A couple more tidbits of info that is often posted incorrectly here; 1) it is often recommended to new owners to grease the wheel bearings, but the original
Uhaul bearings are sealed units and can not be disassembled or serviced in any way, 2) it is also often recommended that spare wheels / rims can be purchased from Northern Tool or Tractor Supply, this is wrong as
Uhaul used wheels with an odd bolt circle, 5 on 4 3/4, and a different offset than standard replacement wheels. New Uhaul rims can be purchased from Uhaul's eBay store, they are exact replacements other than the hubcap nubs.
