Toyota Land Cruiser 70: Windscreen-surround and A-pillar rust on coastal, beach and gravel-road vehicles

The windscreen surround and the A-pillars either side of it are the 70 Series' worst rust spot. Water sits in the bottom corners of the screen aperture and creeps under the rubber, and the factory paint and sealing in that channel was never up to salt air, so coastal, beach and ex-mine vehicles rot there first. It is made much worse by a windscreen that has been replaced badly, because a poor refit traps water against bare metal and the rust then works outwards from under the rubber where nobody can see it. What starts as a line of bubbled paint ends as holes in a structural pillar, water running down the inside of the cabin, and a screen that cannot be safely re-bonded. Repair ranges from cutting out and re-welding one bottom corner to replacing both pillars, which is the sort of bill that writes off an otherwise sound truck.

• Bubbled, crazed or lifting paint along the edge of the windscreen rubber
• A brown stain seeping out from under the windscreen rubber, worst in the bottom corners
• Damp or stained headlining at the top corners, or a musty smell in the cabin
• Water on the floor or in the footwell after rain
• A rippled or wavy edge where the pillar should be dead straight

1. 1

   Stand at the front corner of the vehicle and run a fingertip slowly along the painted lip where the windscreen rubber meets the pillar, from the bottom corner all the way up to the roof, on both sides.

2. 2

   Feel and look for paint that has bubbled, crazed or lifted, for a brown line seeping out from beneath the rubber, and for any place where the metal edge feels rippled rather than dead straight.

3. 3

   Press gently on any bubble with your thumb, because sound metal stays firm while rust that has eaten through feels soft or crunches.

4. 4

   Look hardest at the two bottom corners of the screen where water pools, and at the base of the pillar where it meets the sill and the door hinge.

5. 5

   Open the door and check the pillar from the inside, then sit in the driver's seat on a bright day and look up at the corners of the headlining and along the top of the dash for water staining, mould or a musty smell.

6. 6

   Ask whether the windscreen has ever been replaced, who did it and whether rust was treated at the time, because a badly refitted screen is the usual start of this.

7. 7

   Ask where the vehicle has lived and worked, since coastal, beach and mining vehicles are far worse than inland ones.

8. 8

   If a workshop inspection is possible: ask a panel shop to sound out the pillar and look behind the rubber and the scuttle panel, because the visible bubble is normally the small end of it.

$1,200 to $16,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “Has the windscreen ever been replaced, and by whom?”
• “Was any rust treated when the screen was out, and is there an invoice?”
• “Where has the vehicle lived — how close to the coast, and has it been driven on beaches?”
• “Has it ever leaked water into the cabin?”
• “Has any rust repair or panel work been done to the pillars or the roof?”
