FIRST OFF, I am 1000% happy/satisfied with Bayside Chrysler/Dodge Jeep, and their service/parts/sales department. I have had nothing but good experiences with them
I bought my 2005 Rubicon brand new in August of 2005. Since then, it has been dealer serviced every 3000 miles, no steps skipped. I have not abused this vehicle in any way, and it is 100% stock, except for factory sized Goodyear Duratracs, Mopar floor mats, and a Mopar trailer hitch. I have used/driven this vehicle, but I have not abused or neglected it in any way.
I am sure that some of you have heard the stories about the OPDA failing in 05-06 TJ's. If not, here is the story:

Basically, there was a bad batch of these things made. They recalled "some" of these units, but not all of them. My VIN code fell within the range, but Chrysler Jeep WOULD NOT REPLACE IT UNTIL IT FAILED.
It is my personal belief that a certain number of these OPDA were made totally incorrectly, resulting in low mileage failure. My '05 has 143,000 miles, so I believe it was at least "made to spec", even thought that spec is crap.
Another interesting note, ALL 1999 and up TJ's OPDA are made the same with regards to the stupid upper bushing design:

Back to me. While driving 70mph on the interstate the other day, my engine violently bucked/stalled out. Not good with a semi 2" from the back bumper. I managed to get it to the side of the interstate. The engine was still running, but would not rev over 2,300 RPM. The check engine light also came on. I limped down the shoulder to the next exit. We found an Auto Zone, plugged in a scan tool, and I had an "intermittent cam sensor failure"??? And of course, no one has the sensor in stock. After disconnecting the battery for a few minutes, the code disappeared until the engine got over 2,300 RPM. As soon as it did, it would buck, like hitting the rev limiter. I got the Jeep home and parked it.
The next day, I obtained a new sensor. Before changing the sensor, I decided to take a look under the cap of the OPDA. And sure enough, the upper bushing no longer exists, causing the sensor ring to flop around. The shaft moves so much side to side that it will hit the sensor. No sense just changing the sensor.
I ordered a new OPDA from the dealer today. After ordering the new OPDA, I called Chrysler's "Customer Care" hot line about my problem. I gave them my VIN/purchase information. They informed me I would have to bring the Jeep to the dealer to be diagnosed. OK, I can understand that.
BUT, if I take my Jeep to the dealer, I will have to pay $90+ to diagnose something that is clearly broken. And I still have to buy the part, and then Chrysler/Jeep MIGHT reimburse me for their F--- up??? Which should have been covered under their TSB along time ago. But, conveniently for them, it is out of warranty.
I know some of you will say "But it has 143,000 miles on it, why are you complaining?" Well, this is a very well know issue, and even the new OPDA are made with the stupid sealed upper bushing that will fail. Some very ingenius individuals have found ways to "cure" this, but I really believe Chrysler/Jeep should step up.
My biggest concern now is that the lower bushing "MIGHT" be shot, too. If so, I probably munched the camshaft gear that spins the OPDA. Yeah.
I am going to pull the OPDA out tomorrow, once I get the "replacement" unit in my hands. If, upon pulling the broken OPDA I discover the cam gear is toast, looks like "rebuild a 4.0" time. Yeah. Hopefully, the lower end will be OK. If not, I will have the engine repaired, at my cost, due to a Chrysler/Jeep design F--- up, that they know about, that they issued a TSB about, but then they act like its not their problem.
Once I get this vehicle properly repaired, it will be up for sale. I know other vehicle manufacturers have similar issues, so be it. I have not experienced this from anyone but Chrysler/Jeep, so unless Chrysler makes this right, which I doubt, I will never buy another new Chrysler/Jeep vehicle again. Not much of a "threat" to Chrysler, but that's how I feel about it.
So, if you have a 1999+ up 4.0, might be worth your while to at least pull the black plastic cap off the top of the OPDA (two T25 torx screws hold it down) and inspect it for excess lash. It might just save you some money/headaches.
I also found this, from NAPA:

It is "pricey" compared to the defective Mopar unit, which costs around $150-$180, but maybe it is a better design?
I will post a few pictures.
Mileage, check engine light on, I can't remember the "code number" that displayed, but it was "intermittent cam position sensor failure":
And a picture of the top of the OPDA unit, showing the black cover that can easily be removed to inspect it for excess lash. The two screws look brown, the camshaft position sensor is sticking out the side to the right, the oil filter is on the left.
I will update this thread as needed.
