Speedometer issues

[johnnyboxturtle]

a short time ago my speedometer stopped working properly. It isn't dead but it's not accurate. It reads over and will jump all the way up randomly. It will say I'm doing 70/80 when I'm doing about 35/40. I'm not sure what to look at or replace and I'm pretty uneasy driving in a cop thick area and never knowing my speed.

Guys,

After you lube it, can you report back and let us know if it worked.

Thanks,

The speedo gear may have teeth missing. You have to pull it out of the trans or transfer case if 4wd. Look at the color then google it. You can buy replacement gears online. 1 bolt holds it in.
It's also possible the output shaft is worn & preventing the gear from engaging to read speed.
