87 Gl wagon...okay..this is progressively getting worse and i cannot seem to pinpoint what is causing it...i checked all my wheel bearings and they are solid..both front axles are good...i cannot feel any vibration at all when turning left or going straight but as soon as there is a load on the left side(when turning right) i get this vibration i can feel through the floorboards...instinct tells me its coming from the front end somewhere...just could use a bit of input here...thanks all
