they are serviced as a unit.

Assuming that you have already ruled out the brakes, severely worn engine mounts can transmit vibration and noises from the engine which are not normally heard. You don't say in what I see but is the vehicle two or four wheel drive. Since you mention CV half shafts I have to assume it is at least front wheel drive. If the vehicle is four wheel drive then there is a front differential with bearings in it that may be at fault. Have you done both sides when you say "hub assembly". Defective hub bearings will make grinding noises which will change tone or intensity when turning, accelerating or braking however the noise is usually fairly constant unless they are only just starting to fail. CV joints don't normally "grind" unless they are really bad. They usually make progressively worse "clicking" sounds or "clunking" sounds especially when turning hard, changing gears or direction of travel (forward to reverse and back again). Do you have non-stock tires/wheels? Larger/wider than factory spec tire sizes can rub the fender wells when the car is moving or turning. Another thing it could possibly be is the air dam below the front bumper. If it is loose it will push down in the airstream while the car is moving and rub on the ground.

unlikely to be a cv joint
more likely a disc pad worn out or a failed wheel bearing

I have heard a lot of dry outer tie rod ends and ball joints causing this problem. Ford used non greasable front end parts in those years.Could also be in the strut mounts. Get a second opinion. If it makes the noise sitting still it should be easy to find with stethascope or chassi ear.

Replace CV joints, or half shafts. Half shafts are much easier, and the cost isn't that bad after you exchange the old ones.

Yes sounds very likely to me.

Only other thing I can think of is a worn suspension bush, your car has been lowered (modified) too much or the suspension itself is broken.
