It was working one minute then quits. I can hear clicking sound behind the dash when the car is moving so it is still turning. I think the cable end is rounded. I have taken the cluster. The cable end is rounded a bit.

Can I just pull the old cable out and insert a new one in? I do not want to replace the sheath/assembly.

I prefer replacing the cable, but that is not always possible.

I have swapped the inner drive cable.
* Be sure it is an exact match, diameter, end drive shape, and length.
* Be sure it is lubricated.
* The cable nut must be fully seated to the cluster.

Note: Some older (w123 and earlier) cars have two cables passing through a cruise control speed sensor, both cables need to be lubricated and all union nuts fully seated.
