B5m bearing/ diff tight Qs

[OneKiwi]

Hi

Was it only the front crush tube that was binding or something in the rear as well?

I have the M with gear diff and when I remove the pinion it doesn't spin/free roll as much as a club mates with ball diff.
I ahve refilled the diff and I noticed that the outdrives were pretty tight in the diff casing. Should they be tight?
I did remove all diff case inner bearings and blew them out and reoiled, that made a fair bit of difference, now the slipper shaft can spin freely unlike before.
But it still seems like something is too tight

My next option is going through the hub bearings and after that replacing all the bearings and trying again

Any tips or thoughts?
