Oh, and Explorer leafpacks can also work. They sit a bit lower than even 2wd MJ packs. But you must reuse your MJ main leaf and re-drill it to accept the slightly larger Explorer center bolt.
4wd MJ on the left, 2wd in the middle and Explorer on the right:
Not that I know of. By this point in time, the condition of the leafs matters a lot. I swapped out my old rusty 2wd leafs for a rust-free pair from FL and got an inch of lift. :dunno:
While we're on the subject, to help battle the springwrap I added a second MJ main leaf to my packs by cutting off the eyes and placing it directly below the main in the new pack.
I believe I saw it on "Extreme 4x4" the tv show. Essentially, you pull out the 3rd member, gut the housing, pull off the knuckles, flip the housing to become a drivers side drop, then reassemble. If you say it fast enough, it almost sounds easy. :D
Checked the engine block ground? Just a thought.
I also had a super rich condition in my 86 (carbed, so I don't know if it really correlates) due to a weak connection at the coil (the wire that feeds 12volts to the coil). The weak spark wasn't burnign all the fuel in every cylinder. Eventually I blew up my muffler while trying to diagnose it. :D
4.10s work just fine with 31s on the highway. :thumbsup: I've got 3.92s and 28" tires in my Dak R/T. The lowest possible rpms don't necessarily translate directly into better mpgs.
