Got my low buck street cruiser aligned yesterday and there was a little play in the drivers side front wheel bearing I hated to just "tighten" the nut with out new grease and really didn't want to pull everything apart so I made a jack leg "slee" grease gun..... 4" of radiator hose a solid rubber plug for one end with a 3/8 hole drilled in the center for the grease gun nozzle some rubber cement and a couple hose clamps.. Works like the Slee tool except you push the radiator hose on the hub and clamp with the hose clamp.... The hose I used was a very tight fit... And pump in the grease like with the slee tool... Worked perfect .... Less than 30 min start to finish and that included building the "tool"
