Brian,

When you disassemble the hubs and knuckles you MUST check surfaces that the bearings ride on (the bore of the knuckle and the OD of
the hub). They must be true, square, and concentric. Quite often the bore of the knuckle has been elongated and is oval vertically.
The knuckles were bored with a pointed tool which results in a support area that looks like this a string of WWWWWWW's. The outer
bearing races are supported by the points of the W which "flatten out" over time. The OD of the hub can be tapered as well.

It seems to me that you might want to consider contacting Dave Lenzi and have him ship you complete hub, knuckle, and disk
assemblies with a zerk installed. You could have a local garage remove the existing assemblies from the upper and lower ball joints
which is reasonably straight forward.

Dave's hubs and knuckles are ground to make them true, square, and concentric. Material is flame sprayed on the ground surfaces and
then ground to the correct dimensions.

He supplies brake disks with four bolt holes sourced from Cinnabar which are made in the USA and are not re-drilled units from
China.

I have not used my 77 gmc elegansa mostly because the steering is so bad...I have replaced most components ordered from Dave
L.....might replace the steering box next...I have discussed steering issues with the gmcnet in the past. I have new front bearings
and seals from Jim K. I bought them a few years ago but decided not to install them as I know I am not qualified...So my
question...Me and the gmc are situated near Winnipeg Manitoba Canada...grand forks Noth Dakota 125mi. or so south...Where is the
closest place I could drive this coach to have someone qualified do front wheel bearings etc with grease fittings?..
