The simple chore of lubricating the upper control arm in my '68 got a lot harder when I snapped off the forward 90degree zerk fitting during the disconnect. Damn. It looks like my control arms (replacement) are not quite centered in my shock towers (original), making the rear zerk fitting impossible to get the grease gun on. I tried one of those rubber-hose-with-a-wire-in-it-to-open-the-zerk, but no luck there either. So, now my right control arm squeaks, but as the front zerk is broken off and the rear zerk is unaccessible, I can't lube the control arm at all. I think I'll have to pull the control arm back out to remove the broken zerk threads. Should I also "massage" the shock tower just a bit to make the rear zerk accessible? Or, is the rear zerk redundant...will pumping the front zerk fitting full push grease back the the rear part of the control arm tube? Thanks.
