When the engine in an old sports utility vehicle (SUV) started knocking, the owner answered with an engine teardown. The source of the knock, some worn-out bearings between the connecting rods and the crankshaft, could be fixed. The project needed new parts, the right tools, and some automotive know-how.
The SUV’s owner, a former auto mechanic, bought a remanufactured crankshaft from a local auto parts store. The crankshaft came with journal bearings, but required removing the cylinder heads and pistons. So the owner of the 1999 GMC Jimmy bought some new piston rings and engine gaskets, too.
To hone the engine’s cylinders, the mechanic used the BRM Flex-Hone® tool.
