Hey guys! Is there any difference between the 4.0L and the 4.2L crankshaft? I have a 1989 Jeep Wrangler Sahara that I'm in the process of rebuilding but I just found that the crankshaft is bad and I'm not sure if there is a difference in the cranks or not. If anyone can help me ASAP, Id be forever grateful!
Difference in crankshaft???
