bigger axles

What exactly is the difference between stock Dana 30 axles compared to the big 44s everyone seems to want? I'm just curious as to what exactly is "bigger." Are they thicker in diameter or what? Are they more powerful, and therefore better suited to offroading? If so, what makes them more powerful? Just checking. Thanks.

Re: bigger axles

the ring and pinoon gears are larger, the axles shafts them selves are larger, the axle housing and tubes are larger, the U joints are larger ( some later model dana 30s have the same ujoints though)

the knuckles readily lend themslelvs to High steering conversions, the gears and lockers are very common becasue a zillion vehicles used Dana44s

thats SOME reasons

Re: bigger axles

That page claims the YJ has a 5 on 4.5 pattern
The diamiter of an imaginary circle through the bolts right?
my Yj has a 5 on 5.5 pattern.
Does that mean the prevous owner did a conversion? or is somthing a-skew?

Re: bigger axles

5 on 5.5 is Ford half ton, and Cj bolt pattern.

most likely you arent measureing right, if you are then you lucked into a better axle

Re: bigger axles

Your YJ will have a 5 on 4 1/2" pattern.
It is measured from center of bolt to center of bolt, on opposite sides of the pattern.

Re: bigger axles

yeah that's right- the 4.5 bolt circle measurement describes the diameter of a circle that surrounds the wheel studs. you can measure from one stud to the one most opposite it and will read close to 4.5" even though you are not measuring exactly through the radius point.

you measure 5.5"? hmmmmmmmmmm

Re: bigger axles

Steve,
The diameter of the circle on a 5 on 4 1/2 bolt pattern would probably be a little over 5", as it would be centered on the arch between the two opposing bolts. Plus if you were to go to the out side of the bolts, instead of centerline that would add another 1/2". The correct way to measure is center of bolt to center of bolt. It will read 4 1/2"

i was just quoting from page 34 of may 2001 OFF-ROAD mag. it also has a chart which says if you measure 4-1/2 inch, the bolt circle is 4-3/4 inch. hey if he is measuring 5-1/2 inch between studs....hmmmmmmmmm that's not a jeep! must be one of them OOMPA LOOMPA MODS!

Re: bigger axles

take 2 stud next to each other, measure from teh centerpoint ( imaginary between the 2) to the far side fo the opposite stud

its hard to explain, I saw it in a cheesy 4by mag years ago, in fact maybe its measure to the inside..hmmm play with your own wheel ( knowing what the pattern is) and see

I thinkits between2 to teh outside of opposite one/
