Hi there, I have a knocking sound that occurs between 1500 and 2500 rpm, I have tried to shut of one cylinder at a time and the sound is still there so it should not be any of the bearings, I have also listened with a stetoscope but can not say where the sound comes from. Any ideas what it could bee?

yes. If the rack is not held ,when you try to turn the rod you could bend the rack.With the pin out it doesn't take much to hold the rack,loosen the end with the rack "turned " so the rack is retracted into the housing,not sticking way out .

2005 chrysler 300c misfiring cylinder

I have a 2006 5.7 Hemi 300C AWD - #4 cylinder started to misfire at idle. Problem just happened without cause on a Sunday morning. Dealership mechanics have exchanges coils, PCM, etc. problem stays with #4 and is sporadic (soemtiem cold idle, sometimes hot). Happened after a new fill of 90 octane gas from Shell (always use this station, never any previous problems). Car is in perfect shape, with only the dealer ever touching it at every req. maintenance schedule. Today they are pulling the head to check for valve issues. SMART troubleshooting trees and TSB's are no help so far. Anyone else with a solution?
