Thanks guys, so no sls thankfully!
All 4 shocks are completley shot, I brought this up with the dealer I bought it from and he areed surprisingly, to pay for all 4 corners, parts only ofcourse. He will be sending me the shocks.
From doing some reaserch sachs-boge or billstein is the struts/shocks to get.
