speedo problem
well it work's sometimes and sometimes it don't.It's a 92 f350 with rear abs.Ithought it worked off the rear end RABS sensor and a box under the dash.I was at a local parts store the other day picking up some things and asked about the sensors while there.And the manger said that on my truck he thought it worked of the one on the transfer case or transmission and some components under the hood.anyway i have a 5spd trans i'm pretty sure it opperates on the RABS 1 system. any incite would be greatfull

If your truck has a mechanical odometer then the whole mechanism.. speedo and ODO are cable driven off the trans or transfer case, but if it has an LCD odometer the whole speedo assembly is electronically driven from a PSOM module via the RABS/VSS sensor on the rear axle
