Speedometer Problems

I have a 1996 Windstar GL and the speedometer is reading like 90 or so when i'm going 55 and the needle is bouncing like crazy. I need to know what the heck is wrong with this thing b4 i get a speeding ticket or something.

Sounds like the speedo gear in the trans not really hard to fix most shop can do it.Never put one in a windstar but have in others cars. It wears out over time some are plastic mostly a dealer item. But you can try napa or other parts places.

I have a 96 windstar that had similar issues. Speedo would lag behind during acceleration topping out around 35-40mph. After a shortitme it would jump up to the correct speed. Condition deteriorated over a month or so until it began erratically bouncing all over the place. Took it to a Ford garage and they removed the Speedo from the dash and sent it to a speedo repair shop for cleaning. Cost $200 becase Ford garage was the middleman. I suggest calling a speedo shop and asking them to work on it directly.
