Like the topic says, I have encountered irregular problems from my front suspension. Its sounds alot like a $60,000 squeaky box spring mattress; not a knocking sound. I have yet to find threads in regards to my problem. The scenario happens 20-30min into driving the vehicle. The squeak sounds like it may be rubber bushings on the swaybar or with the air susp. If anyone can point or help with my problem.

Had exactly this issue, yes you are correct it is bushes, happened to me on the one day we had hot weather last year and effectively the bush had run dry (an all too familiar issue if you ask me )

Get it into the dealer for corrective surgery

I was thinking of a do it yourself jobber. My range is not covered on warranty anymore so why not. Of course i havent looked under the carrage yet so we'll see what happens.
