Clicking noise on front wheel rubber boot torn can i fix this easy or do u need special tools

If it's a clicking noise, probably CV joint. Check for a torn rubber boot on the joint and look for blobs of grease inside your wheel (a good indicator the boot is torn).

Also agree, front wheel drive is CV joints. If its rear wheel drive and more of a clunk it'd be rod ends. Simple check for you though. Turn the car full lock so u can see in and maybe jack a wheel up. You are looking for where the axle meets the wheel. The black rubber boots will most likely be torn and grease coming from it by what your describing.
Visual inspections with components like this are easy. They are meant to look nice with no grease leaking. Torn or ripped is a sure sign something needs replacing.
One final thing though is that the boots don't have to be torn for the joint to be worn but in my experience they usually are. Best to see a mechanic anyway if your not sure.

I'm going to assume that the Yukon is a 4X4, and will therefore also assume that the clicking noise is coming from one of the two drive axles (likely the right side). Check under the truck near the wheels and you will see the drive axles with a rubber bellows boot on either end. It is likely that the boot closest to the wheel has torn and allowed the grease to escape the constant velocity (CV) joint. The boot or possibly the axle will have to be replaced.

Could be you have one of the C/V or "constant velocity" joints going bad. Would be easier on a car lift to check however look at the rubber boots, one on each end of both front drive shafts behind each front wheel, to see if damaged, torn etc. If a boot is torn and lost it's grease for sometime then the joint will give a knocking noise on turns and will need replaced.

This noise is caused by a defective outer axle Constant Velocity joint. Look under the car behind the wheel that the noise comes from and you will likely see a rubber grease boot over the joint that is torn or otherwise damage. the joint must be replace in most cases.

If you can figure out what side it is coming from, it is probably the velocity joint in the half shaft (drive shaft) going to the wheel. Please rate my answer so I am rewarded points for it.

Ticking in motor after engine heats up- do you keep your oil changed every 3,000 miles? Broken down and dirty oil will cause this. Squeek over bumps could be bad strut or it could be related to the harsh grinding noise going around turns. That is indicative of a bad CV joint or wheel bearing.
Raise car on side noise is coming from. Grab wheel with both hands and pull/push on wheel then wiggle back and forth. Feel excessive play? Grab drive axle also doing same thing feel for play or notice if rubber boot on drive axle torn or separated from axle. Usually you will feel play or notice a kind of clunking. I would say replace CV joint and wheel bearing at the same time as one will usually affect the other and both will be bad if one has went out. Not an easy fix and requires special tools. Take to a qualified mechanic, it will save you a big headache.

Your cougar is a front wheel drive and the axles are called cv joints. Under your car going to each front wheel is a metal rod with a rubber boot at each end. Under each boot is the joint that allows the wheel to move up and down side to side while putting power to the tire. If your boots get torn, water and dirt destroy these cv joints. You can jack up the front of the car and with the motor off and trans in neutral, turn the front tires to see where the damage is at. Replacing the joints on fords takes special tools.

CV joints are bad

If it makes a clicking noise when turning it could be the axles. Check the rubber axle boots and see if they are torn open. If they are that lets the grease out and will wear out the joint.
