speedo on astra 1.7td isuzu engine

[silentriver]

ok bought probably a bad example of this car as we have another one and its great.

This one was sold to us with no brakes - dont know how it got a years MOT.

anyway - he speedo seems to say im going faster than i am actualy going.

can be in 2nd gear on a wee street and it can say im doing 40 mph.

is there any reson it would do that, or any easy way to fix it?????

ok new problem - now the back wheel seems to be wobbling...

the speedo problem normally happens when somebody has had the clocks in bits , usually for mileage correction (cough) or other legitimate reasons & hasn`t marked the position of the parts inside before removing the pointer & lost the correct tension from the little spring behind the speedo needle which throws any kind of accuracy out of the window.
