So I can say with absolute certainty that part #68338342AB works on 4th gen 2500s. Install was super simple.I did spray the tapered fits a few hours before with PB blaster, not sure if it made much difference. Definitely get a Pittman arm puller for the Pittman arm side. The knuckle side I smacked good on the knuckle and drag link a few times then used a brass hammer and gave a smack on the bolt on the ball joint and it popped right out. I made a match mark on my Pittman arm for reference so I could get close when adjusting it. I followed the recall bulletin torque values. Torqued the Pittman arm nut to 27ftlbs plus an additional 180° rotation on the nut. This turned out to be about 135ft lbs. Knuckle side was torqued to 44ftlbs plus 105°. This was about 70ftlbs. Coming off this nut was extremely loose I doubt it was more than 25ft lbs.
Broke the locking collar loose and spun adjustment sleeve easily by hand to move the steering wheel to where I needed it. Took it on a drive and had to make further adjusting. After I got it set I match marked the position of everything and torqued the lock collar to 55ftlbs.
ETA: I also made sure my old and new links were close in length before I installed to minimize my needed adjustment
With the adjustments and drives down the road to check the wheel maybe an hour and twenty minutes total. Easy job but definitely invest in the puller!
