HELP 1991 wrangler 4wd jumping
 

Hello, I have a 91 wrangler i have owned for a few weeks, we took it
in the mountains for the first time last weekend first time to "test "
the 4wd, in high range it acts like it 'slips' for a fraction of a
second every 100 feet or so on snow or ice, it doesn't do it in low
range, just in high, also, it is difficult to get into low range.. any
ideas ?? Help..

thanks..

First, realize that the reason for restricting 4WD to loose surfaces
is so that the tires CAN slip. This is especially noticable in turns,
but it occurs all the time since there is no way to keep all 4 wheels
turning at exactly the same rate. It will be more noticable if one or
more of the tires is worn more than the others or if you have mixed
brands on. The 4HI slip may well be the shift linkage just a little
out of adjustment - you adjust it by setting the clamp on a rod just
forward of the transfer case. Those do slip and let you wind just
barely in gear, but if it goes back in by itself it's probably normal
ties slippage.

As for 4LO, it's going to be a bear at times. You need to just be
rolling - like a slow walk - as you shift in/out. Even then it can be
a challenge to shift without some grinding if you have an auto
transmission. I usually get just barely rolling then SHIFT. Don't
monkey around or baby it, use a good firm shift. That will get you a
clunk instead of the coffee grinder effect.
