Re: 4x4 activation problems
Is the 4x4 light coming on in the dash?

Re: 4x4 activation problems
Ya, we need more info. What do you mean by lock and what is it your expecting to happen when you shift that that thang. People have different interpretations of what locked means.....jj

Re: 4x4 activation problems
all the 4x4 trucks from 90 on all have automatic locking hubs. so it is either going into 4wheel drive or not. when you shift it into 4L the xfer case may ingage the transmission but may not be engaging the front drive shaft.. if that is the case there will be an issue with the xfer case. $$$

Re: 4x4 activation problems
There hasn't been a locking hub on a 1500 series since 1987. These use a central axle disconnect.
