Worn suspension parts - struts Loose strut mount?
front wheel drive
When you turn the wheel, or while you drive?
Buick makes a clunking sound from trans area when accelerating.
Could be the front wishbone. Mine was making similar noise, especially over bumps. Not a major repair - approx €250 euro
Worn out front shocks and struts will make a clunking noise when you go over small box. The strut may actually allows the tire to hit the fender well.
Check for looseness in the front axle u-joints.
It's either something loose or something worn out. I'd start with the shocks then look at the ball joints.
if it is a front wheel drive check the cv joints
yep
Bad strut? Bad strut mount?
it would be the CB joint it it's a front wheel drive vehicle with high mileage.
Type your answer here... if it is a front wheel drive it could need c.v.Joint's. Just a thought
