Dear John and Paulli,

Thank you for your responses. You have answered my question so well that it even addressed the part I failed to state in my post. Yes! the speedometer has stopped working on two occasions. So if you would be kind enough to indulge a further question; which part should I change first, the differential sending unit or the wheel sensors starting with the passenger side?

This Brickboard (meaning posters like you guys) are such a pleasure to correspond with that I almost don't mind buying the parts. I'm going to price them out right now.

Double thanks to you both,

Len K.
