Hi - new to posting here so I am unsure if this is the correct area. We have a 1985 Palomino that for the most part, is in great shape. We are unsure though if the the extender/lift arms (I’m sure I am using the wrong term) that should be providing support are actually fully extending. The front right one does - the other three don’t appear to lock in a fully straight position. Is this normal? Thanks in advance!
