AX5 manual.
It's interesting that the four banger, with inherently more vibration than a six, and an AX5 transmission which is less stiff than the transmissions behind the six didn't get a harmonic balancer. The rest of the drive train is essentially the same except for minor details. The rest of the Jeep is essentially the same as well.
Thanks once again for your valuable info. I forgot that you had the 2.5 engine.
Man, I wonder if we can create a table with 4 columns (engine, trans, axle gears, balancer) and try to fill out with a poll or something. Then try to see if there is a pattern as to which combo shows a problem after regearing. That's the scientist in me asking to collect more data :risas3:
