school me on diffs

i have been rocking my 8.25 like nobodies buisness, but it's not happy. it's howling slams when you hit the gas, and once again when you let off. it's donzo. i'm looking at either a 8.8 or 44, whats the pros and cons of both. or maybe i'll do a dana 35

[clean4drxj]

both are good axles 8.8's are easier to find, have disc's and are strong yet have a weak stock carrier, XJ44's are bolt-in more aftermarkets available but can be hard to find and usual go for more $, it really depense on whats available to you for the best price.

[Cardinal]

also 8.8 has larger ring gear and larger 31 spline shafts vs 30 spline in the dana 44, but the 8.8 is a c-clip axle vs the 44 wich has bearing retainers that will hold your wheel in should you break an axleshaft, some 8.8 have a trac-loc wich is better than an open diff. dana 44 is bolt in too if you cant fab, there is a ton of aftermarket support with whatever axle you go with.

* 8.8 can be had with 4:10 ratio also, find a 4:10 front and its cheaper than regearing

Alot of people run the 8.8. You have to do a bunch of things to get it into a xj, like change it to a spring over perches, weld on shock tabs, set the pinion angle (a big advantage). I run the 8.8 without the lsd and welded tubes and it's strong, but not happy with it being unlocked. Another thing is that the 8.8 will prolly be about 1/4 inch on each side narrower than the stock rear, so if you're not running the right b.s, you might have to get spacers.

also if anyone knows where i can get one of these let me know

8.8
Benefits:
Larger ring gear
Thicker tubes
31 spline
Availability
Disc brakes
iirc runs same carrier for all gear ratios

Disadvantages:
c-clip but the rotor will hold shaft in if you break one
Less ground clearance
Not exactly Jeep width roughly 1 inch narrower
Not bolt in
flange



D44
Benefits:
Bolt in available if you have a xj
More ground clearance
Larger aftermarket support

Disadvantages:
Drum brakes
30 spline
smaller ring gear
Smaller tubes


both have huge aftermarket support

You're sure it's not just the backlash of the locker, Diz?

[Cardinal]

if you dont mind waiting i will have a 44 rear available in a month or too

Most junk yards got em', look for a 95+ exploder. got mine delivered for i think $250 from chuck and eddies

[konastinky1234]

i would highly recomend an 8.8. they're real strong, disc is nice, and the fab you have to do is not super difficult. i just put on in my tj this summer and it was a pretty big job for my buddies and i who are relatively unskilled in all of the areas that you need experience in to do the work. mine was about $222 to pick up at chuck and eddie's.

go 8.8 for the above stated reasons. thats all i got for ya. Fuck it, just get a Dana 35, wheel it till it breaks, then replace it with something stronger. D35's can be had for free and are disposable.
