Shaking mirrors (1988 80)

[tnas@dtpdirect.nl (Tom Nas, DTP Direct bv)]

Hi all,

The righthand door mirror om my 1988 80 is shaking when I drive. Extremely
irritating, and it renders the thing almost useless. The lefthand one is
(luckily) steady as a rock.
It doesn't *seem* loose on its mountings, so what else can it be?

Any ideas anyone? Or just 'yeah, mine does that too'?

TIA!

Bye,

Tom.

  "That depends a good deal on where you want to get to," said the cat.
