It first started under warranty. They first lubed the steering column which lasted 2 years, then after the sound reappeared, they replaced the steering column. Now 2007 it has returned again and they will only fix it, if I agree to pay half of the amount and agree to have major gasket repair work down at Ewald Chevrolet in Oconomowoc for $850. Ewald is a crook. They went fishing looking for anything wrong with my car and came up with a bad gasket. They said to prove that I am a loyal customer and am acting in good faith I should agree to have them perform all of the work. This has nothing to do with the steering column noise. I had the knocking noise since I bought the car new and now Chevrolet will not repair this ongoing problem. They stink, their product stinks, I can't wait to sell this Impala and will never own a Chevrolet again. Going Toyota from now on.
AnswerI've been told a brace behind the dash made of molybdenum (or magnesium... can't remember) can give a loud crack/pop sound. I know about the problem in the answer above - that one is more of a dull , muted clunking sound. If the one you're talking about is very loud, a single pop/crack, and not happening very often, it's most likely the brace. It's not supposed to be an issue, just expansion/contraction.I have a 2001 Chevy Impala and experienced this same problem. The cause of this noise is the steering shaft. While my car was under warranty I took it in and was told there was a Technical service bulletin (TSB) requiring the shaft to be re-lubed, as with your car after a while the noise came back. With my warranty now expired I took the car to my regular mechanic who changed the shaft out solving the problem for about $120.00. The TSB had changed from replacing steering shaft to just the lube (cheap temp. fix).
The sound of knuckles cracking is caused by gas bubbles rapidly collapsing in the synovial fluid in the joints. This release of gas creates a popping or cracking sound.
The popping or cracking noise heard when "cracking your knuckles" is caused by synovial fluid filling the vacuum left by the joint's displacement.
by cracking a bone, popping it the wrong way, landing on it wrong. the possibilities are endless!
This noise, unless, painful, is due to air in the joint. See link below about joint popping.
Because your bones and muscles are tight and sore, they make noises and are popping or cracking. Hope this helped!
Its because of pressure when you walk. i have these alot and quite frankly, i enjoy it!
It is residual energy, i believe. It could also be spirits.
Cracking your knuckles does not directly cause arthritis. The sound is produced by gas bubbles popping in the fluid within the joint. However, repetitive and excessive knuckle cracking can lead to joint damage and weaker grip strength over time.
Tiny bubbles of gas, which is made of nitrgen and oxigen build up in the joints. It is these you hear popping to make the cracking sound.

The carburetor has an electric choke that is possibly shorted.
You are referring to crack cocaine. It is the crystal form of cocaine which is heated and smoked. When it is heated, it makes popping or cracking noises.
