Title: 4.0 wj big ends
Post by: supersparks on February 16, 2015, 08:10:46 PM

Hi all, my 2002 GC has had a slight tap for about 30,000 miles but now the slight tap has turned  into a very distinct big end knock, my question is if anyone has had any experience of big end bearing failure on these engines am I potentially looking at the rods going oval .And if so does anyone have a complete rod lying around.

if your anticipating oval shaped rods be prepared for wear on the crank as well

Worth fixing or just swap out the engine?
