Sounds like you've done a lot of work that'll give you some longevity with your front end for a while. How about the shocks? I know it may seem too simple, but a set of bad shocks is gonna make your ride ugly, "most of the time", as you mentioned. I'm hard pressed to think that it's just your cv's moving up and down all by themselves <img src="/forums/images/graemlins/confused.gif" alt="" /> and not the whole a-arm assembly and wheel too. If the shocks are shot then your gonna get a whole lot of extra movement to the wheel with the lack of dampening. That'll definately cause you to feel a shudder or vibration while driving. Probably noticing a bit of drifting or play in the steering? Just some thoughts. BTW what size tire ya runnin'?
