Speedometer adjustment?

[Evan93]

I have been driving my festiva with 13" wheels for a few months now knowing that the speed isnt accurate anymore but I was wondering if there is an easy/cheap way to adjust it for the new wheels. Luckily I know about how far off it is so it doesn't bother me much. Also the needle shakes quite a bit, other than buying a new cluster guage is there a fix for that? Again it doesnt bother me much so I prob wont do anything about it for awhile, but I thought I should find out what would be involved.

Ya thanks, I had seen that before I put the wheels on, it definately helped.

Evan93, it sounds like you may need to lubricate your speedometer cable. That can be one of the tell-tale signs of a cable going bad. My Aspire speedo did that, and when I lubed it up, all the problems were gone.

Definitely luber up good. An Aspire has to have a different gear or cluster to
correct for 13 tires. One of those parts may work, hopefully someone who
has done this will chime in.

Ok so today after looking up how best to lubricate my speedometer cable I went for it today. I used a white lithium grease. Good news was that I was able to get it all apart and back together, speedometer still working, unfortunately the needle still shakes. I'm gonna take another go at it tomorrow. Should I be using a lot of grease? I have also heard to use a powder graphite? Any advice or other things to try?

you need to look at the speedo unit itself... that lythium is 20 years old and proly dried out.

Cluster may be different, but the speedo housing and gear are identical on the manual transmissions.

Found a kink in the cable today. Looking for a new one, o'reillys can special order one wont be here for a week or 2 for about $30. Autozone has universial speedometer cable kit for under $10. And none of the nearby junkyards have any festivas. Anyone used the universal kits? Or should I just order a whole new one, from o'reillys?
