AERA Members have reported a front end engine rattle noise on 1999-2009 Ford 4.0L SOHC engines. This noise is audible during hot and cold conditions, but is most commonly heard when the engine is cold under acceleration at 2400-2500 RPM.
To confirm the presence of this noise, put the vehicle in 2nd gear and accelerate the engine between 2000-3000 RPM and listen for a rattle noise that sounds similar to a spark knock. This type of rattle noise could be cause by the primary timing chain tensioner system.
Ford advises that the primary timing chain tensioner, chain guide, jackshaft and crankshaft sprockets be replaced with a correct repair kit. The kit will include all parts listed previously along with required fasteners, primary timing chain and front cover gaskets.
There are two kits offered to cure this problem. One kit is for an engine that has a balance shaft and the other kit is for an engine without a balance shaft. When ordering the replacement kit, make sure that the correct kit is ordered for your application.
