Speedo

[MUDWHISTLE]

Hey guys I'm having trouble with my speedo, its rapidly flucuating when I get above 45 or so and if I'm going 65 it will swing from 65 to 45 then 50 and so on and really rapidly like it constantly is moving back and forath, I just rebuilt the reareng and replace the sensor after a wekk of driving it like this cause I figured it broke the sensor (which it did) with the new sensor it seems to swing worse. im thinking the tone ring might be messed up enough to cause this let me know please. thanks

The Tone ring is possible if you have a good sensor that is not damaged. You should be able to visually inspect the tone ring for damage. The other possibility is that your gauge cluster is dying.

Ok thanks so if the cluster is dying what do they cost and where can I get one? or can I even get one still?

call me a asz if you want, but if your speedometer worked fine before. and the only thing changed in between then and now is you all up in the rear end.......

im going to lean towards new ring.

Yeah before the diff went out it was start to just sway a mph or two and then when I got it back together it went nuts I don't really want to tear that rear end back apart but I suppose I will have to. I could just take a file to the teeth but that could take half the day and make a mess in the housing I would have to clean out so I suppose it would be better off just to replace it.

I would suggest a junk yard for a guage cluster just be sure to get a diesel one and you'll be fine. I think that the one from an late model IDI will work but I'm not positive.
