It won't be a cable, as it's impossible for a cable driven speedo to perform this way.
It's an electronic speedo.

Check and/or replace the speedo sensor in the gearbox housing.

I have an '86 Runner myself, most likely the cause will be blown shocks. I would also check the wheel bearing play and the ball-joints at the top and bottom of the steering knuckles. The broken C.V. boots don't usually cause a tire type bounce, more of a consistent vibration that varies at different speeds. And the shocks are pretty the only real DIY item on that list, everything else should be done by someone with experience, preferably Toyota experience.


I hope this info helps!

It has regular shocks on the front.

Is it a bounce or a vibration. If it where the struts you would only feel it when you went over a bump. To me it sounds like you have a tire issue. Either a tire is seperated or maybe out of balance. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

Did anyone inspect the shock absorbers? Run the tires at the lower air pressure limit unless you are hauling heavy loads. Have the rear wheel alignment checked--it could have a bent axle housing. Check the rear universal joint and drive line for any damage. Did the truck, when new, have this problem? Is there any strange noise occurring when this happens? Hope some of this helps!
