GENERAL DESCRIPTION

M1251000100119

The MONTERO has two propeller shafts. The front
propeller shaft connects the transfer case to the front
axle, and the rear propeller shaft connects the trans-
fer case to the rear axle. Each propeller shaft is a
two-joint type propeller shaft, and they have the fol-
lowing features.

• A snap-ring method of securing the journal bear-

ing of the universal joint has been adopted.

• The CFRP (Carbon Fiber Reinforced Plastic)

tube equipped with a shock absorbing mecha-
nism (contraction) improves safety in collision.

If an abnormal noise is heard from the propeller shaft
while driving, some parts of the propeller shaft may
be worn or damaged, or some mounting bolts may
be loose.
