Do I need to worry about the ODPA issue?

I have an 06 Rubi and that was manufactured in October of 2005. According to the report I read only TJs built between Oct 04-Feb 05 need to worry. I have 42,250 and no signs of any problems yet (at least ODPA issues!). Should I worry?

All 2005-06 wranglers are able to develop the dreaded OPDA issue. Best thing to do is take the camshaft gear out and check for wear. I have ~70k miles on my 05 with no issues yet. Have yet to check the gear.

I figure it won't hurt to pull it out and take a look. What exactly should I look for?

Any time that you have a serious defective issue, without a solution from the manufacture, then I would really be concerned!
It is really sad when we pay our hard earned dollars for a product that we all enjoy and the factory turns their heads and ignores the problem!
I wish that this forum would put more pressure on them to work on a solution. I don't have the issue, because mine is a 2003, but my friends is a 2005.

I personally don't "worry" about the issue, but I am definitely aware of it. I think it's wise to add it to a regular maintenance check. Just pull the camshaft gear every X thousands of miles to check for wear. If there is any, it's time to swap it out. I think of it as just another part of the routine.

Yesterday, I read that there is a replacement available from Dorman that can be purchased from www.rockauto.com. Part number 689201. I'm now researching to see if it's an improvement over stock. Looks like it's the same size and everything (direct swap) but they changed a couple of key features so the oil reaches the top properly, which should negate any wear issues. From what I can understand, anyway. Worth researching so you know where to get a replacement if you need it.

Our '06 is at 67k. No issues yet (since we've had it, anyway).

Any time that I own a expensive item, vehicle, television, home or whatever, that has a known product issue and the manufacture that made a profit off of my purchase, or one of my friends purchases, refuses to acknowledge the issue, then I am not only concerned, but I am very angry over it!. There should be a law forcing them to find a solution and perform a repair campaign!
Not everybody worries about the same things in life. I just happen to be a pro-active person, that doesn't make me good, or bad, but that is just who I am.
I AM VERY HAPPY FOR YOU THAT YOU HAVEN'T HAD TO THINK TWICE ABOUT IT!

I have an 05 Rubi.

When the OPDA starts to fail, it will make a very odd noise. and you will need to replace it. As I understand it, when it does fail fully, the oil pump will stop working and there goes your engine.

A week ago I started getting the noise occassionally. I am replaceing it this weekend. I bought one from Rock auto for $180. Suppose to be the best and won't have to worry about it again. I have 148 K on the clock right now.

I am sure there will be other things that is going to be repaired or replaced as time goes by. Part of owning a Rubicon.

The "screaming monkeys" will start and quit then come back with a vengeance. I have 95000 on mine and they started doing a little chirp just once in a while so mine is getting changed this weekend also, if you have the engine running go to the gear assy on the right side by the oil filter and feel for a pretty solid "knocking" if so you are probably going to need to replace it pretty soon,. Jeep had a revised part B and then an E but they were the same design as the first and they also fail so go with the Dorman, new design internally and different material on the gear. Look at JF as they have a ton of information and there are videos on Youtube on how to replace.

From what I could find, the actual service bulletin (and not a recall) is for '05s, not 06s (though there could be some cross over I guess), and it might affect about 16K vehicles. Clearly a design flaw, but I think the scare is largely overblown and at 116K miles in a late '06, I'm not worried at all. Same sort of scare went through the Porsche Boxter community with an "intermediate shart bearing" failure... It was a real issue, but rare and did not influence me in my decisions and I never had a problem. Ditto with a Kawasaki KLR650 and the "Doohickey" (cam-chain tensioner). Naturally, when even one person does experience this problem, and posts it here, everyone gets alarmed. Also, in the case of the OPDA and the Doohickey on the KLR, the prevention is relatively cheap (not so the Boxster), so buy the Wrangler with the 4.0 and make the fix right off the top or wait for the noise (that may never come).

Because this is an older thread I might as well update it. I am at about 44,550 now with no signs of a failing ODPA (knock on wood).

Be careful as there have been cases of OPDA failures that didn't show symptoms, ex. laughing monkeys. My understanding is the reason it's only the 05/06s is because there was a change in the ecm from 04 to 05 which required a completely different OPDA. The newly designed OPDA on 05/06s looks entirely different than 04s, 04s being much smaller. If you ignore it, that's fine, just be aware of the problem and if your OPDA fails without showing symptoms don't be surprised. The best thing to do is replace it with the dorman unit whenever you can, whether you have symptoms or not, unless you like to gamble with your engine. The risk is too high IMO for something that can be address for a couple hundred bucks and the added peace of mind is well worth it. It's a shame Chrysler didn't address the issue...

Pick up a automotive stethoscope and listen to the opda will pick up any issue before you hear it with your ear early detection...don't sweat over it.

Tomorrow We are looking at a Rubicon with 148k miles.
This OPDA issue worries me.. Do you think it will have shown itself by now if it was faulty on this Jeep?
I will ask for records etc.. And listen/ feel for a noise as mentioned above

I would think you are safe with it having so many miles. It would not hurt to inspect it and if you do buy it I would take it out and look at it. It might be worth replacing for peace of mind.

It is worth it as long as you are aware and check it.

I have an 05 rubi iwth 148K on it. I change the ODPA. easy task to do.

$180 is not much for an Dorman ODPA. garenteed for 5 years

I like my 05 but I am not crazy about the 6 sp tranny. just to many gears.

I got mine for $12.5 grand with a set of brand new tires on it. It did need a little bit of tlc to take care of a few cosmectic issues but nothing that would stop you from wheeling it. going to get it dirty and scratch anyway. It has a hard top and a/c.

I will tell you this gas milage sucks. 15 mpg is good.

I love the 6spd manual -- skip some gears if you don't need them.

I have an 06 with 47,000 miles on it. No problems with OPDA that I am aware of. I do have a couple of questions concerning this.
Is there an improved replacement available now? (It has been a year since the last post)
Why did jeep decide to make this 05-06 OPDA? Did they just have an open place on the block since they did not use a distributor for these years? Or was this considered improved technology?

I plan on buying an '05 shortly and swapping out the OPDA will be one of the first things I do. Piece of mind, mainly.

The Dorman is still the one and only replacement OPDA worth buying IMO. I have an 05 with 79xxx miles with no issues, but I will be replacing mine with the Dorman for the peace of mind.

I used the Google Machine to look for the Dorman part. I could not find anything that looked like a direct replacement. Is it the parts kit SEALED POWER 22451198?

I've been researching this issue and thought I'd bring this thread back from the dead to post a small update.

Crown has started producing an updated version of the OPDA, it looks to be a superior design.

It can be bought through a few resellers, here's a link to quadratec.

Just dealt with this issue over the winter. Jeep sounding like "laughing monkeys". Ordered the dorman unit, replaced it, no issues. Permanent fix....who knows...piece of mind goes a long way. Gears were fine on the cam but looked like shit on the OPDA.
