We just purchased a used 2006 Grand Surveyor GS272. The previous owner said the bearings would need to be packed (he had them done in 2011). I am a do-it-yourself person and am having trouble finding information on how to grease the bearings. Part of the problem is I do not know what type of axles I have. I have read some information on here about just being able to hook up a grease gun to zerk fittings and other information about pulling the bearings out. Just trying to save the $230 I would have to pay to have someone else do it.
