The SLS isn't really that complicated. If you an reasonable DIYer you can replace the accumulators without too much problem. Try doing a search on SLS or accumulator or spheres, that should get you planty of reading to get started. The wagons are basically the same as the sedan with SLS, just the layout is a little different.
