High-Low Sleeve & Arm
WARNING: This page is about a different car, the 2003 Isuzu Rodeo Sport, 2003 Isuzu Rodeo, 2002 Isuzu Rodeo Sport, and 2002 Isuzu Rodeo. However, it is still accessible from the selected car via links, so may be relevant.
The spring standby mechanism is provided for the high-low sleeve in both directions of the high-low shift rod. For this reason, the rod position and the actual sleeve position may be offset in some cases.
This system is provided to protect the shift mechanism from the collision due to coincidence of the high and low phases of the engaged splines. By giving rotational force to the preventing phase coincidence, the splines are moved to the proper engagement position by the spring force.
