Little Hickup this weekend on working on the Suburban. Thursday night the Yukon started making noise on the drive home from work. Friday morning the garrage smelled like gear oil, so I looked under the Yukon and found a large puddle of the offending odor under the rear axle... a lot more than what could come from the pinion seal...
Boom!
looks like somthing internal impacted the cover.
and the culprit is stuck in the hole... pinion tooth.
