ok my steering wheel shakes at all speeds slow and fast. it's more exaggerated at slower speeds. i replaced my left balljoint and right tie-rod and both wheel assemblies feel very tight. i put the wheels back on and this problem is still there. i got an allignment and it's still there, so what would be your suggestions? both parts that i replaced did in fact need to be replaced, but i wonder if those were the effect of this problem. my tires are about 5 yrs old.
