I have a 1995 Chevy Suburban K1500 4WD with 234,700 miles. When it is in 2WD it seems like the front axle is dragging or somehow in a bind. If it's put into 4WD (hi or lo) the dragging is even worse. Usually when you back up to switch from 4WD into 2WD, you can hear a clicking noise when the hubs unlock. There is no clicking noise and the hubs seem to stay locked up. Do you have any suggestions as to what might be causing this problem? :? Thanks in advance for any advice.

The 4wd actuator might be stuck in the locked position.Regardless of where the t-case is the front is locked in.GM had quite a bit of trouble with those.The updated part has a heater circuit and other upgrades.

Suggested Repair

Inspect the front 4WD actuator, which may be stuck in the locked position so the front axle stays engaged regardless of transfer-case selection. GM had problems with these actuators; the updated replacement includes a heater circuit and other upgrades.

Backing up to shift out of 4WD produces no hub-unlock click, and the hubs appear to stay locked. The expert said the 4WD actuator may be stuck locked, a known GM issue, and noted that the updated part adds a heater circuit and other upgrades.
