Re: ABS vs Part-Time 4x4 ?
And if I had ABS I'd disable it when pulling my boat/trailer ... geez ...
I'd be clicking my way through every stop sign/light I encountered.

Re: ABS vs Part-Time 4x4 ?
The first time I saw the Antilock Brake System was on a mid sixties
International Harvester Travelall that worked the rear axle only as part
of their trailer package.

Re: ABS vs Part-Time 4x4 ?
That makes sense (to me) for that type of vehicle ... would prevent spinout.
OT: I have fortunately on only one occasion had to brake or else with the
boat/trailer ... all 4 jeep tires were smokin I tell ya (why I keep my
brakes/tires in good shape). Ok, I admit, trailer brakes would be the smart
thing to do ... next time for sure.

Re: ABS vs Part-Time 4x4 ?
Who knows why those Jeeps just kept rolling. Short of tearing them apart in the
field to test for failure we'll probably never know. When I first got my TJ I
was leery of the ABS given the problems I had with the GMC. So I carefully and
safely tested it while the Jeep was stock. Had it done anything I considered
unsafe the fuse would have been pulled in a heartbeat.
The other possibility is that Jeeps come with varying build qualities, some
good, some lemons. You could have had two lemons. If the lemon theory is what
happened it doesn't make ABS bad. It makes DC's quality control suspect. And
to suspect something as critical as a braking system scares me.
Personally I do know that all ABS systems are not created equal. My BMW had the
best system I've ever driven, the GMC was just dangerous and my TJ is someplace
in the perfectly acceptable range.

Re: ABS vs Part-Time 4x4 ?
Who knows why those Jeeps just kept rolling. Short of tearing them apart in the
field to test for failure we'll probably never know. When I first got my TJ I
was leery of the ABS given the problems I had with the GMC. So I carefully and
safely tested it while the Jeep was stock. Had it done anything I considered
unsafe the fuse would have been pulled in a heartbeat.
The other possibility is that Jeeps come with varying build qualities, some
good, some lemons. You could have had two lemons. If the lemon theory is what
happened it doesn't make ABS bad. It makes DC's quality control suspect. And
to suspect something as critical as a braking system scares me.
Personally I do know that all ABS systems are not created equal. My BMW had the
best system I've ever driven, the GMC was just dangerous and my TJ is someplace
in the perfectly acceptable range.
