A few years back when I had money to put into the Jeep, I had ARB's installed front and rear when I regeared.  Made a big difference when crawling.  With the lockers I was able to creep where others took the "heavy foot" option.  I did put 4.10's in when I regeared, but have regretted going with those.  Would like to gear again with 4.56 or 4.88's.  Not sure which ones yet, but I too run an auto.  The 4.10 were an improvement, but with 33's, they weren't enough.  Think I can get more power on the road and better gas milage with another gear change.
