I have a 98 Z71 p/u, all stock, that the 4X4 suddenly quit. Was towing my CJ in the mountains, put it in 4 low to pull up muddy hill and front would not engage. As this truck does not have front hubs I'm not sure where to start. There appears to be an external actuator on front dif. Is this a solinoid to engage the front axles? If so is this a part that commonly fails? Another unusual symptom is that in drive/low range the auto trans would not up shift, it would manually shift to 2nd but not 3rd. I would appreciate some advice and/or a link to a trouble shooting/repair guide. Tried a search, no joy. I appoligize in advance if this is a commonly addressed problem on this BB. I'm ussually found on the Jeep SWB BB. Thanks.
Did the posi-lok on my '98 S-10. Cool little toy, and more-or-less easy to install. Not planning on doing anything to my '98 Full Size until the damned warranty runs out! [img]images/graemlins/censor.gif[/img]
