When turning the OPDA, like a distributor, there is only a small degree it can be turned either way before it shuts off so I cant be far off. The engine runs pretty smooth, but jostles when I am driving at about 3 grand.
Look at this video. https://youtu.be/McrtZ6ptSWY
Make sure you have the pulley mark lined up perfect.

On my '06 there is a groove cut into the harmonic balancer and an alignment "pointer". I think you need a 3/4" socket or boxed end wrench to turn the engine and removal of the serp belt makes it easier. If I remember correctly you turn clockwise facing the front of the engine. Once you get there you will be able to see how far off the housing alignment hole is from the tone wheel alignment hole.

Rubi4MyMrs Bucking & surging at higher RPMs or under heavy acceleration can be fuel starvation from a (going) bad fuel pump.

I am pretty sure I won’t be able to get the manufacturer to pay for the repairs, so I need to know what to do next? What else do I have to replace? Is it the actual camshaft? And having never done this what is the difficulty level?

There are a couple more up to date threads on the OPDA here so if you haven't I'd search and read up on those. If you have the original cam sensor try using it. Are you getting codes? Are you 100% sure the OPDA housing is clocked correctly? How does the wiring and connections to the OPDA look? How badly was the original OPDA gear worn? Shine a flashlight down and look at the cam gear? Hopefully your cam is not shot, rule all these out before going further. Mine was bucking and turns out I had bumped it before tightening the hold down bolt. I set it with the TDC method and it's been fine ever since.

I changed mine out from stock at around 50k or so I think. I have some photos somewhere in the big Opda thread. I had normal wear on mine, no noises. Haven't had any issues yet with the Crown unit, and hopefully I never will

Use the factory cable/sensor when you install it. I also coated the opda gear with assembly lube on the new unit before install.

Which part did you order? A stock replacement or a Crown opda?

Had it towed home and a new MOPAR opda installed. (doorman and Crown hadn't yet started selling replacement parts yet and Mopar was the only option). Havent had any issues and have about 76k miles on it. However over the past week sporadically I have started having an issue where its runs and drives great but sometimes when I turn it off and go to restart it I get a odd clicking noise from the dash and the gauges go nuts. Installed a new starter last year and battery is good so pretty sure I can rule those out. Just ordered a Crown opda replacement figuring it was a good idea to replace anyways and going to pull the old one as soon as it arrives. Hope the odd no start issue is as easy a fix as that and will keep updated
