I have the front end out of the demon making some changes and I'm wondering if I should be looking at my manual steering box while the engine is out. The car wanders and darts around more than I think it should with no real on center feel and it has all new steering and suspension parts (rubber- not poly)- just the box is untouched. It has been aligned a couple times with more caster (2.75 deg) but all this could be for not with me running polyglas tires. The box itself doesn't seem to have any percieivable play or problems but is there a method to tell for sure?
I'm all for rebuilding, replacing it, whatever the case may be, but I don't want to piss away the money if there is nothing really wrong with it- but how would I know?
