Should steel cables in two-post lifts be lubricated?
In most cases you don't need to lubricate the steel cables in a two-post lift. If the cables work in dry conditions, with no standing water under the channel, they last up to 15 years with no maintenance at all. Lubrication only makes sense when the lift is connected at the bottom and the cables are in constant contact with moisture — and in that case you use a penetrating wire-rope lubricant, not ordinary machine grease.
