If thats the case I would guess your shocks were worn out almost a 100,000 miles ago if they are OE . I would watch for a used set of springs from a Rubicon they be a good replacement plus I see them for sale often . Some times you just have to take for granted some things need to be replaced just because of age and mileage . It may not make a major change but no one component will . Its sometimes a process of elimination . Used springs are cheap or it could be used as an excuse to add a small suspension lift .
