I thought it was the Sway Bar End Links since the bushings were ripped but still on. I looked up to see if any other Cobalt owners have similar issues. Found one and stated it was i-shaft needed to be greased with special lube and is by the steering rod connector?

Hi,

By I-shaft, are you referring to the intermediate shaft? That is the steering shaft between the steering column and the rack and pinion.

I attached pics below of what I'm referring to. There are two universal joints on it that can make noise (similar to a clunk) when turning. If they are really worn, they could move around. Note: Pic 1 is the lower intermediate shaft. Pic 2 shows the one off the column.

Check these joints to see if they are loose or if noise is coming from them. Also, there are no zerk fittings on them to grease. So, I'm not sure what he was referring to.

Let me know.

Joe

It was the control arm passenger side lower bushing that has a lot of play and noticed the passenger side engine mount has a crack in the rubber portion but not a lot of play. The bushing for the lower portion of the control arm is 8 dollars. If you can send me the steps replacing the bushing and engine mount passenger side. As well as the torque specs thank you very much for your knowledge and to assist on this site.

Hi,

No problem. I'm just glad to hear you found the issue. To replace the lower control arm bushings, you will need to remove the control arm. I will provide those directions first and then bushing replacement. This procedure is pics 1-9 below.

The remaining pics are for the mount. You need to support the engine to do this. In the manual, it indicates to place a block of wood between the oil pan and the jack. Make sure the steel jack doesn't make contact with the oil pan. Also, the block should be at least as wide as the oil pan to help distribute weight.

Let me know if this helps or if you have questions. Also, let me know how it turns out for you.

Take care,

Joe
