Outer Limits 4x4 Board

Hi all,
I've got an '81 HJ47 with low k's.It runs like a train but the transfer shifter has a vibrating noise.When I put my hand on the top the vibration/noise stops.The transfercase works fine and is not noisy when in operation.
Can anyone tell me what might cause this and how can I fix it?
Any help appreciated.
Cheers

There would be bushing where the linkages go from the shifter to the case. Maybe these bushings are busted. Would take two seconds to slide under and wobble and shake a few things.

thanks mate, I'll get under in the morning and check it out

Easy fix is to keep your hand on it

As stated above climb under and check for any movement. There are a couple of plastic bushings that may need replacing.

thanks Ruff, I'll let you know what I find.
