What happened to Big Bob? Just curious.
How did the gears look on the original at that mileage?

Has there been any pattern to premature wear being narrowed down to specific period, other than all '05 and '06?
My '06 OPDA started the laughing monkey two years ago, around 70k miles. Had stealership replace the OPDA and CAM under warranty. She's been quiet since, 85k miles now, but I'm on borrowed time until I install upgraded OPDA.

Any opinions?
Why do you want to put grease in it? The grease will lube the bushing but also act as a seal preventing engine oil to get to the bronze bushing. I'd rather have the engine oil any day.

The Dorman unit has been out a while now...and I can't recall hearing about any new problems with the unit. Most guys seem to replace the OEM unit once and not have any further issues.

If I was you I would order the Dorman unit ASAP. My OEM unit wasn't making any noise but I pulled it to check and there was a good amount of wear on the shaft and gear

I need to pull my Dorman and check it. I have about 1000 miles on it now. The dorman does get lube to the top bushing in the form of oil vapor. A bronze bushing does not take too much oil to stay alive. You figure the OPDA shaft spins between 1000 and 2000 and spins about 1500 at cruising speed. And has about zero load to boot. As far as the bottom bushing wallowing out, that is totally a alignment issue. The bottom bushing takes the brunt of the force from the oil pump load. The stock units once worn are shot for alignment and getting the SG modded units in proper alignment is impossible as I have found out. You also get more side load on the shaft gear if the gears are worn. The only true method to fix this for good would be to change the cam shaft along with the OPDA and even then you may have a bad engine block casting that does not allow proper gear clearance. I think constant monitoring of this OPDA is in order. I'd have no issue pulling the thing every 5-10K miles and checking it. It's just what needs to happen if you own a newer 4.0 Jeep.

Here's a few not so favorable Dorman reviews. http://www.wranglerforum.com/f282/do...-212910-3.html

One mechanic said a lot of this premature wear is due to it not being torqued down correctly. Forgive me if this has all been discussed. I haven't followed this religiously.

I haven't had an issue with mine either. Knock on wood. I pulled it a year ago and everything looked fine.

This problem affects ALL 05/06 models. The major failure is the upper bearing due to lack of lubrication.

A COMPLETELY SEPARATE issue is the cam wear. This can be caused by a bad block or OPDA casting and/or oil issues.

My OPDA went out after 100K and I had no cam wear issues. I ran Mobil 1 Extended Performance which addresses the lack of ZDDP issue which is causing failures to the cam lobes and possibly the cam gear.

Expect your upper bearing in the OPDA to fail at some point. Its going to happen! The cam wear may or may not. Just understand that these are two separate issues...on the same shaft.

I have 10k on my Dorman. The gasket that came with it always leaked, and i just pulled it to replace the gasket with a proper one.

The gear looked just perfect and it spins freely with no play.

So I got the p0016 code the other day and I decided to pull my OPDA to look at it. What do you all think? I have the REV E and I have about 85k miles. After I got the code a couple days ago I ordered the Dorman part just in case from rock auto.

Time to swap it out. That is not a good wear pattern.

That's what I figured. Just wanted to double with you guys. Good thing I ordered that part.

I just hope I caught it in time to save my cam
