Some 1985, 1986, and 1987 C/K and R/V model trucks may experience a noisy or inoperative speedometer. This condition may be caused by the
speedometer cable contacting the engine exhaust between the cable connection on the transmission or transfer case and the first cable clamp located on
the floor pan. If the contact occurs, the high exhaust temperature may damage the speedometer cable.

A new design speedometer cable has been released to repair this condition when found (See Figure No. 1 for K/V models, Figure No. 2 for C/R models).
