FOG - That is interesting information. I didn't realize the unit had been replaced already. What is your recommendation for me @ this point? I've changed to a decent oil, am thinking about installing a new (Rev-E) OPDA and installing one of Hesco's high volume oil pumps w/ the sprayer tube that lubricates this gear. Any other advice?

Does anyone know if the Jeep engineers are actually aware of this problem & are they going to get us another part made OR are we SOL as they know these models/engines will soon be dropping out of warranty so it won't be their problem any longer?

I have a 2006 and I'm the original and only owner. My OPDG assembly has the REV E. I doubt that it was repalced back in September of 2006 when I bought it.

How long ago did you install this? Did your gear fail before you did this?

Have you checked your wear since you installed it?

I'd be interested to know ho much of a permanent solution this is or if it's another band-aide.

I pulled my OPDA this afternoon. My vehicle build date is 5/06 and the engine build date is 1/06. I am very fortunate in that my gear showed very little wear.....it is really just a bright spot around 1/3 inch long on each tooth. No wear on cam gear. I now have a check engine light on, so I guess the timing is off a little. Before pulling the assembly, I marked the tone ring in 2 places and also pegged the tone ring against the housing with an allen wrench. I also marked the housing as relative to the mounting strap and block. I guess I am off to the stealership tomorrow to have the cam timing reset.

I am one of those that just got lucky (so far)....but I still don't trust the jeep for long trips. By the way, I always use Pennzoil Platium 10-30 and Wix filters.

After seeing your posts, I checked the maintenance records I got w/ my '06 LJ, checked the Jeep website, and then called the service dept. My '06 DID come with a REV-E part, from the factory. It has never been changed, positive.

Well then I'm wrong about the REV-E units. Its just I've seen a bunch of 06 TJs with REV-D units including mine. Supposedly the REV-E units where made after the end of the TJ production line when the E-05 TSB came out.

My dad just had his OPDA replaced on his 2006 Jeep Original date code for the defective unit was: 106017 REV E...the NEW OPGA date code is: 106132 REV E

So can someone explain how to read the date code?
Thanks

Likewise, I have rev E. Checked the assembly today. Date was 2/06 on the OPGA. I had "even" wear all the way around the gear. Some wear at 20.5k miles. Doesn't look like anything to be too concerned about at this time. I will keep an eye on it. I am running mobil 1 HM 10W-30.

Great discussion!

I hope Chrysler engineers are allowed to talk as openly as in this thread. But I doubt their management cares, since warranties are expiring.

My 2001 TJ's upper end was rebuilt this year (cam, lifters, etc.) b/o damage related to oil sludge/inadequate lubrication. Although it runs great now, no way I would take it on a long trip, if you know what I mean.

Recently, I almost bought a 2005 Rubicon LJ. Now, I'm wondering if a JK might be a better idea for the next 5-10 years; low interest rates are very tempting...

Hmmm..., mine is 105132 REV-B

I just bought a 2006 Rubi two months ago. I have read this whole thread, and have worried it to death. If I had it to do over, I would still buy a low mileage 2005 or 2006. The last of the great ones.

No the gear did not fail in fact it's in excellent shape but I only have 10,300 miles.

IMHO, I believe it's the lack of lubrication and oil with insufficient amounts of zddp that's causing our problems but obviously the jury is still out.

Installed Hesco pump as a precautionary measure. FWIW, I've always used oil in the jeep with higher than average zddp ratings because of experience with "older" engines in muscle cars.

Along with the Hesco pump, I'm also adding a zddp additive. I'm not worried about catalytic failure...besides my engine isn't buring oil in significant amounts to cause catalytic failure from "too much" zddp. Purchased the zddp additive here: ZDDPlus™ - ZDDP Additive for Classic Cars - Agricultural Equipment & More

Installation of Hesco pump was on Monday of this week so no opportunity as yet to check for wear.

I don't know if this a permanent solution or a bandaid but I'm betting it'll help.

Peterpsc - Can you tell us anything about the Hesco pump, and the installation of it? How is the quality compared to OEM? On your '06 LJ - did you have to modify the pan to install it? Wondering specifically about pan baffles as I haven't pulled one myself.
