there was a post up the other day that had a link to another site with all the diff options on sierras and mk3 granadas,i cant remember what one it was to try and find it,what i want to know is can i swap the drive shaft cups from an xr4x4 diff onto a 2wd diff so i can use the 2wd diff in the 4x4 beam with the 4wd rear shafts,also what do i need to do to the diff/beam to fit the 2wd diff

 

anybody

 

I dont knwo about mk3 granadas but I do know that you cannot use a 2wd diff with 4x4 shafts.

To use a 2wd diff in a 4x4 beam you need to chop off a mounting lug on the beam and re-weld it 1/2 inch over to accomodate the bigger width of the diff (7 inch versus 7 1/2). You also need to use 2wd shafts, these fit fine into the hubs and arms etc.... so basically to put a 2wd diff into a 4x4 beam you need diff and shafts & a grinder/weld set.

yes ,you can change the 2wd cups for the 4x4 ones,
just remove the back cover,and release the c clips holding them in.

 

cheers mate i thought thats what i had read but couldnt remember where i had seen it lol can the 2wd rear diff be used with the 4x4 front diff ok aswell,i think ive seen that it is possible to use the 2 together as the difference in the ratios is so little that it should be fine

 

yes it will work ok.

 

cheers for the help mate much appreciated

 

Appologies for my incorrect info, never knew you could put the 4x4 output flanges onto the 2wd diff....always learning new tricks
