Anyone know the correct stock dimension between the rear axle and the bump-stop on the frame? Mine is around 3-1/2" (not the same on both sides of course). With a load in the bed and towing a trailer (but far from GCVW) the bump makes contact regularly. I guess it's ok with me if that's normal, but it makes the ride a little rough. I was just thinking that maybe the springs are getting flat since it's now 8yrs old. Is their a different dimension I should check, or how else do I know if the springs are flat? There's about 1/2-3/4" between the springs and the overload if that helps anyone. I don't tow/haul a whole lot, but the PO was a travel trailer hauler.
