Wish I could help ya man. My father-in-law's truck has the same problem. Its kinda annoying but no big deal.
2001 F150 Super Crew 5.4L V8, Torsion Bars Cranked, side steps removed, K&N 77 Series intake, Pioneer DEH-P5100UB, Gryphon Programmer with one custom tune, Flowmaster SI/DO to 4 inch tips, black tails, Go Rhino Stainless Bull bar, 2 KC Daylighter Off road lights mounted to bull bar, and 16X8.5 MB 72 wheels.
The indicator is adjustable unless broken. A tiny cable is connected to the pointer, the other end is adjustable where it mounts to the column. Some have a slotted hole for adj and the later ones have a star wheel that you turn. Its a very simple thing, unless the pointer is broken, then you need to spend money.
mine done it all that it was is where the little star wheel turns was stripped so i pulled it back and put a ziptie around it and it fixed the best thing to do it find the cable its black and about a foot below the steering wheel there is a little white wheel that sets it if it is broke pull in the cable and see if the orange pointer is broke if it moves tie it back with something
yeah they are i think 6 bolts the easiest way it to take off around the steering colum the are three bolts and the pop off the piece below the spedoo and remove the bolts and and pull it off and your in
