Although not as important as on cars of the past, chassis greasing is still considered essential to the life and performance of your vehicle. Today, fewer areas of the chassis need the attention of grease, but those areas that do require grease should be checked and greased at least twice a year, and more often if the vehicle is operating in dust areas or under heavy-duty conditions. When greasing the chassis, use Long Life Lubricant (Ford Part No. C1AZ19590B or equivalent). Pay particular attention to your greasing. Too much grease is almost as bad as too little grease. With too much grease, road dirt is attached to the grease, and can eventually work it's way into the contact areas of many parts.
When greasing a chassis, look for areas that move frequently, like control arms, ball joints and sway bars. When you are driving, listen for squeaks and other noises from the chassis that could benefit from grease.
In addition to the areas that the manufacturer recommends greasing, there are areas of the car that should be considered for grease. For example, with the number of "aftermarket" products today, many could use grease either because of their movement, or their infrequent use. An excellent example of this point is the individuals who own snow plows. Although these are important items when it snows, many people forget to maintain them. Other examples include power winches and recreational trailers of any type. An excellent guide line to determine what to grease, is to read the manual that comes with any product having to do with your car. If you read them, you will know how to care for the product, and if it should be regularly greased.
