ensure your wheel nuts are secure.
check your tyres for stones /nails etc

If you hear sound when you turn the wheel but the car is stationary
I would advise you visit a tyre /steering /brake specialist if you cannot locate the source of the noise.

Ensure the wheel nuts and Axle nuts are properly torqued to the specification. Lift up the front wheels, place supports under the car and do the following:
- Sit if front of right wheel, slightly move it right and left and feel any abnormal noise if coming out of it. If click-click or Tuck-Tuck sound is observed it could be due to the excessive play in the tie rod end, rack end, ball joint wheel bearing or U joint. Next hold the Tire with your one hand at the top and with other hand at the bottom. Shake the Tire inside out and feel any noise or play. If play is observed, it could be the worn out ball joint or the wheel bearing. Now hit the Tire at the top with rubber hammer and observe any rattling noise coming from near the center of the wheel. If you could listen to the extra noise it could be due to the dried up caliper pins. Grease the pins with graphite grease. If all is found fine, similarly check the left wheel and repair as necessary.

It sounds like a ball joint is worn, possibly the rack end ball joint or tie rod end.
With the bumpy ride it could also be that the front shock absorber has failed.
Jack the front wheel up on each side in turn, grab the wheel at each side and shake it back and forth as hard as you can. If you hear or feel looseness, the problem is in the steering, as above.
Then shake the wheel while holding it at top and bottom. If you feel looseness then, the problem is in the front suspension wishbones.
Repeat this on the other front wheel. Let it down on the ground, then bounce each front corner up and down as hard as you can (you might have to have a second person with you doing this). If you hear a clunk or feel excessive bounciness, it is the shock absorber. When bouncing like this, the car should resist, and not keep bouncing when you let go.

It is common for the front sway bar links to wear out. This can cause a sense of looseness, with a slight rattle in the suspension when going over bumps, or when making turns. They cost about $60 a pair at auto supply stores, and can be changed in about 1 hour. There was also a GM technical service bullitin on this vehicle in regards to the steering column which is also a possibility, as well as one regarding loud knocking sounds related to the front strut spring cups.

well the knock in the steering wheel is a common problem for your modle your steering nuckle needs to be removed lubed and replaced this will resolve this issue....as for the other noise i would have to hear it noises are tuff have your ball joints checked and lubed if posible ......good luck

there are many possibilties. Sway bar, sway busings, shock, tire, something in the brake pad, wheel bearing, the list goes on and on. Best bet is to let someone qualified to take a look and determin what's wrong before hundereds of dollars are spent without the cause being fixed.

its in the stearing shaft that comes off the gearbox and connects it to the column there is a aftermarket shaft that has a grease fitting to stop making the noise

heve you checked your steering fluid? if the fluid is of check the bearing of steering pump and also the bearing of the tensioner.

You might have the lower swing arm bushing checked mine slid of the bushing but stayed in the cradle on the passengers side.Only made noise when ibacked or turned sharp left.
