I just recently, re-found this board. I can't believe how extensiive it is. I anticipate many more posts (hopefully more replies than ?). Anyway, When I hit little bumps/potholes/railroad tracks in the road w/ the front drivers side tire, the whole front end shakes almost violently. I found if I tighten down the front shackles, this goes away a little bit. I replaced the RC9000s with EZ ride shocks. Better ride, but the shakes are still there. I checked all suspension, looks OK. I checked steering rack, looks good, no cracks still. What else? I have steel wheels, no cracks along the rims. Has anyone come across this? This is a '73 Blazer 383/350/203 with 4" EZ ride and EZ ride shocks. 35" BFG ATs 3/4 ton with ARBs F&R.
