Rear axle. I keep a spare diff to swap out quickly, incase of bent axle or chewed spur. Bearings eventually get full of fluff,tyre crud and wear out. It's good to keep some spares.
Not mine, but I've seen servo savers break, also bent front stub axles, plastic servo posts, bosy posts and bent long spring carrier bolts.
