Noisy Speedo.
hipichic - April 23rd, 2007 at 07:46 PM

My speedo makes the most awful noise, The speedo cable was disconnected for a while, and there was no noise at all. The cable has now been replaced and the noise is back :(
It works fine, just makes this horrid noise. Is it possible to get it repaired, or do I have to try and find a good second hand one?
Thanks!

The grease dries inside the speedo over the years, a quick fix is to get some crc in to soften the grease.Yours' is a semiauto I don't know how common the speedos for them are

Mine is a fully manual. But thanks for that, might pull it out and give the old wd40 a go.

If you remove the fuel gauge and prise the bezel of the front of the speedo, then remove the 2 screws you can remove the mechanism from the housing. Then everything is in full view, it's a bit tricky depends on how confident you are. I had to do this on my replacment speedo after the original self destructed

I'm happy enough to give it a try.... getting it out will be the hardest bit.
Thanks for the tips :)

for repair or to buy a new one??

Sorry, for repair...
They seem to be able to supply, or even make the parts.
They have repaired every one I've sent so far, mostly without problems. I doubt you'd be able to find a new one, but I've never actuaully asked anyone. I'd just get an old one properly reco'd, probably much cheaper than true new old stock... but you could ask...

Hi

Does your needle waver as well? If it does, it could be cable not sitting properly where it screws onto the back of the speedo, I've had this few times, I usually get it to go away by undoing the nut on the cable and giving the cable a wiggle.

hipichic. Disconnect the the speedo cable from the speedo, IMMEDIATELY. The speedo is about to sieze from lack of lubricant. If you leave it to squeek, it will sieze and the cable will break. That will cost you about $50.

Take the speedo out, carefully remove the back of it and squirt the internals with WD40 and a few drops of good engine oil on the moving parts. Try not to get any oil on the face of the speedo, or it will stain it.

After reassembly the speedo will read too fast, until the excess lubricant removes itself and the speedo settles down.

I agree with 1303Steve - I've had noise due to a badly fitting cable a few times too - a nasty metallic noise that sounds something like a penknife being dragged around a bean can.

What do you drive? can you reach the rear of the speedo from inside the car? If so, find an open piece of ground or a willing passenger, and simply loosen the nut and wiggle the cable at the rear of the speedo as you are driving along - you'll soon hear the difference.

If you have a bug I don't think this is possible (I'm guessing here - I never owned a bug but from memory you get access from under the hood right?). Anyhows - leave the cable loose and see if makes a difference - most of the times I have had this it is due to an overtightened nut. Definitely worth a try before ripping it out for a rebuild

A wobbling needle is simply due to a kink in the cable - As the inner cable rotates it 'whips' around causing the 'wobble' - it is possible to straighten it out if you can find the kink. (Usually it is kinked near to the ends of the cable and usually due to an over zealous or carefree mechanic) - Try near to the wheel first - if the hub has ever been taken off it is likely they left it hanging from the cable causing it to bend.

Hope this info helps.

The noise was there before the speedo cable was replaced.... disconnected it for a while, the noise was gone. Now there is a new cable and the noise is back, just as bad as before. The needle doesn't waver at all.
Thanks for the assist :)
