When off warranty and/or fixing axle area problems, I alway +1 "up size" its leaf springs packs. And where possible, upgrade the axle as well. For example, replace factory 3.,000 lbs axle with mew 3,600 lbs axle. And, upgrade with 3,600 lbs leaf spring packs as well.
Remember that many trailer makers subtract 13% off the Trailer's GVW number (assume 13% weight is on the Tow Vehicle's hitch), then divide remaining number by the number of axles. On the "white board", it appears the smaller axle / small leaf spring packs are the correct size. And, save RV maker parts money. Maybe true for some lawyers as well. But IMO (being a certified Engineer), the factory axle and leaf spring packs are "under sized" for the trailer's GVW number. Thus, why I always "up size" without using the 13% Tow Vehicle hitch weight number.
Like I always tell my wife and others... Better to be over engineered / over safe instead of at minimum factory build specs (and risk leaf spring pack breaks across double railway tracks). But, that's a topic for a different post....
