Hi,Need some help to ID this problem. I have a 2001 3.2 manual SWB Pajero. I was driving in H4 and when returned to 2H started hearing a noise that sounded like a actuator trying to open or close from under the dash or floor (not sure exactly

), this I only hear whilst driving in 2H, while stationary no noise.
Hope can assist me!
Regards
Derek
