another radius arm bushing question

[bushman_22]

I am changing my c bushings in my 73. I disassembled, cleaned and painted everything. Prelubed everything with plenty of energy suspension lube. I am installing Duff poly bushings. I have them started and have been tightening them down slow and even. Is the torque for the poly bushings going to be more that the factory cap torque? What is it? Or do I keep going until the caps seat to the arms? And yes I have the bushings in the correct orientation.

Thanks

You want to keep going til the cap meets the arms. I did mine to 100 ft lbs.

Yep, factory torque. Nothing is supposed to have changed there, due to the two steel surfaces meeting in the middle.
Are you wondering because some of that nice new blue polyurethane is getting squeezed out the sides as you keep turning the bolts down by any chance?
If so, unfortunately, that's become the norm. And, other than making it harder to start the bolts and putting more of a squeeze on things, it's not really hurting anything. Be interesting to see if it's creating more resistance to wheel travel, but I don't know anyone who's tested for that.

The first set I ever installed did not do that, but in the last twenty or so years, it appears to just be getting worse and worse. At least with the other brands. Don't remember who makes Duff's bushings, or if they do it themselves, but most are going to sqeeze out to some extent.
Maybe the old molds are still being used and they're wearing out? Don't know if poly molds wear, but if not, then they're making them too big on purpose for some reason.

If that's not what you were wondering, just ignore this post. :-[
