I have a 2001. I crawl under my truck every chance I get and grease the upper ball joints, the track bar. Look for every grease fitting you can find and just grease them until the rubber boot begins to swell. I do not believe in lifetime no lube steering joints. Unfortunately, the factory does. Be sure to lube the door opening hinges often to prevent sagging worn hinges on a quad cab. Those doors are heavy. Use a good synthetic or marine grease and you should be good. The most critical part is the track bar which has a very difficult job to do and carries alot of weight, stress. Hope this helps! Tony G
