got an 8.8 i pulled the coer off, drained the oil. pulled the c clips, pulled the axles, pulled the ring gear, kept the bearings and races and seperate. cant get the pinion out... got the nut off and the flange the driveshaft bolts to. i have beat it with 3 lb hammer and a block of oak and it will not come out.

So just to make sure, you are hitting the pinion gear towards the back of the axle right (towards where the cover diff cover would be) ?

The wood is excellent in protecting the threads from damage but sometimes you need a bit more “shock” to get the pinion out.

I would screw the pinion nut back on until there’s about one thread from being flat with the pinion threaded end, then place a pc of scrap metal on the end making sure the nut is the only thing in contact. Then give it a solid knock (don’t have anyone standing on the other side although if it does shoot out it will catch the pinion nut). If it doesn’t come out then remove the scrap metal and inspect for damage. Repeat until it comes out but I can’t caution enough to make sure and not hit the pinion end or you’ll never get a pinion nut back on.

Also, replace the pinion nut afterwards (don’t try and reuse the one you hit) You’ll never get the right torque values from it.

They arent supposed to be that difficult to remove - something is definitely wrong.
