Thinking about rebuilding the rear suspension in my 75.

I'm looking at the PST polyurethane setup. Anybody know if it is any good?

Second of all, is it hard to do? This will be my first suspension job, and I am not sure exactly how much work/down time is involved.

And lastly, my rear leaf spring looks like it's falling to pieces. Should I replace it with a kool monospring (~360 lbs.)? If so, where can I get a good deal in one?

Thanks alot:(

i'm doing mine as a winter project. removing the differential was fairly easy. rebuilding it requires some special tools. fortunately i have a GM dealer tech helping me do mine.

i did my own wheel bearings about 3 years ago. the worst part is the removal os the components. by now most nuts and bolts are really rusted. but, with some good penetrating oil and some heat ( i've even used a propane torch) they will break free.

here are two links that may help you out. as far as the parts go, all i can say is shop on-line for the best price to match quality.

also, you need to decide what you want to do back there. new strut rods? then, what kind. rubber or poly bushings? i've read pros and cons for using both.

a mono spring will run about 300-400 bucks. but, again, shop around on-line for a price.

I'm in process of build-up on my rear susp and drivetrain. It started with wanting to replace the rear bearings and bushings, and turned into a 'while I'm there' project. That's another story.
I didn't go with a peticular bushing 'kit' per say, as I wanted specific replacement parts such as offset T/A's, which came with poly bush's. And I chose the adjustable struts, which also came with poly bush's installed. The only place I didn't use a poly bush was where the susp and driveline connected to the body. I chose to stay with rubber for this.
As for the spring, I replaced my 9 leaf steel with a 315 lb mono glass. I don't plan on any serious track racing, and want a decent ride on the street.
I also replaced my own rear bearings and spindles. To me, this was the 'fun' stuff!
This can be alot of work, depending on your ability and shop setup. As with any older vehicle, it's a matter of learning to deal with rusted fasteners and corroded parts. Having the correct tools to accomplish this will help cut the time/headaches involved.
I found myself purchasing/building some additional tools to 'rip' into this project.
Do all your reading and research first, as this will better equip you for the attack!
Feel free to email me if you need help, or have any questions. As I don't visit the forum too often.
Here's a couple other links that may help:

good links, rod nock....

i forgot to mention...while you're at it back there and you have the wheel bearings apart, buy some stainless steel e-brakes and install them BEFORE you put the spindles back on.

attempting to do this with the spindles on will tax the patience of even the best of mechanics.

By rebuilding the rear suspension are you just talking about replacing the spring and the hanger cushions or like some are suggesting doing the trailing arms, the bearings and the rearend.
If it is just the spring and hangers it is easy, an evening but the trailing arm bushings and rear bearings are weeks for a novice to do and alot of problems.
