Adios PTU... at 25k

Like others (@Ampmtnbkr2, @hedblad), my PTU is being replaced.

A note; i didn't have any errors thrown my way, nor was there any change to the the handling or feedback.

It was just a rubbing/grinding sound between 5-30mph. Sounded like a wheel rubbing in the well.

Well, its not. PTU takes about a week to get in. 2+ days to replace... or so I am told. It is also safe to drive... again, or so I am told.

Lost my PTU last week. apparently it was failing. i had not heard any noise. It just failed while I was at a stop sign. I hit the gas to proceed and the Jeep didn't move then there was a loud clank/thud and the jeep took off. It continues to make a loud intermittent clank and deep hum. Took the dealer 6 days start to finish to diagnose, (the rear diff was destroyed - they had to replace it before they could further isolate the cause of trouble) get parts and put it back on the road. Got it back last night. So far, so good.

oh, 28K miles

29989 on mine. Rear guts as well. Very fast replacement, just getting it from warehouse to your shop. Got mine from Portland, OR to Spokane, WA in a day, replaced the next. Light came on mine (4WD SVC) but drove great nonetheless. Noticed "grumbling" in front end but was told it was tied in to the PTU.....guess my thinking it was in the front was actually midships!

Yes... thank god for the max care plan. PTU ain't cheap.

Sadly, the logistics system for East Coast dealerships seems to be lacking. Takes around 4-5 days per part (PTU, exhaust bracket, etc) from Safford Jeep in Springfield, VA. So it goes, just want to get it fixed!

My PTU and MDU went a year ago I was driving on the highway and the service 4X4 light came on other than not going into 4WD it ran just fine. Due to back orders it took over two weeks to fix.

Done - glad I had the warranty... "Good thing you had the warranty... that would have been like $5000."
