There are two different ways, I usually accomplish removing this style pinion flange.. The first is at my build bench or outside on the drive still within reach of the airhose. That method is with my dealership pinion flange holding tool. Kent Moore made the 2 piece pinion flange tool and it has several recessed slots in the head. in these recesses a a cast hub type piece pops in. one inserts the hub, backs up the threaded puller type bolt in the center, then bolts the flange tool to the pinion flange. On an 8.2, I use a pair of longer grade 8 bolts, a few thick washers, and towards the housing,lock washers, and the two nuts. Once the pinion tool is tightened up to the flange, use either the small impact, or my ratcheting 1/2" break over with a 2 1/2 foot piece of pipe and the pointed head on the puller bolt pushes against the pinion and pulls the pinion flange off.
Out in yards, when pulling ring and pinions I typically wont haul the Kent Moore tool flange in. Over twenty years ago, an old friend and I were pulling rearend parts west of Ft Worth, and his Kent Moore pinion flange tool never made it out of the yard with us. we suspected the lone guy in the yard on the loader, having picked it up, but couldn't prove it. Real frustrating end of the day, and it took a week to have a nice flange holding tool made, that while the same shape up on the head of the tool, it no longer had the insertable hub with the puller feature. Out of that occurrence, I had a local company lazer cut a few pinion flange holding tools out of plate steel, just in case, we bent one, or lost one.
As a result of the no puller feature, on rears in cars in the Pick N Pulls I'll get the pinion nut off, then take a HD ball joint "pickle fork" and alternate whacking the back side of the flange with the HD pickle fork with alternating positioning and lstrong swings of the mini sledge. The two flat forked tips of the pickle fork tline up on the back of the flange and other than a few light impressions in the cast steel on the back side, no damage, the flange will come off and if needed, the flange will be able to be reused. I've never had a flange in the Pick-N-pulls I couldnt get off this way, it just takes a some muscle. The ball joint separator/ pickle fork needs to be a HD steel one like the large gray ones from Sears. The shiny cheap tierod end/ball joint separators from Harbor Freight, et all, are made off too soft a steel, and the pointed ends will roll over on the ends. misplaced the heavy steel one from Sears years ago, didnt make it into my truck. Picked up a cheap HF one while on the road, and it barely got the job done when I was pulling some Pontiac 8.2 3.23 gears later that day.
