When I pull the outside levers on my 2 front doors they take a few seconds of wiggling to open the door. Is this a simple matter of taking the panels off and adjusting the inner rod mechanism like this video tries to show? Or are there bits such as springs in the lock mechanism itself that need to be replaced such as this website shows? Are there better tutorials out there for this fix? Will I need any extra parts like plastic pins that might break when I pull off the interior door panel? Thank you!!
