CONTROL ARM UPGRADE
The 3 bearing modification never
became a universal standard because it is very hard to keep a 3 point
alignment of the bearings during machining and later versions of this
modifications of this design were never of the same quality of
the Wallace components and the bearings became hard to find and
As a part of his design, Wallace developed a greasing procedure that allowed the bearings to be serviced without removing the hub knuckle, bearing components.
Dave Lenzi, one of our modern GMC heroes, has been rebuilding and providing hubs and knuckles with the Zerk and bearings with a modified bearing spacer that is allowing bearings to last in the area of 100,000 miles with 30,000 mile (non removal ) bearing service.
GET THE ZERK ON YOUR GMC
1 At your next bearing service if you find damaged hubs and knuckles, send them to Dave Lenzi or his supported vendors, to get them rebuilt and drilled for the Zerk.
2 Drill your own knuckles using this procedure from Ray Swartzendruber
