Replace the lock washers by normal ss or brass washers and use double
nuts, providing there is enough thread on the studs. Fut using anti
seizing compound. Also replacing the brass nuts with ss items may do the
trick.
The brass is fairly soft and the lock washer will work its way into the
surface of the nut, thus creating some play over time.
