Chris,
The crossmember pads could very well be the problem. I'm been through
all of your good & valid suggestions already. I'm not sure if 'thump' is
the right word though, I guess it's more of a 'thonk'. Almost sounds like
metal on metal. It occurs at any speed over parking lot speed. It will do
it on smooth rolling type bumps/dips and REALLY do it when you hit a
pavement lip or even a smallish heave crack or pothole. It's really
driving
me nuts. It's hard to get out there and toss the car around when you think
your whole front end is going to fall off.
One thing that I'm going to try is re-installing the valves in the stock
shocks
and try it without the Spax shocks. That should help me eliminate the
Spax hardware as part of the problem. I learned a long time ago just to
do one change at a time on supension set-ups (road raced a Yamaha
TZ-250 for many years), but do I listen to myself? Noooooo.........
