Re: ABS vs Part-Time 4x4 ?
Yes, it's a true part time 4x4. (I also have Full Time 4WD also.)
The 2004 GC Laredo still come with it. Limited/Overland do not. In 2005
Jeep does away with Selectrac all together for GC.

Re: ABS vs Part-Time 4x4 ?
In my opinion you should pull the relays when you are in 4x4 or there
should be a switch. ABS is only good for dry pavement. See Bill's
link... I also have seen a bunch of ABS vehicles calmly just keep on
going totally out of control until that tree finally stops them. On the
street in snow, that would be another vehicle or power pole.
The collision fixing folks must just love ABS come winter. LOL!
If you have the owners manual for your Jeep, it should warn you to stay
off the brakes in the snow. Both my manuals state to use the gears to
almost stop, then hit the brakes. The gears can hold you at the
'threshold' braking point really well with a little practice.

According the the brochure I received with my TJ MIke, a TJ's ABS is
disabled at speeds below 5mph.

Re: ABS vs Part-Time 4x4 ?
That is fine except when you are doing 6+ mph and hit the brakes. The
ABS kicks in and stays on until you let off the pedal or roll to a stop.
(or tag the tree)
If the ABS magically turned off as you slowed past 5 mph, then you could
lock the brakes and stop. It sure doesn't appear to do that because the
wheels 'don't' lock.

Re: ABS vs Part-Time 4x4 ?
That is fine except when you are doing 6+ mph and hit the brakes. The
ABS kicks in and stays on until you let off the pedal or roll to a stop.
(or tag the tree)
If the ABS magically turned off as you slowed past 5 mph, then you could
lock the brakes and stop. It sure doesn't appear to do that because the
wheels 'don't' lock.
