Hi,

That sounds a little low in mileage to be losing a suspension spring on a vehicle that is considered to be a Cross Country one!

You kept this vehicle in a garage and not outside on a pile of rocky hillside!
For Jeeps that’s a normal life!
There was one year in particular that Chrysler warranted the drive train for the life of the original owner.
They didn’t do that anymore!
Every time she, my neighbor, takes it in for a service, they would like for her to trade it in!

Was there any kind of service bulletins or recalls issued?
It can be very easy to make defective springs as its tricky metallurgy!
Each one is made and checked to meet within a specification range and can be batched or matched accordingly for strength range.
I can only see this happening if there were two different part numbers for left and right.
Doubtful for inventory reasons, but Research might be warranted out of curiosity!

Durability can always be unknown unless there was a run of bad ones!
That doesn’t mean the other one, will or won’t suffer the same fate, as it depends on so many other factors!

The XC part opens up another realm of paperwork clauses and the fine print therein?
In days before paper, “Is it worth the fabric it’s printed on!”
Not much has changed except it’s a virtual screen, “Is it worth the power to light it up?”

Another question would be, Are you the original owner! ?????
If so, You might have some complaint but with the same results!

“KlausC” has the right idea, There are other options!
“Keeping it running is better than buying NEW!”
