Sqeaky speedometer

Eric · 02-12-2012, 07:51 PM

Have developed a sqeak in the speedo, proportionate to the road speed. My Japanese mechanic says link is electronic and solution is to replace instrument, but this requires removal of instrument panel, big and expensive job. Seems no way to inject oil into instrument.

Anyone had this problem?

This has been in the moderation queue still awaiting approval so even though I replied this thread wasn't visible.

If you let me know what year your Supra is I'll move this post to the correct forum... Might even be able to answer your question once I know more details. It sounds like dying cable for a mechanical speedo to me and while they can be lubricated they typically end up needing replacement within a year.

Dear CRE,

Thanks for the response. It's a 1987 Supra Turbo.

Ok, I've moved the thread. You want to post in the general MKIII section if you want to be sure your posts are seen.

Yes, the speedometer cable for the MKIII may be lubricated. It's a multi-piece cable with 2 or 3 segments depending on the vehicle's equipment. You may lubricate the cables with a thin motor oil, a good yet thin molybdenum oil or a PTFE liquid lubricant ('dry' teflon lubricants which apply as a liquid but then dry to leave the teflon are fine). Use a TINY funnel to pour it into each segment casing and if possible turn the cable within as you pour... It's helpful to have an assistant. You do need to remove the instrument cluster to get to the upper cable segment; I don't have the time right now to give you a write-up, hopefully someone else will step in. I recommend you do this job yourself; If your mechanic is making it sound like such a horrible job he probably doesn't want the job and if you insist he'll insist on charging you out the nose. I'd probably charge $50, maybe $60 to do it. There's also the fact that you're likely to end up replacing the cable in the next year or so now that it's making noise.

The speedometer itself is seldom the issue.
