Re: One rear wheel spinning on XJ
Thanks for the info folks, I guess I was expecting a little more traction
than I'm getting; I'll try the braking trick, sounds excellent! I just moved
to the snow, and I've been driving my rear-wheel drive car around, and I
expected the Jeep to have at least that much traction in 2wd...but I suppose
the rear end is pretty light. What worried me about it is that before I
bought it I didn't know about the difference between Command and Select
Trac - I thought all Jeep 4x4's had a differential between the front and
rear axels. My concern has been when you are driving on a snowy section
you'd have it in 4H, but then if you hit a bare patch you have to shift it
to 2H so as not to wind up the transfer case. I'm sure I'll just get used to
it. It's old but in excellent condition, I'm going to order a 2-3" lift kit
and put maybe 31" tires on, I can't wait to use it up in the Rockies! Thanks
again,
Bob

Re: One rear wheel spinning on XJ
Good point about reverse pulling it down, I had forgot about that. I just
always think of reverse as a higher ratio than 1st, which was why it didn't
make sense to me. I'd love to leave it in 4wd on the roads here, but there
are so many bare patches mixed with ice here, after reading posts about the
Command-Trac I'm worried I'll blow the transfer case out on the first one I
hit. I know you can shift on the fly but is it bad to keep going back and
forth at city speeds?

Re: One rear wheel spinning on XJ
No issues using 4x4 just like any other shift, I do it all the time
around here.
Going straight also isn't hard on Command Trac, it's turning corners on
dry that causes problems so hitting the dry and waiting or needing a
minute before shifting back to 2 wheel drive isn't an issue.
You also might want to use 2 wheel drive at intersections if you plan on
turning. If your tires are too wide, they will get up on top of the
snow and float and it will want to go straight.
I made a mistake and put too wide of tire on our Cherokee. I went up to
a wide tread BFG AT P235's and they handle very poorly compared to the
skinny tread Hercules Terra trac P225's we had on there before.
All brands are not equal for tread width. The BFG's are a 'lot' wider
than some other brands of the same size.
Same deal with our two Jeeps. My tall skinny mud tires can run circles
around my wide AT tires in the snow.

dry that causes problems so hitting the dry and waiting or needing a
minute before shifting back to 2 wheel drive isn't an issue.
You also might want to use 2 wheel drive at intersections if you plan on
turning. If your tires are too wide, they will get up on top of the
snow and float and it will want to go straight.
I made a mistake and put too wide of tire on our Cherokee. I went up to
a wide tread BFG AT P235's and they handle very poorly compared to the
skinny tread Hercules Terra trac P225's we had on there before.
All brands are not equal for tread width. The BFG's are a 'lot' wider
than some other brands of the same size.
Same deal with our two Jeeps. My tall skinny mud tires can run circles
around my wide AT tires in the snow.

Re: One rear wheel spinning on XJ
No issues using 4x4 just like any other shift, I do it all the time
around here.
Going straight also isn't hard on Command Trac, it's turning corners on
dry that causes problems so hitting the dry and waiting or needing a
minute before shifting back to 2 wheel drive isn't an issue.

Re: One rear wheel spinning on XJ
Hi Bob,
Be very careful with the braking trick or this might happen to you:
http://geocities.com/snatchbuckle/
It got me unstuck a few times, but I had to learn the hard way not to
overdo it.
Don't worry about frequent 2HI/4HI shifts at any legal speed. Remember
that windup is not an issue on straight sections. If the bare patches
are in the minority, the drive train can unwind when you're back on the
snow.
