The 82 Hatchback Problem

Yes, the hatchback is handy and looks cool - when it actually operates. The problem is that after 20 plus years, most will not function.

Cause and Effect

Apparently the metal arms that are part of the hinge mechanism tend to shift after a while. Some say this is due to the rearward pressure applied by the hatch pistons in their closed position. This causes the hatchback glass to shift toward the rear of the car, which causes the roof release pins to bind rather than release. In addition, this leaves a gap at the highest point where the hatchback meets the roof, which the rubber lining cannot seal. This leads to leaking, no actually flooding in wet weather.

The quick solution

First the quick fix which will allow you to drive in the rain and wash the car without soaking the interior.

You need a length of small plastic hose. This type of flexible tubing can be found at some hardware stores or most aquarium shops. The size you buy depends on the size of your particular gap. Slip the tubing into the fold of the rubber gasket. This will expand the rubber to fill the gap. Simple, eh? Probably the least expensive thing you will ever do to your Shark.

 

A disciplined, ergonomic environment, but there's a tangible luxury and a hatch that lifts to the aroma of fine leather.
