I've just converted a car from standard to HD ballcups and tried running a dribble of graphite lube (its actually lock lubricant) into each cup before i threaded the turnbuckle in.
It was possible to run the turnbuckle all the way into the new cup (and cut the thread) just using fingers. The one or two i tested were easy to adjust, no popping off at all. Now the carrier has evaporated/dried, they still adjust fine (no popping), but no longer adjustable by hand! Need a turnbuckle spanner. (as it should do)
For the ones i finally ended up fitting to the car, I also heated the HD cups up (hot water) before i popped them on, they were easier to fit, and once cooled, a much tighter fit than the ones i tried doing with the cups at room temperature. At least, they are significantly harder to pop off.
I'm actually running another car with the Associated/RPM mod. as well.
Will see how the "all the tweaks" car compares to the "give up and use someone else's parts" car, once i've had a chance to them both.
