4WD pulls

[Runge17]

Howdy! I seem to be having a problem when my 4WD is engaged. I have a 91 4runner and when i put it in 4HI and start accelerating i can feel a vibration in the front right side and the truck pulls hard to the left. I can get it going to about 45 KM/h until it becomes too bad and i dont want to get going any faster, not that I would normally be in 4WD above these speeds anyway but its just a test.

Any ideas what may be causing this? It feels as if there's no power going to the front right wheel. I replaced both C/V joints recently to the book so those shouldnt be the issue. My front-most U joing is needing to be replaced sometime but i dont believe it is that far gone yet.

Any help/suggestions are appreciated, thanks. (Trying to get it in shape for the upcoming Saskatchewan winter).

Nobody?

Hub gears? (not to be confused with wheel bearing). Do you have manual hubs?

They are automatic locking

If you think one of your fronts isn't getting power, I'd stick the thing on 4 jackstands and find out. If you really do have one wheel not spinning, looking at your CV shaft will tell you whether the trouble is in your diff or in the hub.
