4wd binding virbration

[antsarooney]

Hi guys , help really needed . I have a Ln65 with a rover 3.9ltr v8 in it . Right the problem is only when it's in 4wd it has a big virbration and feels like it's binding up to as it doesn't want to roll forward freely at all . Unlock the hubs and all's good . Help .

are both diffs running the same ratio? if not they will bind up as you state

All your wheels the same size????

Wheels all the same.
Have thought about diff ratio and that was probably the next step.
Thanks for help.

One other option is that your front diff has exploded and jammed up. worst case scenario though.

Have pulled front diff apart and all seems fine.
