While my clunk issue is closer investigated by the service manager in conjuction with Chrysler I can't stop thinking about it. Probably because the official statement so far 'normal noise of self-leveling shocks' doesn't satisfy me.
In the Australian forum, some customers got their self-leveling shocks (SLS) replaced with standard shocks but kept their springs. The springs for the SLS are 'weaker' as the standards ones, because the SLS act partly as a spring as well, which is required to have the full functionality.
So keeping the original springs for the SLS together with new shocks is basically a different rear suspension setup (also caused a little sag in the end).
So far the background, coming to the point:
Looking at TSB 08-014-12 http://www.wk2jeeps.com/tsb/tsb_wk2_0801412.pdf which describes a fix for the SRTs clunking in the rear, the reason (and fix) for the clunking is described as:
"When the terrain switch is in the 'Auto/Snow' position the ADS system is in soft mode, the noise is the result of the cradle moving through full travel on the mounts and returning to the body stops. This occurs over single large events at low speeds, such as sharp speed bumps. The software update made available with this bulletin places the shocks into a firmer mode for rebound and eliminates this condition."
So my question would be, could the reason for SLS clunking be the same and just because the standard springs are kept the suspension is changed in such a way that the result is the same as for the SRT fix "no moving of the cradle until body stops"?
From my understanding, SLS with standard springs is actually the opposit; softer than firmer but who knows.
