Just swap it all out with the factory stuff every 5 years before the inspection.

 

So doing axle mods voids the engine warranty?

 

The last section below is the only List of Modifications that will Void the Warranty.....Other Modifications DO NOT,by themselves, VOID the Warranties.

This is Easy and Fast to Look up.... Jeep.com.....Top left, Owners...drop down to Warranties....Enter 2008 or Older Cause 2009 doesn't have and will not show the Lifetime Warranty Book, check the box that you purchased before or after the date they have listed

3. What's Not Covered
3.1 Modifications Not Covered


A. Some Modifications Don’t Void the
Warranties But Aren’t Covered
Certain changes that you might make to your
vehicle do not, by themselves, void the warranties
described in this booklet. Examples of some of
these changes are:

Performance or racing parts are considered to be
non-Chrysler parts. Repairs or adjustments caused
by their use are not covered under your warranties.

Examples of the types of alterations not covered are:
• installing accessories — except for genuine
Chrysler / MOPAR accessories installed by
an authorized Chrysler, Dodge or Jeep dealer;

B. Modifications That WILL Void Your
Warranties
These actions will void your warranties:
• disconnecting, tampering with, or altering the
odometer will void your warranties, unless your
repairing technician follows the legal requirements
for repairing or replacing odometers; or
• attaching any device that disconnects the
odometer will also void your warranties.

 

In Short...No

 

That's what I thought. I'll have to show them that information when I go back in.

 

Those axles are components of the power train that's being covered. If you modify them you change the original architecture of the vehicle. Your 4x4 system is part of your power train. As I said before a non stock oil pan will cause you to fail the inspection. If you need to modify the axles because of your driving needs, you're going outside the vehicles original manufactured capabilities. Why would you risk it?

 

And I'm just playing devils advocate BTW.

 

I have always thought the 2009 also had the lifetime powertrain warranty, so I looked it up as you directed.

2009 has it. Mine does.

 

Put a snowplow on and you can kiss your warranty good bye also.
