Inner Guards & Wheel Housings

Inner guards, wheel housings and wheel wells — the structural panels that arch over the tyres and tie outer sheet metal to the floor and aprons. For early Ford Bronco (front and rear housings, upper and lower sections), Toyota Land Cruiser 40-Series wheel wells and rear wheel assemblies, and Land Rover Defender arch structures.

The hidden failure

Wheel housings live in constant spray and packed mud, so they rot invisibly behind sound-looking outer panels. On unibody and semi-structural bodies they carry real load — a rusted housing lets quarters flex, cracks paint seams and misaligns everything above it. If your quarter panel needs steel, budget on the housing behind it needing steel too.

Installation

These are welded panels: drill factory spot welds, trial-fit with clamps, plug-weld at original locations, then seal every seam and undercoat. Weld-through primer on mating flanges is non-negotiable for longevity.

Can I replace just the lower housing section?

On Bronco housings, yes — upper and lower sections are listed separately so you only replace what's rusted.

Do housings come in pairs?

Listed individually LH/RH unless marked as a pair.
