Dumb irons full of sandy mud

Scooby22 · Jan 31, 2021

A short while ago I changed my front bumper on my Defender and I was shocked at the amount of wet sandy mud that had built up in the dumb irons, the front being packed full and building up in the chassis rail, luckily my chassis is galvanized, I washed it out before fitting the new bumper.
Just thought I would bring this up incase anyone wants to check theirs and clean out this rust trap, regular cleaning may prevent theirs rusting to nothing.

A good hosing out of the chassis from both the front and the back is an essential part of the maintenance for those without a galve chassis. Preferably while it is parked at a nice angle to alow the crap indies to flush out.

I leave a garden hose in the chassis running for a good 15 minutes from each end on both main chassis rails after a good laning / offroad P&P session.

Yes, one of the many traps that require regular checking.

Whenever I wash the 90 I spend more time on the underside than the top. The top usually requires nothing more than a rinse and wash down with a good shampoo / wax solution whereas for the underside I get on my hands & knees to make sure the hose (not a pressure-washer) plays on all those places where muck (and road salt) sits.
The MOT station usually thank me for putting the 90 through nice and clean so no muck falls on their faces!

I do exactly the same, but I use a karcher pressure washer with an adjustable angle and adjustable power nozzle. Full power on all the deep grime areas abs low power on all the seal and brake type areas to wash it out.

I do it as soon as I can after playing in the mud before it dries, it’s much easier to wash out when the mud is still wet

i hang mine off the telehandler at the end of shooting season or when it has been near the cattle yard and give it the max with the steam cleaner set on hot..

more attention like the other post's on the underneath than the top especially round rear x member as mine has been patched and chassis is original..
