mounts - These are basically a closed box located either side of the
car just beneath the radiator. There' s an access hole for the front bumper
bar mounting bolt on the side of these just inside the wheel well. Unfortunately
the bumper bolt access hole also provides access for sand and mud from
the wheel well and being a closed box eventually just fills up and remains
damp resulting in the rusting away of the mounts from the inside out.
By the time you see the rust coming through it's going to be bad. It isn't
even a simple case of washing out the mud as being a closed box there's
nowhere for the water to drain. Fortunately the sheetmetal work in this
area is fairly easy to reproduce and replace so anyone with metalwork
skills and a MIG welder should be able to fabricate replacement mounts
if required. You may want to consider creating a draininge hole.
the sill and bottom rear corner of the mudguard - This is a part of
the car that literally gets sandblasted by road dirt everytime you drive
the car. With time the protective underbody sealant is stripped away leaving
bare metal. As dirt and mud build up rust can eat away and open up the
front end of the sills. The bottom of the mudgard can also be eaten away
and by the time you see rust coming through to the outside a lot of damage
has already been done. The worst part however is that if the front of
your sill does open up it will begin to fill with sand and mud and eventually
result in the rusting away of part of the sill. Be wary of cars that have
body filler in this region, how much metal is left underneath???
Rear Mudgards - I've seen a number of cars with badly rusted rear
mudgards, does anyone know the reason why? Is it from leaking boot or
tailgate seals and is there's any preventative action that can be taken?
Does anyone have any further comments they'd like to add about rust trouble spots?
