Hi all, I have just joined the forum and need some repair advise. i am suspecting i have a problem with a rod bearing. a while ago a my 3.5 startech 300c suddenly developed a knocking noise. i have been doing a lttle research and suspect it could be a rod bearing after listening to various youtube footage. i am by no means a car mechanic but have done various repairs and replaced engine parts on the car but not the suspect bearings . any advise would be appreciated . cheers.
