Here is a pic of what I have talked about before. Oil weight/brand, etc wont fix a soft pin. If u look, you can see the rollers ate into the soft pin. After enough clearance , the rollers jam/break, and its all over quick. This is the same as the 3.6 issue. Its a quality issue with the pin or axle if you will. Any I have taken apart before it gets this bad, on either engine, the rollers were still mint.
