Squeaky boat trailer?

[Traxion]

I have an '04 Shorelandr galvanized trailer, roller model with a 19' boat on it. It's seemed to get more squeaky and noisy the past couple years. I checked fasteners last year and nutted/bolted everything. My old trailer's leaf springs were noisy and a coat of WD-40 every month quieted it down a lot. I tried that with this one and it wasn't the same improvement. Any hints on what to check/work on here?

Turn up the volume on the radio.

I just replaced all my leaf springs and shackles on my shoreland’r of the same vintage. They were shot. No more noise.

Mine was squeaking at the point where the leaf springs are bolted on. There was a plastic bushing in there that I replaced.

One thing you can do is replace the leaf spring mounting bolt to the shackles with a bolt that is greaseable.
