This morning, as I was opening the door, there was sharp pinging noise, & the interior door handle went slightly loose. I removed the card, & the culprit is the little tension spring on the door handle spindle. It has snapped. The handle still works fine, but it doesn't return smoothly, & it rattles a bit. Does any one know if this spring can be replaced by dismantling & re-assembling the handle assembly, or would it be easier to just change the handle assembly in one go? If it's a case of changing the handle assembly, has anyone out there got one?
