'96 B2300 Odometer Gone Bipolar

[Suzonda]

So I switched out the interior from a '95 B2300 4x4 to a '96 B2300 2x4, including the gauge cluster. The old odometer was basically destroyed. The new one worked for the first 14mi then stopped altogether, then after I hit a bump it started to work but it was spinning at about 3x the speed it should. I turned the key off and I heard a snap in the cluster and noticed the numbers were all over the place, then drove it again and it started working again. The speedometer is accurate and has no dead spots like the old one. Any ideas on what could cause this problem?

Welcome to TRS

Yes, common issue from 1995 to 2003 Rangers was the odometer worm gear or motor
Since speedometer works its not a speed signal issue as speedo and odo share that one signal

You can Google: Ford Ranger worm gear

Loads of info on this common issue
