I've broken the front TRB setup twice, 1st time should have broke, lots of air
2nd time, little chatter, shouldn't have broke, was couple years later.
Took out locker the 1st time.
Always broke same place, broke the leading capbolt on the winged u-joint.
A stronger bolt would be nice.
Just replaced the flanges and u-joint, everything else was fine.
It was military outer tubes welded to a rockwell center, gives you 2 inch shafts thru out.
Probly shafts with the u-joint loops made right on them would be stronger.
Also on the subject of SQHD housings, ran 1 couple years with steel rear cover on
then cut of steel cover and installed aluminum one.
Kinda wonder if housing long term integrity is lost, cutting the steel cover off to save 20 lbs? If you do use the alum one, they are quite thin and easily dented.
