They discovered my truck did already have an Okie bushing in it. The mechanic said he measured where the seal on the new bushing contacts the shaft and that is in the area where the shaft is worn. But I will pass along your suggestion to put some sealant on the outside of the Okie bushing when they install it. Tomorrow I am going on the hunt for a machine shop that can turn the shaft after I get a welder to build it up.
Thanks everyone.
