Hey guys, thanks for joining!
The problem with rattle was on standard shocks (3 TSBs out to fix it and looks like one of those was successful), SRT shocks (1 TSB out and a computer fix, which was apparently successful, too ) and the SLS (by the way SLS stands for Self Leveling Shocks, no a formal Jeep abbreviation).
First of all, the rattle can also occur when other suspension parts fail like worn bushings etc. as well as have other causes (somebody had loos tools in the spare tire compartment). Only proof that it is the shock is to replace I with a new one and see I the rattle is gone (not my preferred solution, however).
By the way there is no computer involved to these shocks, only to the SRT ones (for adjustments of the dampening) and the Airsprings. The SLS are a 'regular' shock which levels the car by the pumping effect during driving. Basically the shock pumps itself back up. No other power than loading the car is necessary. Lots of people get confused and mix them up with the Airsprings (they are adjustable using a compressor).
You can exchange SLS with regular shocks, just be careful to replace the springs as well. They SLS are taking some of the spring work, so the spring that comes with the SLS is a little weaker. As a result, your Jeep will sag if you don't change the spring.
Hope that helped
