check for power at switch power in power out if switch is good you have a bad actuator check for voltage first at actuator before youreplace

May be the problem is not in the actuator in the case but in the actuator that engages the hub locks . Check for vacuum line / electrical wires faults . The noise may be from the hub lock or from a cv joint in that side.

Check for the sensor on the transmission

It's either a vacum shift actuator, Rusty actuator cable, weak spring in side of the differential shift mechanism, TCCM (control module), switch, or vacum switch on transfer case ( start there). But all told, $980.00 in parts and $1200 in labor. Now take a deep breath as you call the tow truck to tow it to the junk yard.

I hava a 1999 Grand cherokee loredo V8 with full time 4wheel drive. when the rear tires slip I am hearing a poping noise in the front end when the 4wheel drive engages. I was told by one person that it could be the chain in the transfer case slipping but I was told by a jeep salesman that this year jeep did not have a chain. Could this be the CV joints in the front axels?

I have a 95 tahoe with same problem. Fuse was blown. After changing fuse kept bowing. Took apart electric actuator motor and it was full of water and burned out. Installed new one. Still wont engage. What is next steP?

I really doubt that its the spider gears that are bad. Most likely that its the axle shaft- not as bad as it sounds- I sell lots of them.

Most likely wheel bearing or cv joint issue. look for a ripped open cv boot. I believe that year used cv joints instead of regular u-joints. Hope I helped. Thanks
