1984 speedometer jumping

this is driving me nuts, the car is in otherwise great shape, but the "ticking" speedo ruins it for me. I replaced the speedo cable, but it just got worse. This is an old style "three dial" dash. What's the best two ways to handle this one.

regards, P

I tug on the cable and it seems to go away, temporarily. I loosened the instrument cluster and pulled it out slightly and it seemed to help a bit, I think there is some lateral pressure on the gear due to the cable coming in on an angle, but the gear may be shot now, as the car has 160,000 on the odometer.

The steering wheel has to come off to get the instrument cluster out, so I'm wondering what the good fix is. Can I just replace a gear, or do I need to send the unit in to a specialist, or just buy a new one. The old style Porsche 944 speedometer may be the same as the one used on the Audi of the same vintage, or perhaps a VW, dunno.

He put a new cable in.

The cable should extend through the grease cap on the hub and have a surclip. If it doesn't then the other end of the cable sticks out too far and will put pressure on the speedo gears. This will also happen if the square end of the cable is not seated correctly in the speedo or if there is some debrie in the speedo reciever.

I've seen a few cases where the speedo end of the cable had to be shortened.

I agree with so cal. The end of the cable in the front hub is probley not seated correctly. If you want to try a different speedo, I have a couple of extra that I know are good. That way you will know if it is the speedo or the cable. E-mail me if you want

Guys, many thanks for the tips, SoCal and Todd, thanks greatly. Todd, I may take you up on the speedo, I'll check the cable routing, etc., as soon as it warms up (going to be a "hard freeze" here in Tennessee tonight, but will warm up again next week.
