sticky transfer box actuator

Hi
has anyone changed the transfer box electrical actuator on a VVT (2007)
if so is there a procedure?, it looks easy but not sure about any sinc-ing pitfalls do's and don'ts
any help would be greatly appreciated

I was all day trying to source a vacuum leak but its the actuator that is sticky once tapped with a hammer it functioned ok

new one costs £368 from Sims Suzuki and no redress kit available aparently
any pictures of the inside would be helpful as may go into this one

I had it out while i changed my gears inside the box.
Not sure if i have any pictures, but will check if needed.

The instructions for the gear wheel kit says it is smart to put the box in 4wd high before you start. It can be easier to get it back in if you do. Not sure if that is achievable when it malfunctions though..
Small tin lid on the actuator with three screws hides a small cog wheel inside you must remove.
Loosen and remove three bolts that attaches the actuator to the gearbox casing.
Unhook all wires, and wiggle the actuator until it slides off.
I never opened the actuator itself so i have no idea how serviceable it is but whatever is made by man can be repaired by man i have heard

reverse instructions to put it back.

If you have it in 4wd high when you put it back in, you can remove the plug on the front end of the case on the opposite side of the 4x4 light switch, remove the pin, and position the shift forks in the correct position at 4wd high to make it easier to reattach the actuator in the correct position.
You can check the position by inserting a small screwdriver into the hole of the pin and find the hole in the inner (long) shift fork.
The screwdriver will also stop the short shift fork from moving too far.
The screwdriver will also give you better control of the angle of the cog rod going into the actuator.

Also explained and shown in great pictures on the link below, but he did it in the 2wd high position:

thank you very much, I am a bit overwhelmed though, I was hopping it was a bolt off bolt on
If I remove the cover with the 3 screws is there anything that could fly apart ? as it could be shmoo in the cogs,
as a little tapping on that cover get is working again

Yakuza explained it well..

detailed step by step instruction for changing the gears, also covers removal of the actuator.

Nothing fly out when you open the cover for the actuator gear.
