trailer question

[BigRock44]

when is it time to change out the leaf springs in your trailer? going into my 5th year with it and they are well covered with rust. wondering at what point they should be replaced. i trailer my boat around, sometimes on the garden state pkwy at higher speeds, so wanna make sure they don't give out. any info would be greatly appreciated - thanks in advance...

I don't know the condition of your spring now but you can give fluid film a try.
Here is a link to their web site

If the springs are weak they should be replaced.
If just rusted up this could help.

U-bolts, tie-plates and axles usually rust away long before i see springs deteriorate. Fresh water rinse is a must every time your done in the salt. I use Corrosion X regular and heavy duty formula on all parts of my trailers.

Get a Float On Trailer eliminates common issues and super easy to load n unload as long as u have good water

I had leaf springs last as long as my oldest trailer 16 years.

As pointed out check of the U bolts. They will rust like hell. The leafs also have movement. So does the pivot bolt attaching them to the frame.

Get some silicone ( Not WD-40) spray in between the leafs and spray or light grease inside the pivot bolt housing on frame. If you jack up the trailer frame allowing the wheels to droop you will see how much they slide fore and aft play there is. A LOT.

Spray in between leafs to coat. The springs will take shock as good as new.
