The Super 35 won't work for the Wj. It does however work very well for those of us who use them.

I have a 1999 wj from early in the year of production.
I had Diff noise and brought it in to Minot Motorworks in Marshfield, MA and they have "fixed" it twice. The hum goes a way for a little while then comes back. This most recent time it only Hums at certain speeds. Every time I talk to the guy he says "it's jeep" "jeep sucks" others just say the 99 wj has a bad diff. Wouldn't that have been taken care of if it were "fixed"?
Well I know the jerk has been ripping me off and that is why I have started doing my own work, at least the very simple stuff. I would sue but I don't really want to mes around with this hack, If he can prey on poor people like me, he probably has a way to defend himself.
I am hoping to start improving the drive train then lifting the WJ a bit.
What should I do about this Diff problem? I was thinking about a swap because that "swap-ability" is what I love about jeeps. I'm broke and I won't have the ability to rebuild the one that is in it now so I think it would be best to get one that is ready to go.
What would be the smartest most plug and play swap for a better rear end?
the D44a is the easiest swap from the D35c, and if you have a D44a, the D35c swap is the easiest What axle do you have right now? In your sig post the stats on your Jeep (Year, Model, Engine, and Transfercase). Putting in a Ford 8.8 is the most popular alternative axle I have seen used. It isn't just plug and play though, as far as I know (AFAIK) you have to weld on some mounting brackets for springs/shocks etc..
The D44a is a strong axel. It is the same as the reg D44 only it has an aluminum housing. The only bad thing about running this axel is there is no locker for it. But if you get one from a WJ with quadradrive it will have LSD. Also it is a direct swap becuase it is from a WJ...
If you dont plan on using 4wd then you dont have to worry about it. But like most of us use 4wd then yes you would have to get the front regeared. You could technically use it in really heavy muck b/c you wouldnt be getting any traction but as soon as you get good traction on both back and front your in trouble. Think about it this way your wheels would be going at 2 diff paces and if thats on an ideal traction surface then it def wouldnt be a good thing.
