Going to guess that this is a FWD and noise is from front and no noise while going straight?? Possible outer CV joint or loose front end part
Why should I know?
If it is a thumping and a front wheel drive car, it is probably one of the axles.
you have a bad power steering pump get a new one
Turning the steering wheel farthest left or right for a few seconds will cause a loud squealing.
Loud things starting with K: klaxon
The Drivetrain
could be control arm bushings gone bad
Could be a wheel bearing
light slapping knock is a piston knock a loud heavy repetitive knock is a connecting rod Very Bad
If its a clicking sound check your c/v joint. It gets real loud when going around a corner
Check your power steering fluid. Could also be a power steearing pump going bad
Could be many things, ball joints usually make clunking noises (usually one when turning and one when turning the wheel from turning), cv joints usually make a clicking noise and vibrate under load. Have it checked out, les schwab will do it for free (check it).
