I left on a trip this morning with my wife and grandson going out to Yellowstone national park, somewhere in New Jersey I noticed a clunking sound almost like it was coming from the steer safe on the left-hand driver-side. I stopped and noticed the LH spring was about 1/16 away from the lower A arm. The RH side had a 1/2 in clearance. After several rest stops and spraying the springs and noticing a loose bolt a on the upper RH shock mount which I tightened, the noise was still there, so I started looking at the steer safe again. Next rest stop I noticed a square bolt with a stop nut that looked like it backed off 1/4 in. As I tightened it,it would pivoted the spring away from the Arm. Called steer safe and they verified that was the right thing to do. Drove about ten miles or so with no noise an all of a sudden it was back again. No vibration in the steering wheel just had the MH aligned 2 years ago and front end parts replaced. Anyone have any thoughts about this problem?

. They have been replaced with HD springs from Henderson.

I have the coil springs in the front, but at this point I am open to any suggestions of what is causing this banging noise. It is very frustrating after 3000 miles of travel and spending $350 at a chassis shop that noise is still there.

The bracket was hitting the frame. There were some factory holes to mount the brackets one hole lower to clear the frame and barely changed the angle of the sway bar which solved my issue. Probably not your issue but maybe helpful for someone else. Cheers Doug
Doug what chassis did you have. When I looked at my P30 chassis the sway bar is attached to the AArm and frame the upper supports are riveted on. Are you saying the upper bracket was loose and banging into the frame?

After driving about 300 miles the banging noise is back. This is really discouraging after spending $330 on the front end. I figured they had to drop the lower A arm to reseat the coil spring but I don't see any evidence of that.The grease is still in place around the nuts. So far this trip it started with the front end noise,then the WH went out now I can't get my generator to idle correctly. These things are easier to fix when home than on the road.

I can,t see how this didn't cause a problem before now or how a pot hole could unseat the spring, but after driving several hundred miles the banging has gone away.
Don't you hate it when a problem goes away without finding the cause? Some HD springs sit on a plastic isolator pad to minimize noise. Perhaps this pad has shifted or maybe you can compare the right and left sides and see if anything is missing/different. Hopefully the noise will not come back.
I learned that cars have this plastic/rubber but the trucks or MH do not , they way it was described to me is that the top part of the spring is suppose to sit in a boss and was not so it would bang when the control arm moved. I thought I was hearing a spring type noise that is why I thought it was the steer safe. Just glad it is gone now on to my next problem my generator.

Gjac wrote: I think I have finally figured out this noise. When I went to remove the springs and began to loosed the end nut I noticed there was a gap between the lock nut and the yellow pivot bracket , as I continued to loosen the nut all of a sudden the spring would spring the eye bolt in causing a noise and vibration. What was happening was the treads were hanging up then releasing suddenly every 1/8 in or so. I back off the nut all the way but there was still tension on the spring so I did not remove it instead tighten it all the way so the threads could not hang up. Will we if this works or not.
Hopefully that will solve your problem. It may require you to readjust it so it keeps the wheel centered while going down the road.
I was overly optimistic that banging noise is back. I think it's time to find a chassis shop, any one know of one along I 90 in SD? I probably need a new thread for this.
