They did both at the same time on mine

And believe or not, there are dealerships that don't know it.....the first one they did on mine,they didn't realize.....took another week for a new PTU and a module to arrive.
Funny thing is, I know for a fact the same dealer had replaced a PTU (properly) on my friend's Cherokee many months previous.

Got my TH back on Friday. No one to talk to when I picked it up....this was the paperwork. As I understand from a prior call, they had to put in a 2nd PTU (first replacementt was bad), guts for the rearend, and a rear driveline.

Went in and talked to my service mgr. I got confirmation to my thoughts and interpreted info. Going by codes, PTU needed replacement. Put it in and test drove it. "Horrible" grinding from rear end. New PTU was bad from factory. They had to do a little convincing to "Star," about receiving bad parts, but came through. Checked rear end and fluid was silver/grey from metal shavings/dust. Replaced guts and driveline. Supposedly better! Time will tell. Kinda scared now. Trusted my vehicle unconditionally. Now leery. What is the name of the best place to get extended protection plans??? Interested in lifetime now....

What are your thoughts on drivetrain break-in?

Actually in my opinion for any drive-train replacement/repair part regarding break in, I would follow the original 300 mile one that came with the vehicle.
Personally I would go a little longer as I did when my vehicle was "new". If towing, especially as that puts extra stress/heat on the parts, I would follow the tow break in guide (500 miles) also.
If the trailer is upper end on weight I still would extent that 500 miles out a little longer. I once lost the rear differential on my 2001 Cherokee w/tow and off road package.
Seems the dealer used reg fluid instead of synthetic as what was called for in the owners manual. Tow only required synthetic. The heat broke down the fluid and burned up the gears.
Now a days they all use synthetic, tow or not as far as I know.

If you are with in the 3/36 original warranty, a Max Care Life is a good idea especially if you tow and tow heavy.
I got mine because of the electronics, towing and long time I keep it.

I tow and tow pretty heavy. Nothing tough on it now for the rest of fall and winter. Winterized my trailer and put it into storage while using a Hemi-powered Ram while my TH was being worked on.

Mine has been in the shop for 2 weeks for the SVC 4WD light at 21k miles. When they called, the service guy said they were replacing the PTU, but then in the next sentence said PTO. At the time I didn't realize there was a difference and thought he had just mis-spoke. He did say it was a $3000 part.
