Hi guys.

I know the rear axle/ springs need a yearly treatment of oil/wax/paint, anywhere else advisable while I'm under there! :slayer:

Rear drums are a good shout if fitted. They look very scabby after a short while.

Also the tops of the rear struts came get a pile of crud up there if it's been anywhere near mud, clean out and a shot of oil is a good idea.

So here's what I've done

Painted the bottom of the spring cups with underseal

Sprayed the backing plates of the rear brakes and drums with one thin coat of stone chip, also sprayed the springs with one coat of stone chip

Made a home mix of gear oil and thinners to spray inside the spring cups.

All the above done after an attempt to get the road dirt off said items, but it was pretty ingrained on them.

Repeat next year?

Hi.
The only thing I'd not use is underseal, it can get water trapped behind it and actually make things worse.
Make sure there is no rust initially and if so clean it off with a wire brush, then use Bilt Hamber De-oxit rust converter, either use their wax spray or Waxoyl. Keep the beam clean, even a wash with a garden hose is enough, make sure the holes in the cups are not blocked with grit or even wax as these need to drain.
After that a check each year and re-application of the wax if necessary will be fine.

There was no rust just road debris
