This might sound really obvious - but often the most simple answer is the right one - have you checked all the ballstuds?
I had a slightly loose centre bridge hex ball and it gave traits similar to what you are describing. The stud would "fall" a little left or right (and stay that way) until the next big steering input. Would cause it to wander on the straight.
Also check your uprights and make sure the threads are still good. If the bottom 3x10mm CS screw gets loose this can also happen. Sometimes the thread gets a bit crap and it will never stay tight. Time for $5 of new plastics!
If you are checking your steering on a setup station - make sure you check the throw is even inside and outside also. ie: measure the left and right throw per normal, but then check it inside - left hand wheel angle when turning right. With typical Ackerman settings should be mid/high 20's at outside and mid/high teens inside from memory (assuming near full throw, so >80% DR)

Good call actually, with enough vibration those do tend to slip and slide around the place. will check this too.
I don't run a servo saver (those are for toys not 419's)
Thanks again

I guess you've seen me bashing my 419 in a Walmart parking lot somewhere. I'll go throw money away somewhere else then.
My Tyco RC cars don't have leaky diffs or sticky servo savers...but they don't survive contact with parking blocks very well either.

Or anywhere with some serious speed. Just wait until you hit something (or something hits you) and you find your 100$ servo (or worse) verschnickered. 10$ is cheap insurance for a 300$ servo. Volker and co are sponsored, they can afford to crap any of their equipment. If you're in the same boat, good for you, habibi, but my feeling is that a lot of good gear gets bad reviews here only because the users are knobs who want to emulate things they see on youtube or read on forums completely unencumbered by any thought process.
