My wagon is starting to lean a bit on the right and I figure its time for springs and/ or shocks. Anyone have a good recommendation for replacements? I want to either keep the ride height the same, or even get the rear a bit higher but not too much. Rock auto has only one "wagon" spring in their catalog, but there are plenty of shocks. I was considering the: Monroe # 58574 Sensa-Trac Load Adjusting Shock Absorber; Maintains Ride Height Up To 1200 lbs.; Package of Two -are these decent? I also have air ride and would have just replaced the air shocks, but no idea if the compressor works as it was unplugged and the plug contacts are all oxidized and green.
