Re: What Diff For XF

i'm sure i've told you this before. no need to redrill holes just swap them over but change the yokes, lower control arm bushes, handbrake setup and wheel nuts!

Re: What Diff For XF

the handbrake setup is completely different and i haven't worked out how to do it yet on mine (i still have no handbrake), the lower control arm bushes on the EF/L are wider than the XF ones at the diff end - just buy the two bushes needed and then get the xf ones pressed out and the EF/L ones pressed in to the xf arms. the yoke is the part that sticks out from the diff that the tailshaft bolts into. the EF/L one is different again so i used the XF one on the EF/L diff.
