Wait time for a rear axle assembly for a 2017 Jeep Wrangler Sport Unlimited.

Hello,

I'm a first time Jeep Owner, I bought a slightly used 2017 Jeep Wrangler Sport S unlimited a little over 2 years ago. From that time forward, I made upgrades to my Jeep including a 3" lift and 35" tires.
About 4 weeks ago while driving my Jeep through normal city traffic, my jeep made this loud "thunk" noise, then it wouldn't move. I had to call a tow truck to have my jeep towed back to the dealership. When they looked over my Jeep, they told me that the rear axle assembly needs to be replaced. With everything going (Covid disrupting supply chain) how long can I expect to wait before the dealership can get a replacement rear axle assembly? This is a warranty covered repair as this happened at under 55,000 miles, along with the fact that I bought an extended warranty for my Jeep. Does anyone know how long of a lead time there is for axle assemblies? Are we talking weeks ? Or Months ? Thank you !

Take your VIN#, call a different dealership's parts department. Ask them to look up the axle assemble and give you price and availability (P&A). That'll be the best answer you'll get.
All anyone here could possibly do is guess, especially since there are a bunch of different axle assemblies possible. Some may be more available than others. Your VIN# will get the correct part looked up. Unless you re-geared your axles when you went to larger tires...

Oh....I spent many years in Jeeps parts departments. I've seen axle assemblies come out of the local warehouse the next day. I've also seen them on backorder and take months.
So yea, only a dealership with access to the inventory system can even start to give you an accurate estimate.

I've have done already.. Originally they told me 1-2 weeks.. now it's been 4 weeks, and the latest news the dealership gave me is they expect to have a rear axle assembly by Mid-September !

You don't need a 'rear axle assembly', you just need the part that broke inside. If you weren't waiting for it being free warranty work, you'd likely be driving it already.

Hello all, Just a quick update on my rear axle; the Dealership finally located a stock Dana 44 Rear axle out on the west coast somewhere.
They said it would take approximately 10 days to arrive. My next question is: Can a stock Dana 44 rear axle with stock gearing safely handle 35 inch tires ? Thanks for the help !

That should have been the first question. What exactly is the stock gearing?

Yea, "stock" gearing means nothing. There were several "stock" gear ratios available, depending on the options the Jeeps was built with.
Another thing to make sure of is that the gear ratio matches the front axle, or you will destroy something the first time you put it into 4wd.
Were your axles re-geared when the lift/tires were done? If so, the new one almost certainly won't match the front.

depending on what Jk it came out of could be 3.21, 3.73 or 4.1. But you NEED one that matches the front ratio. d44 can roll 35s easy. The issue you had i bet it had LSD, known to fail. on stock tires.

Your jeep unless it has max tow is 3.21< not enough gear for 35s. If you had a Rubicon auto with the 4.1 stock it could do the 35s. But target is more like 4.56 on 35s<street.

I agree a shop would have set a new carrier and even gears and bearings been done in a day....... heck i have a friend that would do it for 250 labor, your parts.

This goes back to my post 5 above. Fix what's broken, don't just swap the axle because it's in you garage skill comfort zone.

From what the dealership told me, my jeep is geared at 3.21 with a limited slip differential.. As I mentioned before I am a first time Jeep Owner, so I'm beginning to realize that there are many drivetrain options available.

Once I have my Jeep back, that will be one of the questions I ask them; do both front and rear axles match each other ?

I would be asking that question BEFORE you get your Jeep back.

I don't like to "assume" anything, however it would seem that in my case, both front and rear axles are geared to 3.21. Are there known cases where this is not always true ?
As I mentioned previously I bought it as a "Stock" Sport unlimited (JKU).
