Which cable seizes? Is it the one from the dash to the splitter, or one of the wheel cables?
Generally, the inner sheath rusts and damages the plastic coating on the cable, which makes it jam. No amount of lube down the sheath will free them up.
I know it's pretty obvious, but if you can work out which cable it is; there are companies that can manufacture factory style, plastic coated inner wire replacement cables.
I'm sure Nissan replacement cables will be fairly pricey.
