Rod bearing failure?

Hi,

When you replaced the bearing, did you confirm the one used was the correct size? If the crank was worn, you would have needed an oversized bearing.

Let me know.

Hi,

Since the other bearing failed, there is a good chance there is excessive wear on that journal. To determine if there is excessive clearance, you need to use a product called plastigauge.

Plastigauge looks like a string. You place it over the rod bearing and then install and torque the bearing to the manufacturer's specification. Next, you remove the end cap and you will see that the plastigauge has been crushed. Based on how crushed it is determines if there is proper clearance or if it is excessive indicating excessive wear on either the bearing or journal.

I attached a pic below showing the scales. If you have a chance, let me know what you find or if there is anything I can do to help.

Take care,

Joe

See pic below.

Hi,

The rods aren't specific to any cylinder. As long as you get one for a 3.7L and the same model year, you should be fine.

Here are two links I found that offer what you need. One is on Ebay

Let me know if that helps.

Take care,
