So I just got an 88 Comanche pioneer 4.0L 2wd with the pugeot 5spd.
At low speeds >40
Speedo clicks and bumps but still reads accurate speed
At higher speeds she perfectly accurate.
Today I had zero readout on the speedo but my tripometer was still accurately spooling up. Then I hit a bump and bam she jumped to 55.
Anyone with any clue on this?
She's got 133k miles on her and I'm the third owner.
I'll look at the coupling on the tranny and see if maybe she's just wiggling loose
