Dave I didn't remove the large front Radius Arm bolt at the I-Beam...I did think at the time, that I would have been able to get the bushing end into the frame bracket easier if I did remove it...but was thinking that it would have changed the alignment, if the arms were not bolted onto the I-beams exactly the same angle.

240ft lbs...might need a longer breaker bar

Isn't 1/2" a bit much? When I rebuilt the front end on my '66, I made the front about 1/16' narrower than the measurement on the back side. I have no pulling,floating, etc and it tracks great.

You are right about the 1/16" on a new suspension. As they age and things get looser that number gets a little bigger to compensate. So most of us will do just fine with 1/4", 1/2" is a little excessive.

1/8" is the target, after rolling the truck back 6 feet, then forward 6 feet. 1/2" is too much, and the truck will try to "Dart" back and forth.
I always remember going for 1/16" to 1/8" as my target when setting toe in after replacing any suspension parts.

Great thread and info, thanks to all! I removed mine yesterday and will be re-assembling once the new poly bushings arrive and I replace the P-side floor pan and cab mount.

yes this forum is invaluable Chris.

So as per recommends, I torqued the bushing nut - 90. And I adjusted the toe in. I got it set to 1/8" toe in. Truck tracks and steers cleaner. And the nasty front end clunking is thing of past. Thanks so much guys.

tip: if you have a helper to read the tape measurements after each adjust, it could be easier. save lot's a crawling up and down...if you have a reliable tape reader.
