Rear gear change/speedometer correction
2003 F-250. After a rear gear change, what is required, if anything, to correct the speedometer? I’m going to a salvage yard rearend and the gear will be different. The truck had a 4.56 gear installed in it.

The speedometer signal is taken off of the ring gear on these trucks. The ring gear spins one revolution per one tire revolution, regardless of the ring gear size, so no adjustment is needed for a new gear set.
