I just got off the phone with the toyota dealer support....?? ?? ?? donīt know what you guyīs call it over there...
anyhow. he told me that the diesel and bensin trucks have the same flywheel. At least he looked at. the landcruiser and from 1.august ī98 - sept 2002 the bensin models = kzj and the diesel models =kdj had the same flywheel. and he told me that he was 90% sure that the 4runner had the same deal. (he couldnīt find info about the runner but same engines should mean the same deal)
I hope this info is correct and that it helps you.... the only other way for me to find that info would be at the junk yard and he only has engines sitting in trucks.
