The sound may be more noticeable when driving up a slight grade with little throttle input. <\/span><\/p>\n<p class=\"western\"><span style=\"font-size: 12pt;\">The warble sound may be due to the bushing in the left-side differential cover having too much clearance. If the condition is found, replace the left-side differential cover and shaft seal.
