Hello Everyone, I have bought a 03 3.7 Liberty here in the UK. The Jeep has a knocking crankshaft so I got it cheap. However I cannot find out the crankshaft journal sizes, tolerances or available undersize bearings etc. I have a Haynes manual but no info. My local machine shops here in the UK do not have this information. I would be very grateful if any of you could help me out. Thank you. |
