How To Replace F150 Shocks

I seemed to notice my truck not handle as well in the recent months. My shocks weren’t leaking… they were just wore out!!! If you notice your truck seems to ride sloppy or not have as tight handling or seems to have a lot of nose dive when breaking, it's time to replace your shocks.

Easiest way to check the shocks are the bounce test. Push down on each bumper with force and see how well it rebounds. If it takes awhile to rebound or bounces a few times then they are worn. Shock manufacturers recommend replacement at about 50,000 mile or 80,000 kilometer intervals.

This article is for a 1998 F-150 2WD. However it applies to 1997-2003 and 2004 heritage trucks. The process is the same, the tools may differ.

This job is pretty easy. It takes a lot of patience especially on the rear shocks. There’s not much room to work with. I replaced these shocks along with my idler arm in 2 hours. Granted I am a professional…but expect no more than 2-3 hours even with rust problems.

Shocks Replacement

NOTE: If you run into a problem with the nuts on the shock stud not coming off the top studs, you can use a sawzall and carefully cut through the nut and stud going through the rubber bushing carefully. Check that your new shocks come with new bushings and hardware… my Monroes did. I however did not have to cut anything. The top stud on the left front shock snapped upon removal. You may get lucky
