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.
I had this too and found the answer today...apparently LINK PINS!
if it is a front wheel drive check the cv joints
Worn suspension parts - struts Loose strut mount?
Check the strut mountings Check springs and shocks they may be worn out
A bad ball joint or tie rod end.
Buick makes a clunking sound from trans area when accelerating.
cv joints
When you turn the wheel, or while you drive?
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.
Defective CV joint or bad wheel bearing.
Check the front brakes and wheel bearings first. Then go to the tie rod ends and the rest of the front end parts to see what is worn or loose.
