Replacing the rod bearings requires mechanical knowledge and skill, a clean workspace, and several specialist tools. Our preferred procedure is to leave the engine in the car but remove the front subframe. The engine must be supported from above with an engine brace. Removing the front subframe involves disconnecting the control arms and steering rack and steering column. The oil pan can then be removed and you can access the connecting rods and bearings. Replacing the rod bearings themselves is straightforward but patience and forethought will be extremely helpful. In addition to analyzing the severity of the rod bearing wear, the crankshaft must also be inspected closely for damage. Rod bearings that have been severely worn may have damaged the crankshaft (requiring replacement or machining).
