Re: How do I replace a front left wheel bearing on a 1998...
Check this prcedure for GM truck about Front Hub, Rotor and Bearings - REMOVAL & INSTALLATION
Raise and support the front end on jackstands.
Remove the wheel.
Dismount the caliper and wire it out of the way.
Pry out the grease cap, remove the cotter pin, spindle nut, and washer.
Remove the hub. Do not drop the wheel bearings.
Remove the outer roller bearing assembly from the hub. The inner
bearing assembly will remain in the hub and may be removed after prying
out the inner seal. Discard the seal.
Using a hammer and drift, remove the bearing races from the hub. They are driven out from the inside out.
To install:
Clean all parts in a non-flammable solvent and let them air dry.
Never spin-dry a bearing with compressed air! Check for excessive wear
and damage.
When installing new races, make sure that they are not cocked and that they are fully seated against the hub shoulder.
Pack both wheel bearings using high melting point wheel bearing
grease for disc brakes. Ordinary grease will melt and ooze out ruining
the pads. Bearings should be packed using a cone-type wheel bearing
greaser tool. If one is not available they may be packed by hand. Place a
healthy glob of grease in the palm of one hand and force the edge of
the bearing into it so that the grease fills the bearing. Do this until
the whole bearing is packed.
Place the inner bearing in the hub and install a new inner seal, making sure that the seal flange faces the bearing race.
Carefully install the wheel hub over the spindle.
Using your hands, firmly press the outer bearing into the hub. Install the spindle washer and nut.
Spin the wheel hub by hand and tighten the nut until it is just
snug-12 ft. lbs. (16 Nm). Back off the nut until it is loose, then
tighten it finger tight. Loosen the nut until either hole in the spindle
lines up with a slot in the nut and insert a new cotter pin. There
should be 0.0012-0.005 in. (0.03-0.13mm) end-play on R-series and
0.001-0.008 in. (0.025-0.200mm) end-play on C-series. This can be
measured with a dial indicator, if you wish.
Replace the dust cap, wheel and tire.

That is what the pushbutton control on the dash is for. As far as a front end conversion is concerned, really no practical way. You could swap it for one from a two wheel drive S10, but that will also involve changing the transmission to one without the PTO and modifying the control circuits..
By removing the drive line you may move the car but it will lock up on you at some point,, the rear end, wheel bearing or broken axel will cause more damage, just tear into it and fix the problem before it causes you more trouble.....Hope that helps...
Did you recheck to see if you plugged the speed sensors back in. The speed sensors are built into the wheel bearings on the 4wd models. If you did plug them back in, then one of you new sensors might be bad.
What part do you want to take out? if it's the pinion bearing you have to remove the driveline remove the pinion nut pull the yoke off pull axles out and remove bolts to get to the inner bearings and the 3rd member bearing cap 2 bolts on each side.
Check the ft diff actuater. Sounds like the ft diff isn't complelely disengaging when in 2 wheel drive. Also I'm not sure but I think that the fr driveshaft should not be turning when in 2 wd. If it is turning then you could have a problem with the transfercase.
Thank you very much.The video really helped me a lot.
