Replace your shocks! Just did rear shocks on the 95 Jimmy (still had the orginal ones with 250K on them). Now she rides and handles like new.

 

Sway bar bushings supposedly help too... not there yet, only rolled 100,000 KM a few weeks ago, so like... 60,000 mi?

 

The previous owner did all new front end parts, front shocks, and brakes. Didn't even touch the rear of the truck??? I bought a pair of matching shocks for the rear, and double checked the rear sway bar bushing. Looks like they are newer so I didn't replace them. Don't want to put too much money into a older DD like this one.
