It's been a steep learning curve on my new to me A800 mmcx. Nice car, but took some watching videos to learn how to properly refill dampers. I'm pretty much done, but I just noticed that there are no small bolts on the uprights that clamp the wheel bearings. My used car did not come with them. How important are they? I did add the crush collar between the wheel bearings and I have less slop now. Thanks, Glenn
