I have changed all 4 springs on my unit and the shape of the new springs are exactly the same as the old ones. So I have stored the old ones for spares and will move on. The old ones were looking overloaded but this is caused by the fact that the springs are installed over the axle and the center is flat when not loaded. Its only normal that unloaded flat springs will bend once loaded. When the spring is over the axle the longer plate is not adding to the support of the plies, and to the contrary it applies pressure downward on the plies when the U-Bolts are thighten.
If the representative at Lippert would have explained that to me I would have just tighten the u-bolts and ordered 2 spare springs like I had with the previous unit. On these heavy units I found it to be neccesary to have spare springs as I need a spare tire. I can change a spring in the time it takes my wife to cook supper so I just ride with comfort.
I found that changing a top of axle spring is as easy as changing the under the axle spring units. It just took me 2 hrs to change all 4 in the campground. I never allow the nuts on the U-Bolts and shackles to rust out, and never coat it with any paint so the nuts are easier to remove.
Also you need 1 or 2 of 1/2" drive rachets with deep sockets one 7/8" and 3/4" along with 11/16 combination wrench. I use an 8 ton jack and while the truck is on the hitch I jack the whole side just enough to take the weight of the axles and then remove the springs. The hard work is if 2 springs breaks on one axle like it happened on the previous unit, then it takes the jacking of the complete axle both sides in order to line up the spring eyes in the shackles. I call a spring break when there is one or two plies broken, Most of the time its a middle ply that breaks first, but if not taken care of, it will surely break a main ply.
I had to use the truck jack to jack the spring ends to line up with the equilizer shackle, on one of the spring the last time.
