Question:
I think I need New leaf springs. The last 3 trips I get side to side rolling and then sway. I have a 2021 37 ft fifth wheel 336tsik with about 11,000 miles on it. I have the blue road armor and have replaced the wet bolts and bushings with no change in handling. I have a 2021 ram 2500 as my tow vehicle. Now the confusing part, when I measure the springs I get center to center of 25 1/4 to 25 3/4 unloaded on the four springs. I have Dexter 5100 lb axel 7834479 and plan to upgrade spring weight capacity. Any help is appreciated.
