more on level up system - went to look at the hydraulic rams and noticed that I have a "mix" of grade 5 bolts and grade 8 bolts used to attach the rams to the frame. So now the question is what should they be? Guess it is time to contact Keystone and Lipperet to see what is suppossed to be used. And given that I have a mix, I can't trust that the nuts used are the correct grade either. Why me? My input to the rest of you is to look at your leveling rams to see what bolts were used! Grade 5 bolts have 3 lines radiating from 3 of the 6 points on the bolt head. Grade 8 have 6 lines, one from each point on the bolt head. And then the next question to Keystone/Lippert is what torque value was supposed to be applied to the bolts. John
