Pop a shock off. If it goes in and out easily by hand or you see leaking around it, say bye bye.
Does the ride height look right? Are the spring cushions in decent shape? MAke sure the mount on the bottom of the differential is intact and bolted up correctly.
I like Bilstien Sports or Edelbrock IAS's but that's me. Also, if you do shocks, do all four.

If you have a cracked leaf, it is possible that your spring rate is much lower than expected, and shocks are not designed to set the ride height of the car. If you have a broken spring, the Billsteins might mask the effect, but they are not fixing the problem.
On the other hand, if your shocks are old, then I can say I just put in Billsteins and I'm glad I did ...might want to make the excuse to install them anyway.

While the leaf could still be cracked, I think the symptoms would be different.
Thanks for the heads up.

The Bilsteins or Edlebrock are Shocks. They are good replacements or upgrades over stock shocks.
However, if the rear of your car is sagging, they will not solve the problem. You will still need to replace the rear spring.

Thanks for the info on the brands of shocks. It is snowing in Michigan today. I will replace the spring and shocks before it comes out in the spring.
