Clanking noise after turning and sometimes when turning

You don't say, Front or rear wheel drive. First check oil level, On rear wheel drive check the thrower plate on the tail shaft at the diff end is not bent and rubbing on the seal, A dry oil seal can make this noise.so can the U/Joints. on front wheel drive , check the cv joints , dry oil seals , the drive shaft inner cv joints have a thrower plate that may be bent. worn or binding brakes can make this noise also.

One wheel turning faster than the other is normal if both wheels are off the ground. If one wheel is dragging when the other wheel is on the ground, it could be brakes or a wheel hub bearing.
Usually if the noise happens on right turns, the left hub bearing is failing, and vice versa.

Accelleration noises of the magnitude you descibe makes me think the engines crank shaft bearings have gone. Has the oil pressure light come on recently and what's the oil level like.
Without being there to hear it, it's very difficult to diagnose. You should detect noises and rattle if you rev it when in neutral if it is the engine. If the engine is smooth in neutral and the oil is good you may have a bad diff or cv joint

hi.
a transmission problem when hot, but ok when cold, would suggest that the oil in the gearbox is getting too thin when it heats up.

you say that the transmission has been pulled out but do you know if the oil was actually changed in it.
if the oil has not been changed, drain it and replace with the specified oil.
if it was changed recently, then i would consider using a thicker grade transmission oil instead.

changing gearbox oil, is normally a matter of removing the drain plug on the bottom to drain the old oil, and then refilling using the level plug on the side of the engine.

Probably your wheel bearing.

The sway bar linkage probably came undone on one of the sides. Wikipedia has a picture of what your sway bar linkage may look like:

http://en.wikipedia.org/wiki/Sway_bar

That is a picture of a Porsche sway bar, but the idea is the same. Make sure all bolts are tight and that one end is not missing the linkage that connects it to the spring/strut. The grinding of the brakes may be the sound of the linkage piece touching the rotor. Sway bar is a logical solution to both issues.

If that doesn't fix the issue, put the front end of the truck on blocks or jack stands and have somebody wiggle the tire up/down and side to side while you inspect the mechanical components underneath. Other things to check may be the ball joints, tie rod ends and suspension bits.

Check your suspension bar and check your front strut assembly, jack up the side you here the noise on and pry against the tire to see if you have any movement between the strut housing and the frame, make sure the top strut nuts are tight, if they are next check tie rod ends to see if you have any play, next pull the wheel from the top and bottom to see if it's loose if it is watch while someone else wiggles the tire, you could have a tie rod loose or a king pin loose. Also it could be a wheel-bearing nut. Let me know what you find so I can tell you how to replace it.

IThis car im not sure if it is front wheel drive or not. Assume it is then it could get expensive. If it is just rear wheel drive then its just packing bearings with grease, no big deal.

if it's a 4x4 you need to replce the axle on drivers side

CV joints yes look at the rubber boots for damage. You can get a replacement boot but if you do remove all the old grease to remove any dirt that is cousing your problem.
