I figured this is best place for this question. I was rewiring my fence in the cattle field the other day, carrying posts through the mud in my truck. By the end of the day I got stuck.. I noticed my front wheels didn't pull as much as the rear wheels. In fact the rear driver side wheel seemed to pull the most. Is there anyway to make all four pull evenly?

 

Diff locks. Detroit, positrac, true-trac, air lockers. Your choice really (and wallet).

 

It sounds like you have open differentials in both the front and rear axles. I would at least install a limited slip diff in the rear, so once you lock the center, you have at least 3 wheel drive.

The front will require some careful selection, since something too aggressive will mess up steering. A good choice in the front would be a Torsen type differential (truetrac?), as it has the least tendency of all the designs to fight your steering efforts. It is actually an open type diff that provides more torque transfer than conventional diffs with spider and side gears.

By the way, "positraction", "posi" are GM's trade name for their limited slip differentials. Ford's are called Traction-lock or Equa-lock. You don't want to put a GM product in a Ford; it's sacrilege.

 

I think it is limited slip, it puts out two rooster tails when I run it in the mud. Just when it's stuck, all the power seems to go to the rear wheel that slips, and just a little power to the wheel across the axel

 

What do y'all think the pros and cons are between vacuum locks and electric locks? I know vacuum is easier to fix but my truck would need the whole system. Compressor, tank, lines, etc.

 

How old is the LSD in the rear? The stock setup is supposed to have about 40 lbs-ft of breakaway torque from the preload spring on the clutches. I've had to rebuild mine due to worn clutches. When I did it, I re-stacked the plates to replace one of the new steels with an old friction plate, and got it to work much better (and last longer) than stock.

Of course, the spring loaded clutches will not be as effective as a Detroit locker, or an electric or air locker. I would prefer electric, since all you would have to plumb is wires, vs air hoses, which will always leak, and it remains open until you need to lock it.
