If you dolly it you put wear on the wheel bearings and ring and pinion in the differentials on the front or rear depending on what axle you raise.

you have to remove the cover then spin the carrier assembly by spinning drive shaft un till you see a mall bolt that will hold the pin in that runs through the center of the carrier remove bolt remove pin push axle shaft in so that c clip can fall out with c clip out remove shaft when re installing push axle in all the way put c clip in and pull axle shaft out word and reinstall pin bolt and cover.

There is no electric solenoid set up for the S10's, the upgrade was for the full size SUV's from the early 88 to 98 that had a thermal actuator. There is a mechanical system that is made for the S10's but it requires drilling a hole through your fire wall, running a cable into your cab and mounting the cable lock somewhere under your dash for easy access to lock in your differential.
I had the same problem and i just locked up my front differential all the time, it's been like that now for over 10 years without any issues. The transfer case is not locked up so your front axle is still not synced with your rear axle and is still free to rotate at a different speed then the rear. Just make sure you service the front differential like your suppose to and you should be fine on running with the front differential locked.
Thank you for using fixya and check to make sure that there is no cracks i your vacuum line that is keeping your front actuator from functioning or a failed vacuum switch on top of the transfer case.

most axles fill plugs are located on the rear cover just fill until it starts coming out and your done. on some axles there will be a plug on the axle itself located on the fron side of the housing close to the driveline

the bolt on the cv halfshaft but sounds like you lost a wheel bearing if you loose the bearing the shaft can pull out

pull the rear cover off the diff, then remove the center block from the gear carrier, there is a single pin in the side that lets the block and cross pin come out, the push the axles in and remove the "C" clips retainers.

On the rear axle.
