Are you talking about the front ones or rear onesIJ Do you have good Grade 8 boltsIJ Have you checked for play where the hex drive shaft goes through the cams that drive the sievesIJ Have you checked the hex bearings and flangesIJ We have had your problem before, and have solved it by doing the above mentioned things, but I also know that Case sells a kit to slow down the sieves on early 2188 combines that we may look into. Also Heartland repair in Ross, ND sells a kit that moves the rear axle back and shows you how to check for contact in other areas of the chaffer_sieve setup. You can find that if you search for "CSR kit". Good luck
