Anyone with this problem should file a complaint at NHTSA themselves. Having your engine die and/or seize driving down the hwy is a safety issue.

I used a lawyer to lemon law an excursion about eight years ago. Ford ended up having to pay all legal costs and took the vehicle back. After the way I have been treated by Chrysler I have thought about contacting this guy. This was before I knew about the OPDA issue. I should shoot him an E-Mail and see what he has to say.

We used the safety angle on Ford (loss of power on freeway) and they took the vehicle back very quickly. Before we mentioned it was a safety issue they kept trying to fix it.

Nice, wouldn't hurt to ask his opinion on the matter.

I had the OPDA "repair" done today. I stopped in and snapped a couple of pictures.







There was some wear on the cam gear they replaced, not as bad as some I've seen on here, but wear just the same. The OPDA spun like top, no resistance on the shaft.

I picked it up this afternoon, it runs great, no issues. I didn't figure there would be. I had to pay for the "repair" in full ($149.00) and Chrysler is going to reimburse me once I send them of copy the bill and my reciept. They said I wouldn't have to pay anymore than 50%, but didn't rule out full reimbursement.

I don't know what more could have been done at this point, being as how the OPDA units are on major backorder, and even if you get one it's the same faulty product.

I'll stick with the TDT Mobil 1 and hope for the best I guess.

Wow, the wear on my gear is worse and my dealership said there wasn't anything wrong with the Jeep at all. Just goes to show you the level of ignorance we are dealing with concerning this issue. Hope it works out for you Jeffro. So did they replace the cam gear? Or the entire OPDA?

Just the cam gear.

Just to be clear it was the cam drive gear, on the OPDA, not the gear in the motor.

Okay, sorry I misunderstood you. That makes more sense, that's chrysler's fix for the problem...just keep blowing through gears

Your wear pattern on your OPDA doesn't look bad at all in my opinion compared to what I have seen.

So what exactly is the failure rate for the OPDA on the 2006's mine currently has no pressure or noise issues with 50K on the clock I might pull it to check for wear.

I believe it was replaced before it ever left the lot. I checked the service records on Jeep.com and there is no indication it was performed after being purchased by the original owner, so I can only conclude all of the miles on my jeep were put on with the replacement gear (53k).

That was a pretty interesting read you pointed us to Chase. I particularly found this interesting concerning new distributor gear "break in".
(from http://www.classicinlines.com/DizzyGear.asp)
"A distributor gear needs to be broke in, following exactly the same procedures as you would for a rebuilt motor (running the motor at 1500-2000 rpm for twenty minutes). During the distributor gear (or camshaft) break in period provide additional lubrication by coating the gears thoroughly with zinc or moly break-in lubricant. This should be applied to both the cam gear and the distributor gear prior to installation.

Some cam manufacturers recommend installing a new or reconditioned distributor gear whenever the camshaft is replaced. The reason for this is simple. The cam and distributor gear actually seat to one another during the break in period, similar to a cam lobe and lifter. Once this happens, the distributor gear may not seat properly to a new camshaft gear. It may also be beneficial to lap the gears prior to break in, as discussed later in this topic. Never use an old worn gear as this may cause premature failure in short order.

DO NOT use synthetic oils during the distributor gear break-in period. Subsequently, any suitable 30, 40, or multi-viscosity oil (i.e. 10W30) can be used. Always verify gear wear after a break-in period of several hours, looking for proper mesh, tooth alignment, and/or excessive wear. Many gear failures are due to improper (or lack of) distributor gear break in."
Also, it talked about proper end-play being a factor in improper gear wear.

SLACKSUPERSTAR- Check your OPDA soon. My 05 LJ has 50K on it and Mobil 1 for at least 1/2 of that. The tip of the gear tooth is razor sharp. Meaning that the gear is wearing into the back side/non-wear side of the tooth. If for no other reason, check it for the piece of mind. It is easy, Just follow the video.
