I Just had my. Alternator and surpentine belt done ..i still have squeeling and a clunk. When i make a right turn sometimes..

Year/make/model/mileage? Squealing when exactly?

Squealing and clunks when turning is probably a suspension or wheel bearing kind of issue. Nothing to do with your alternator or serpentine belt.

Does it ever happen with the vehicle parked, idling or giving it a little gas? If so, suspect some belt driven component. Check your power steering reservoir if hydraulic instead of electric. It would have helped if you had mentioned make/model/year of vehicle.

Squealing and clunk could be two different things. Was a new belt tensioner put on? After a certain # of miles, it is good to go ahead and replace the tensioner when the belt is replaced, depends on the particular engine but generalizing I'd replace the tensioner too if it's over 75K mi.

Clunk turning is more likely sway bar mounts or end links, or ball joint, or shot control arm bushings, or strut towers, unless it's a repetitive clicking sort of clunk then maybe CV axle. This assumes no collsions which could put the suspension geometry in a bind or break something.

Jack it up, pull the wheel, inspect and poke/pull/pry (including during and after a helper (if available) is turning the steering wheel to that direction) on suspension components.

check the fluid level in the power steering, the pump bearings. and alignment. could also be a wheel bearing / tie rod / suspension issue. where does the sound come from? does it change with the rpm of the engine?

The description of the problem only sounds vaguely similar to symptoms I had a year ago. I could switch on the AC when the car was parked, or simply put it in reverse. Belts would squeal, even if not loudly.

What we discovered was this. I had a leak in the high-pressure power-steering hose, which is situated close to the belt-driven components. The Dexron power-steering fluid leak was lubricating the belts. And all that time, I'd been asking the mechanic to tighten my belts, but they'd come back and say the tension on the belts was just right. I can't understand why they didn't locate the problem with the PS hose. But I have a new mechanic now, so . . .

Mindless1 seems to have a better answer for the other "clunk" symptom.
