locker advice
I have a 97 Wrangler, lifted about 4 inches with 33x12.5x15 tires. It has
3.73 gears in a front dana 30 and rear dana 44. It is an almost daily driver. When I take it off-road, it is mostly mud with a few rocks every now and then. Both diffs are open. I would like to lock up both ends or at least the rear, but the situation I found myself in (deep muddy ruts) the other day, I could not get out of the ruts because of the open diff. The tire up against the rut wouldn't spin while the other side spun freely. Not a great situation. Ok, I digress, I would like to install lockers, of some sort, at the same time as re-gearing to 4.56 or 4.88. My questions are these: 1. Will these diffs handle those gears? 2. Any recommendations or opinions on the Detroit TrueTrac, Electrac, or Locker? 3. I would like to stay away from friction additives and the Auburn limited slip sounds like a pain if you have to send it in for rebuild. The article in the recent JP magazine is what swayed me towards the Detroit brand. Also, how hard is it really to install new gears and lockers at the same time? Thanks, Dennis 97 Wrangler |

Re: locker advice
For best traction in a daily driver, a locker (no-slip) is preferable to
a limited slip like the TrueTrac. The one that gets the raves for durability is the Detroit Locker. It unlocks automatically when turning on high traction surfaces. Does winter street driving involve snow where you live? If so, an auto locker may be unsuitable. It will stay locked on a slippery road and pull sideways to the ditch. Consider a manually selectable locker like an ARB air locker, Electrac or OX locker. Alternately go for a good limited slip like the TrueTrac. If snow is not an issue, the Detroit Locker is good, but there are less expensive and easier to install 'lunch box' automatic lockers like EZ Locker or Powertrax/Lockright. These replace your side gears and spider gears using your existing carrier with no need to touch the ring & pinion. If you do go for one that replaces the carrier, then it is wise to do your gears at the same time. Doing your own gears is possible, but you'll need to do alot of reading, invest in some special tools, and block off at least a day to get it done. http://www.differentials.com/install.html http://www.thedirtforum.com/differential.htm http://www.motivegear.com/tech_info/...tructions.html It ain't rocket science, but you do need a good grasp of how to measure and adjust pinion depth, backlash, and bearing preloads. It can take many time consuming cycles of tearing down and reassembling with different shim combinations to get all the variables within spec.

Re: locker advice
I will second or third the snowy roads warning. They call lockers 'low
side finders' and they have no manners in snow. Other than that, here is a trick for you that dates from the first vehicles made. I have been 'stuck' on slush with an ice base and had 2 wheels merrily spinning away, one front and one back, so the boys are going for the straps.... Suddenly bang, I have all 4 tossing rooster tails and away I go! The boys are sitting there with jaws hanging.... If you hit the brakes while popping the clutch, you will load up the wheel spinning so the torque builds up high enough to break the 'stuck' wheel free and you have both tires spinning. The owners manuals for 'both' of my Jeeps say you can load up the rear by putting the emergency brake on to get both moving, but that hasn't worked for me, using the brake pedal works quite well and if you get it just right, you can load up the front at the same time to get all 4 spinning. The diff puts 'equal' torque to both wheels. The one free spinning needs almost 0 torque to spin, so the stuck wheel sees the same almost 0 torque. Use the brakes to raise the torque needed to spin the wheel, and the other side sees the same raise in torque. Get high enough, and the stopped wheel 'will' break free. It takes a pile of practice, but it works well.
