When i put it in reverse the back drivers side tire locks up checked to see if it is free and it moves what would cause the problem and how do i solve the problem put different moter in and it dies when in revers and it cuts out what would be that problem and how do i solve that problem

There's something seriously wrong in the transfer case or controls. It seems the rear driveshaft is locked up, and the front wheels are driving. The driver's side rear tire is skidding because it's trying to turn backward - rear passenger rear tire is going forward and rear differential has no option but to turn the driver tire in reverse (driveshaft locked). DON'T TRY TO DRIVE IT. Get it checked out and fixed.

Your transmission needs to be repaired. This is going to be at a starting point of 1700.00 and cap off at about 2300.00.

it appears that the brake is faulty and when in forward direction is putting itself on. It is free in reverse. check the brakes are in good condition and properly retained

Your problem is a bad CV axle and outer carrier bearing failure. The grinding is coming from brake rotor on that side due to the bearing failure. the brake rotor and bearing is causing the lock down. Do not attempt to drive or further damage will occur. Transmission is probably OK. Replace both sides (CV axels and Carrier bearings, 150,000 is time) Check brake components for damage and replace pads while you are there.

sounds like you have a brake pad hanging up your shoes probably need to have brake shoes checked and adjusted

put the car in reverse then rock it back and forward to release the brake.

the tie road end + rack end is the main proplem for making your tire wearing off
the noisy at slow speed coming from tire
you can check that by make the tire free by putting the car on the lift then you catch the tire from side and try to move it (in-out) if its move that mean you need to change even tie road end or rack end or both

remove the rear wheels and inspect the braking system. something is loose or has been bent to stop you truck

check the emergency brake to make sure it is not engaged and check to make sure that you don't have a caliper hanging up or a bad axle

sounds like the parking brake cable is stuck on the side, the first step, and the easiest step it to locate the cable behind the tire and really spray it with "WD-40" or "PB Blaster". That is to see if the cable can become free. If that doen't work, than you have to manualy de-adjust the brakes, ny locating a small rubber plug, rectangular in shape and using a brake adjusting tool, (availabel at most auto part stores) to "turn back" the adjusting screww inside the drum.
