Swap out the damaged or cracked flex plate in your 1994-1998 Dodge 5.9L Diesel. Crack or breakage can happen due to an out of balance engine/torque converter or from bolts that were not torqued to the proper specifications or in the proper sequence. Ring gear teeth can also break off or wear as a result of the starter, failure to use starter shims (where required), or engaging the starter when the engine is running. Excess noise when starting an engine can also be an indication of either a starter failure or broken or missing teeth on your flex plate. A flex plate connects the crankshaft to the torque converter. Flex plates are used on vehicles with an automatic transmission, as opposed to a flywheel that found in a manual transmission setup. Flex plates are generally much lighter and thinner than flywheels. A flex plate consists of two parts, the flex-plate and the ring gear. The flex plate can become cracked over time causing it to wobble. Symptoms of a cracked flex plate can include a clunking or grinding noise while the engine is running. Flex plates are available in OE-style steel replacements or upgraded billet versions that are SFI 29.1 certified.
