4-in-1 Axle Caps from Olson & Company. Sold as a pair.
Sometimes you can't tow a bus or semi-truck tractor backwards, you can't pull the drive shaft, and you just have to pull the axles. These caps are equipped with an oil-access hole for adding oil to the hub prior to towing to prevent damage. Pull the axles, place caps, add oil and tow!
Axle caps fit most 8-bolt tandem and single-axle trucks on the road today. This is a very popular hub pattern.
