This is a quote of LDI's web site - good for a bit of a laugh.

" Thanks to decades of experience, extensive market knowledge and not least, to our intensive customer care, we consider ourselves a global leader in these fields."

Classic, they took a distributor design that's worked for decades and screwed it up.

Just to clarify. I now have the laughing monkey. I am under extended warranty through mitsu/kia. I expect some issue getting a new opda ordered in. Will I be fine to continue driving on this until they can repair it and just take my chances on my internals grenading? Do we have any idea on a lifespan once the monkey starts laughing?

I have the TSB as well but hesitate to go to my local jeep dealer as I really can't afford to fix this out of pocket. I also cannot afford to be without my vehicle fo weeks/months...

I understand milage doesn't necessarily determine when the OPDA fails, however, I'm interested. What was your milage when the "laughing Monkeys" began?

I just took apart my old OPDA. It had 49,000 miles on it. I had no symptoms, but the gears were somewhat worn (post #1579 here: http://www.jeepforum.com/forum/f9/ch...l#post10843742).

The upper shaft was coated in horrible black burned gunk, the bottom is grooved, and there's a very deep groove in the shaft where the seal below the upper bushing is located. I cleaned the shaft and bushings with WD-40 and put the shaft back in the housing and it turned so much easier than before.

I'd recommend at least disassembling the OPDA, cleaning shaft and bushings, and then reassembling it with a bunch of grease or oil in there. That ought to hold you for a while, as long as the gear isn't in too bad a shape.

But, get it diagnosed first. They might be able to get an OPDA quickly now.

kgginslc,
Any photos? The grooves in the shaft are interesting, especially at or near the seal area. Is it around the shaft or vertical? Is the bottom grooving like from the lower bushing wear? Tkki has been having more trouble with the bottom bushing than the top. Makes one wonder what is going on here.

Ahhhh, the "laughing monkey." Like death wobble, you will know what it is right away! (No one ever said, "Is this death wobble?" or "I wonder if that's what a laughing monkey sounds like?")

Can anyone provide some definitive input on this subject? This has been brought up several times and it eats up a lot of thread. Instead of repeating things here can someone PM me a "write up" so I can update the first page?

I have never done only a gear mod. I believe the holes for the crown gear will require an new hole be drilled in the shaft. The actual gear teeth will work with the camshaft though. Another option that was discussed was using the gear for the 2004 OPDA. The hole in the shaft can be reused provided it was drilled close enough to make the new gear work (drilling of the new gear is required).

For those of you who changed the gear only:

What gear did you use? Part number, website link, cost, availability
What modifications were required? Drilling the shaft, drilling the gear, shimming
What are the results? Gear wear pattern, how many miles, problems during the process, tools required

Let's nail this down so we can post it up. Thanks!

I drove with the laughing monkey for a few weeks. When I pulled it there was substantial binding and I wouldn't recommended driving on it. I would contact the dealer. The new OPDA's are in so you should be okay with getting one.

If you can't get one immediately, pull the OPDA, knock out the roll pin with a 3/16 punch (home depot). Remove the shaft and clean it with some degreaser or WD or PB whatever. Scour it with some 2000 grit or a scotchbrite pad. Find a way to clean the bushings. A dremmel with a polish wheel or a rag with a screwdriver. Lube it up with whatever grease you can find and make sure it will spin freely when you reinstall it. You may also need a new gear. Take photos so you have a record.

Kia will be looking at my heep on Monday. My local dodge dealership has no clue what I'm talking about and their database shows national backorder for parts. They could not find info about affected 06 model years either.
Good luck to anyone trying to get this fixed...no one seems to have any clue when u start asking questions.
