Crab needs to be removed before main gear touchdown and not after. Touching with crab on a dry runway imposes severe side stress.The gear can take impact loads but is not designed for side stress. On a wet or slippery runway if you touchdown with the crab the aircraft skids straight on which reduces the sideway stress and then due to CG position straightens automatically. On wet runway Landing with crab prevents premature removal of crab with downwind draft which will result in a GA.
