Replaced shock absorbers. The pins that hold the absorbed in place are MUCH more difficult to access, remove and reinstall than shown in instructional videos. I accessed the shocks from the front of the machine. It looked like it would be harder to do it from the back. Had to improvise, using long shank screwdriver, long (approx. 12") piece of wood and a hammer to drive pins OUT from front to back. To reinstall, I reversed the pins and drove them IN from front to back. The plastic tube and rubber collar, disconnected for access purposes during shock installation, were a problem putting back together. To make it easier, I used a stainless steel adjustable hose clamp in place of the original spring steel clamp. Oh, almost forgot, I used petroleum jelly on the pins when reinstalling. Hope this helps others that might face the same problems I encountered.
