clull05rubi Just found that yesterday. Sounds promising. Dorman has been making one for a while now with the relocated seal but not sure it has the oil channel like the crown. Im going with the crown

Read the thread. There's a new OPDA design out. This one.

KC10Chief My new Crown OPDA was waiting for me when I got home today. Up until tonight, I'd never even looked at the one on my 06 TJ with 95,000 miles on it. When I took it out, the gears looked great. It spun nice and freely too. Still, I feel better knowing I have one that is being lubed properly.

Installation was a snap. I disconnected the wire harness on my old one and took the cap off first. I then took a 3/4" socket and put it on the harmonic balancer bolt and turned it until the small hole in the OPDA lined up with the hole in the OPDA housing. This is the point where the #1 piston is at top dead center. I pulled it out and put the new one right in. It really doesn't matter the orientation of the entire OPDA assembly as long as those holes are lined up when you put the new one in. Once it was bolted down, I pulled the plastic pin out of the new OPDA. I reconnected the harness, put the cap on and she fired right up. I drove around town and it's running great. I also used my Mopar sensor from my old OPDA as I'd read people had issues with the Crown OPDA sensor. I figure I'll just hang onto my old one in case somebody in my Jeep club needs one in a pinch or something.

Read through this thread. Also, there is a good video on how to check your OPDA on YouTube. Search for Wrangler OPDA. If yours is bad, order this one made by Crown. Yours looks original. I have an 06 TJ as well and have 95,000 miles on mine. I haven't had any issues. If you are having issues or wear on your gears, get this one by Crown.

SilverTJMike Oil Pump Drive Assembly, and yes it should be worried about, a replacement from crown is only a hundred bucks and the forum has lots of discussion on it. Short story is oil seal is below the bearing causing lubrication to fail and OPDA seizing up, etc. New Crown fixes that issue. Its an 05-06 issue.

Good to go, no lights. Took all of 15 minutes tops. Both old ones had burn marks on the shafts. Crown has new seal and I think grooved shaft for better lubrication.
Thanks!...Crown it is!

NCWranglerX How do you check to see if it's bad? My jeep is doing this http://m.youtube.com/watch?v=yR33TJM06Mk currently and I was pointed in this direction.
08-15-2014 03:11 PM
FTI76 Yeah it is looking like I will. No sense being penny wise and pound foolish.

I see the crown replacement OPDA is about $100, I wouldn't feel comfortable doing this job myself so I would also have to pay for labor. Does anybody have any input? Thanks!
My '06 LJ was perfectly fine until I cranked it up one evening and heard laughing monkeys under my hood. It's easy to check and I would do it if I were you for peace of mind.

Bonita I have a 2006 4.0 Unlimited with 126,000 miles. My husband hates it when I read this forum and find things like this. Then I ask him to check it or show me how to check it. I am the second owner - don't know if it was checked or replaced before. Guess he is going to give me 'the look' tomorrow.
He has a '98 CJ (Hiding behind mine!)

RUBI 4 MY MRS To clarify, that is a reference to a TSB for SOME early '05 TJs. It was for ones with specific build dates AND 8 in the 8th position. Meaning only 4.0s within those build dates. That has nothing to do with the present OPDA issues. It was to replace some faulty gears. My LJ falls within those dates & had the gear replaced. In just over 20k miles there was some shaft binding & the replacement gear had excessive & uneven wear.
05-30-2012 02:57 PM
Dusty Rhodes I just want to mention concerning the OPDA that there is a link in this string which says the 8th alpha-numeric position of the VIN number, if it is an "S" indicates a potentially faulty OPDA. This is incorrect according to the Jeep/Chrysler Service Shop Manual for the 2006 model year.

According to the manual it states that an "S" in the 8th position merely indicates that the jeep came from the factory, with a 4.0 I6 engine. The only other number/letter possibility for the 8th position in the VIN is a "B" which designates a 2.4 I4 engine. Only an S and a B were used in the 8th position.

In all probability, something this simple would likely translate to all of the TJ years.

I am not trying to minimize the OPDA problem, but merely trying to clarify what I read in the manual.

Rayko 05 with 90K on it. No problems, my mech pulled it yesterday morning and said it was OK.
05-30-2012 09:13 AM
-sean- Just a thought:
Consider the OPDA to be much like a timing belt. It could last the life of the vehicle without failing and most will. But if it does fail, it could be very expensive to fix depending on the other damage it causes when it does.
It is relatively cheap and is about as difficult as changing spark plugs to replace.

crisjacof I got 66k on mine and no problems, I'll check it soon. Just to be on the safe side.

Ha I would say you're most likely in the clear with 200,000 miles. Unless you meant 20,000.

Best to pull it and check it out...odds are if it hasnt been replaced you will need a new unit that is modded. Wouldnt stop me from getting it by any means but just make sure you look at it.

SeVeReDiStOrTiOn right on..thanks
05-28-2012 11:25 PM
RUBI 4 MY MRS Punch the pin out & slide the gear off & the shaft comes right out. At least lube the shaft & top bushing with some oil if putting it back in for now. WHATEVER YOU DO, MARK THE GEAR POSITION. IT MAY LOOK LIKE IT GOES BACK ON EITHER WAY BUT THE HOLE IS SLIGHTLY OFF CENTER & IF YOU TAP THE PIN BACK IN IN THE WRONG POSITION IT WILL BREAK THE GEAR EASIER THAN YOU MIGHT THINK!!!!!!!!!! If you already have it off without marking just know it has to line up exactly & if you try it both ways it will be obvious which way it goes.
05-28-2012 10:14 PM
SeVeReDiStOrTiOn Does that roll pin just punch out? I didn't remove the target wheel because I wasn't sure it the pin was reuseable.
