Oldsmobile Questions? Ask a Mechanic for Answers ASAP
if you remove the front driveshaft from the transfer case to the front axle will it stop doing this ?
yes to just road test its safe too
usually if it stops doing it with the axle out its the fluid in the transfer case or the transfer case internally
if its wrong or dirty the transfer case clutches are chattering causing this issue
yes there is a drain and fill plug right on the back of the case
use autotrakII fluid'
it should take close to 2 quarts to fill it
drain it out and fill it up and see if it gets better
how are you making out ?
