Can anybody tell me why my speedo isn't working? it hasn't worked since i replaced the gearbox, i've changed the cable and also had a look at the clocks but still no joy, any help would be great as its really annoying not having a speedo, cheers

 

Possibly the drive in the gearbox ??

 

take the plastic speedo drive out of the box and have a look at the teeth on it!! if its not that and every thing else is ok then its more than likely the diff bearings!
you say you changed the box but was it a new one or a 2nd hand one?

 

will be the plastic drive.there about Ł4 from ford

 

The plastic drive normally only breaks when the diff is on its way out. Sounds like a duff gearbox to me

 

gearbox was just a spare i had in the shed, it still works fine, goes in all gears and has no noises, the speedo hasn't worked for about 20k miles, (worked it out on sat nav and alot of remembering)

so i take the piece off that the speedo cable screws onto and replace it???
then see if it works? if its not that whats it likely to be??? cheers

 

the drive for the speedo going dont always mean the diff is shot.take the drive out and check to see how its worn if it is worn evenly then its just wear and tear. when i replaced mine the teeth were much smaller than the
new part so much so that i thought ford had gave me the wrong part.
not a nice job.getting the little retaining pin out can be a bastard

 

cant get the pin out, is there an easy way of doing this?

 

Been ages since I have done on in-situ, but grip it tightly with Moley's, then tap the Moley's with a hammer.

 

Sounds bloody awkward!
