I'm having major issues attaching the rear LST diff to my traxxas CVD centre drive shaft.
Originally I used the LST coupling and put a pin through the coupling and CVD, plus a washer either side to take the slop out and held the pin in with heat shrink.
But the heat shrink gets worn away really quickly, the pin falls out and wears a groove through the plastic surrounding and the drive shaft, being no longer connected to the rear diff, means the rear wheels stop driving. This had happened a few times already and I fixed it again this morning, but today it only lasted 30mins before it happened again and I lost rear drive again!
So how do I attach the centre drive shaft to the LST diffs so that the pin can't come out?????
Bash it like someone else has to fix it!
