Before installing the bonded rubber bushing, make sure the Hydraulic Press - Ball Joint Assembly Tools - Spindle T10254/5 is able to fit through the hole in the inner core of the bushing. The hold drilled into the inner core of the bonded rubber bushing may prevent the Hydraulic Press - Ball Joint Assembly Tools - Spindle T10254/5 from sliding through. If this is the case, it must be drilled out.

WARNING:

Wear protective eyewear while drilling.

-- Gently pre-load the bonded rubber bushing -2- with cover horizontally in the vice clamp as illustrated -1-. Be careful not to damage the outer layer of the bonded rubber bushing.
