Yesterday as I'm adjusting the valves on my car I notice that something is a little off with the driver's side trailing arm. I reach up and wiggle it. The inside end of the trailing arm can move a quarter inch up and down (6mm for Sir Andy). Great, I have to replace the thing, and only one day to get new parts shipped.
I was under the car 2 weeks ago, fiddling with shim stacks and am quite sure there wasn't any problem then, so I suspect the problem was at the breaking point when I started the dual AX / DE weekend 2 weeks ago. It must have let go the 2nd day.
So I guess I am saying, check bushings often if you still have originals.
Many thanks to Ira Ramin (of Tarett) for getting me a set of replacement bushings tonight.
NOTE: I did not move that broken bushing, that is how it came out of the car.
