No, on a 1 legger rearend, you must spin the tire two times. You must double it. For instance, you spin the tire twice, you will find the pinion spins 3.73 turns.

Or, you can buy 2 quarts of lube, a tube of silicone, and a can of crab spray cleaner and do it right. Who knows how old and nasty the fluid in there is. You don't want you bearings running in dirty grease do you ? Do it right. It won't take 15 minutes.
