How To Remove Front Diff Pinion Fuuuuuuuuuu

[RBish]

i am doing a 32 gts4 rb25neo conversion and have to swap the front diff centres, i have everything gutted form both sumps except the front diff pinions. thes are really tight, i have been trying to jam it up and rattle them off but no luck..

how do you get these pinions free?

3/4" rattle gun.

Hold the pinion tight somehow, undo the nut. The nut may be peened so that will have to be knocked out. Usually a 1/2" rattle gun can undo the nut

i had vice grips on it and tried a screw driver to jam it up. probably my weak ass bluepoint rattle gun. will take it into work or into a jdm workshop to undo it and rebuild the diff back up

[RBish]

its not peened either

removed the pinion nut today with my 1/2" rattle gun at work, the workshop air compressor really helps... and knocked the pinion loose with a copper hammer. now i can get on with this build, thanks.

When I did it, I had to use a 3/4" drive socket and a breaker bar about 3 feet long! Shove a screwdriver or big bolt through one of the flange bolt holes to lock against the diff case.

gts4 diff centre and pinion are now in the rb25 diff. backlash is the same as before it was disassembled. i am a happy man
