Speedo needle jumps up and down under around 30 mph

Hi,

Have a small problem with my speedo although it doesn't affect the running of the car, but up to about 30 mph the speedo needle jumps up and down by about 5/10 mph. Once over about 30 mph it does not do this. I think it could need a replacement cable but rather than doing this straight away wondered if it could be something else. Any ideas would be great.

Cheers
Dan

yeah i would try cable first, if its not that then its the dash! make sure you swap the circlip off the end of the old cable before you fit the gear otherwise it'll fall off into the gearbox. and take care when pullign old cable out so as not to catch the gear and pop it off

Excellent cheers John

Dan did this sort the issue I have the same problem.

Not had a chance yet, kinda bottom of the list at the moment on my things to do as it doesn't bother me too much but will let you know when I have got round to it to see if it works.

My money would be on worn diff bearings.

Don't say that. Although depends on what the bearings cost as won't cost anything to fit.

I wouldn't worry about it, mines done it since I bought her nearly 3 years ago and it hasn't afftected how it drives.

i seriously doubt it would be worn diff bearings. besides, the speedo isnt even run off the diff its run from the output shaft!

my diff bearings were very worn and the car made a nasty clunk on/off power and the flanges wobbled all over the place. but speedo was absolutely fine.
another clue that all was not well was when i drained the oil, it was metallic brown

its going to be the cable, or the clocks.

Yeah its not detrimental I agree, but for me its a niggle I want sorted….I suppose I want to get it (the car) back to near perfect which is a near impossible in some respects but thats just me.
