I need some advice on leaf spring situation. Long story short, i broke a leaf spring on my dual axle boat trailer and need to replace asap before i pull anywhere else. i obviously need 4 leaf springs to replace all the way around BUT i can only find 2 -1,000 lb and 2 - 1500 lb. all are 3 leafs. is it bad for wear and tear if i put the 1500 pound leafs on one of the axles and the 1,000 pound set on the other axle? Would like to replace all 4 while I have boat off and take the time to do it, but cannot find 4 of a kind. any advice appreciated.
