the thing that causes a clunk when you turn means that the break pad isn't turning all the way with the car tire and it is slightly knocking on the inner tire or something along those lines
Buick makes a clunking sound from trans area when accelerating.
Defective CV joint or bad wheel bearing.
If there is a clunking sound when turning a vehicle, the problem might be the ball joints in the front end. The ball joints help to support the A-Frame which helps to keep the wheel on and upright.
Check to see if your trunk is open or if the clasp that holds it closed is loose.
Have your tie rods and shock absorbers checked.
I had this too and found the answer today...apparently LINK PINS!
Worn ball joint, rotors out of round, or belt busted on the tire
sounds like the right front motor mount .i replaced mine and the clunking sound went away
if it is a front wheel drive check the cv joints
you MIGHT put a little more effort into your question - details &H specifics never hurt. in a front wheel drive car, bad , loose CV joints clunk upon turning.
Probably your u joints or the rear end has too much slop.
Tie rod might need replacement.
