I replaced my OPDA with a Dorman unit last weekend. I didn't bother looking for the TDC marks on the front of the engine as I simply rotated the engine until the OPDA holes lined up, assuming that had to be TDC. My Dorman unit did not come with a new gasket so I reused the gasket that was already on there. I got lucky in that the oil pump drive was clocked perfectly on the Dorman unit so it lined right up with the oil pump first time. The gears on the OPDA still looked great with very little wear. Super easy job.

My original OPDA failed with laughing monkeys at about 5,000 miles and was replaced by jeep under warrantly. This was late spring/early summer 2005. The Jeep now has 16,000 miles on it and I started to hear a squeal on cold start up, which the original OPDA started doing before progressing to the full failure mode. There may have been nothing wrong with mine this time, but for $80 it was worth the piece of mind.

My question is, were there any units provided by Jeep that had the bearing lubrication defect fixed? My factory replacement unit has a sticker on it that says:
LDI Inc.
P/N: 53010624AC
105194-REV-E

Just wondering if it would have lasted had I not pulled it out. Pictures below:

Bought mine at Rockauto for $78.89 plus shipping about 2 weeks ago. No coupons or anything, that was just the price on their website.

Weird that it would fluctuate $60 in that short amount of time. Supply and demand I guess.

Screw it. I bought one off of ebay. Cheap peace of mind. Just spent 14k on the LJ but I want it to last as long as possible.

No, all units were built the same way. They fixed nothing. The REV number really means nothing.

I had the laughing monkey on my 2004 TJ at 126,000km. Replaced the unit ($35 rockauto) last night and everything was perfect. Spinning the shaft on the old unit produced massive vibration in my hands and a dry bearing sound. 100% better now.

hope this helps pre 05/06 guys who think this can't effect earlier models.

I don't think an 04 has the same OPDA design as an 05-06

These are not my photos, but my bushing looks exactly the same.

I had Bigbob do the stripperguy mod for me a while ago and recently threw a P044 code. When I pulled the OPDA my bushings looked just like this guys. So what is the best fix? I expect if I put new bushings in I will end up with the same problem. Am I better off to just order a Dorman unit? Are the Dorman holding up better?
