According to the manual for my 2002 Grand with the 4.0L engine, you need to use a dial bore gauge to determine piston size if replacing a piston or pistons. Getting ready to remove and tear down my 4.0L due to tapping or clacking type noise around cylinders 4, 5 or 6. Thinking maybe piston skirt but not sure. A dial bore gauge is one tool I don't have and being retired and on fixed income cash doesn't come as easy as it used to. Is there another way I can determine piston size if I do indeed need to replace one or more?
Thanks,
