How to Select Replacement Leaf Springs for 5th Wheel Trailer
Question:
Im am wondering how to tell if I need to replace the leaf springs on my 32 foot 5th wheel. My rear driver side tire is wearing on the outside edges. I always keep the tires properly inflated. The bottom leaf in the spring pack on this side is twisted out of the pack by at least half an inch. I have some pictures i could send if that would help. Thanks.

It does sound like you have found some clear damage to your 5th wheel trailer's leaf springs that will require attention.
Uneven tire wear can be caused by a number of things - incorrect pressure, inadequate weight on the axle or a visibly damaged component like a leaf spring that has allowed the suspension geometry to change. It sounds like the broken driver-side spring is letting the axle hang too low on that side, which brings the tire's outside edge into more contact with the road than the inside edge of the tread surface.
As noted in the linked article on trailer maintenance leaf springs ideally will be replaced every 12K miles. I also linked our main page for replacement leaf springs. You will want to remove one spring so that you can measure its length without the weight of the trailer affecting it. You can then use the linked page to all leaf springs to select your type (slipper or double-eye), length and axle capacity.

When. You talk about 25-1/4” long leaf spring are you talking center to center or over all. And how do you measure that. I Owen a 2016 reflection by grand design 27rl and have replace all 4 leaf springs. As i replaced the they said the are stronger. But no mention of how much weight they can hold. They are still 4 leaf spring . I am wondering if i should have had 5 leaf springs instead of 4. Or is it possible. Can you use a caliper to measure the thickness. Or it does not make a difference it matters on how may leaf springs.

I have a FR Wildcat 5th wheel, 38’, 333mk, dual axle. The back tires are wearing heavily on the inside, the drivers side the most. While inspecting the undercarriage, I found the front passenger side leaf spring broken. The two front tires are wearing evenly. Are these issues related? If not what is causing the rear tires to wear so bad on the inside?
