Disco out of province inspection
We did get a Disco in for a inspection and one off the noticeable
problems was the amount of free-play in the wiper mechanism, further
inspection pointed towards wiper motor holder mounting plate,
From the factory this is a metal plate and the mount for both wiper gears is spot welded onto this plate, it turns out that this is a moisture trap, this plate was complete corroded and the top part where the mount was welded on was completely rusted out no metal left so the wiper mechanism was flopping in the wind.
We fabricated a new mounting plate out of aluminium, and grinded off the old spot welds of the bracket, painted the bracket, fitted the plate plus the original rubber seal onto the vehicle after this bolted the wiper mount onto the vehicle using the existing holes in the bracket and the studs in the fire wall, with a rubber seal between the bracket and the aluminium plate.
To make sure that the bracket was located the right way I filled in the two holes with a fender washer and used an even bigger fender washer to secure the bracket and the system works again as it left the factory.
