I personally would just put it down to primitive mechanical instruments, that are 14-20 years old
Ive seen it on allsorts of makes/models of cars, it usually only wobbles within a certain speed, and is fine when below or above it

A wobbly needle can onyl really be caused by a worn instrument or a fluctuating output on the speedo drive. Hence why i can't see a leaky seal doing it.
Were you talking about the driveshaft oil seals?

Usually, when the diff bearings wear out, the diff starts to move in directions it's not meant to. This will wear out the shaft oil seals and the plastic (red) speedo drive gear.
The speedo drive ger can be pulled out easily, so it's best to check tht first. If it's gone to a concave shape, then the bearings have definately gone.

Always found a wobbly speedo was due to one thing on Fords, lack of grease on the end which plugs into the back of the clocks. Take it out and grease it, replace it and it's should work perfectly.
