    and what to do:
    i just got back in here and washed up from removing 14 bolt FF yoke, it took ALOT longer to remove due to the following reasons:

    1. axle shafts removed and axle not on vehicle
    2. did not remove the washer under the pinion nut before 3. beating directlyon endofpinion gear shaft with a hammer in which mushroomedthe endof said shaft and therefore washer will not slipoff endofpinion gear shaft !

    soi had to go get the straight air drill and tapered steel cutting dremel bit and go all around the endof the pinion gear shaft to remove mushroom, took about 5 times before i finally got enough removed to getthe washer and therefore the yoke off the shaft splines and therefore removed,in which was all i wanted to do !

    ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh !!!!!!!!!!!!!!!!!!!

    so for thoseof you who go to remove a yokeoff a pinion gear: do not use hammer directlyon endof the shaft, do use a long skinny pointed steel punch and do remove the washer along with the nut before starting to punch the gear through the yoke !

    i basically ruined a 3.73 14bolt FF pinion gear... unless i can getthe nut tomayb thread onto the shaft...... maybe....

    anyone know ?

    about a good 3/8"ofthe very endof the threads are gone and tapered down now after all this,.

    i have taken many 10and 12 bolts apart and also dana 44 also i believe, and those yokes come off pretty easy, unlike these 14 FF ones.

    phew........

    I mucked the threads of a 14FF pinion after dropping it /forums/images/graemlins/blush.gif. I was able to find a machine shop that lent me a spare dye to re-cut the threads. If memory serves me (don't bet the farm on this) it was like 7/8" by 18TPI. I also checked how much one would cost to buy.......lets just say, hopefully you can find somebody who will let you use their's.

    You should never beat on the pinion shaft. It can change the crush sleeve setting and ruin the bearings. I made a simple puller and it comes off with ease. /forums/images/graemlins/thumb.gif

    Good point!

    My father made one up for me out of some thick flat stock. Two bolts bolt diagonal (where the u-joint strap goes), and the center was drilled and tapped. As the center bolt is screwed in (grade 8 fine thread), it pulls the yoke off, just make sure the stock you use is stout as there can be alot of force exerted on it.

    too late now, is parts only axle, now, wasperfectly good, isnt worth spending on, IMO
    some strong threaded rod and a nut welded to flat thick steelplate with holesfor threadingtothe yoke would work well as a puller im sure, and beaton the end of the puller instead, but what about the end that needs to sit in/on the endof the pinion gear shaft ?

    grind down to point, or ?

    hmmm..

    picsof tool, homemadeor store bought that works for this pulling ?

    thanks

    danan 44is alot smaller, this one is 1 1/2" nut and has a separate carrier justfor the pinion gear and the bearinns rid in it, dana 44 and 10 bolt and 12bolt areonepiece case, 14 botl FF are two piece case and so are the 47-72 years eaton FF axles too,but not the same two piece design,

    1/2 ton stuff is simple and basic
