2 ways to test the drop links -
1. Jack up the car - or put 2 wheel on the pavement reach under grab the drop link - if you can shake it and it clicks then it is FUBAR.
2. Remove one end of the drop link (requires spanners) zip tie the other end safely out of the way, go for a SLOW drive, if the rattle is gone then they are FUBAR
Even with a pry bar it is hard to test the banana arm - even some mechanics miss it, the correct procedure is in the manual though
