Reason I ask is my 2005 F-150 Supercrew is making some sounds over dips that I suspect to be suspension related. It got me to thinking how long can you expect shocks to last on a truck. I only have 62K miles on it but what is the typical longevity for shocks? What brands would make good replacements? My truck is 2WD so I don't need anything off-roading rated.
