First post on here for a while
Our boat has normally been trailered down to Cornwall for the season by now but not this year... it's still sitting on my driveway because things had degenerated further than I thought and the broken brake cable I was expecting to fix has turned into needing a whole new axle!
The trailer has an Al-ko axle and is about 8 years old. It's only done about 4,000 miles and gets dipped in salt water 4 or so times per year and gets fully flushed with fresh water every time (it's fitted with a flushing system)
The dreaded sealed bearings have never caused us any grief and in fact they still seem ok even now... it's just that everything else has crumbled!
I'm about to order a replacement axle (identical to the original so easy to fit) but I have discovered that, like the original, the suspension and brake parts are not galvanised. I am now looking at what options I have to try to make these parts last as long as possible. Obviously as the axle is permanently assembled with rubber suspension internals hot dipping is out of the question. I was thinking maybe strip the paint off the swing arms, brake backing plates and drums and painting with galvafroid or similar?
Anyone have any suggestions?
Here's what the old axle looks like... the galvanised bits are like new and the non-galvanised bits look like they are made of Cadbury's flake!
