47-55.1 Rear Axle Problem.... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My memory for what others have done on their rigs and what has been discussed before is somewhere between slim and none. I'm thinking your rig is pretty well stock and you didn't change anything but are just freshening the suspension up with some new pieces.

What have you changed? Springs? Bushings? Axle housing? Or ??

The 4th photo down in this Jim Carter link shows a 3600 rear suspension in the "before" mode and studying it (you might have to save and enlarge it a bit) you might see something that gives you a clue. https://oldchevytrucks.com/blog/index.php/tag/34-ton/
