Hi all.
Got a few problems that I cant suss out and I thought somone here might be able to help.

To start with it is stuck in 4wd high and when i go into 4wd low the lever wont flick back up and pop out. has anyone had this problem any ideas?

secondly there is a rumble type vibration when i first pull away. i cured it by putting on freewheeling hubs, which has solved the problem on the road for now. could it be the front diff. I have a spare axel so im going to swap the diffs over today. Hopefully that should cure it. but any ideas on that would be much apreciated.

Thanks all Nick
