Exclamation Fake Dana 44's?

I just found this page through google: Here.

Quote:
STOCK "Dana 44's" front and rear (note: these are not TRUE D44's!! They are D44 covers with Dana 35 and 30 shafts)


There's no way that can be true, right? People throw huge tires on there and don't break anything.

LOL

They are real 44's. The 44 part is the center section.. From there yes the axle tubes are about the same thickness as the dana 35/30. The spline count are as follows:

TJ wise
dana 35 27 spline rear
dana 30 27 spline

Rubi 44 front 30 spline inner axle 27 spline outer
Rubi 44 rear 30 spline

yes. the number of the splines is different. the axle shaft diameter and strength is the same in a front D30 or front D44.

thatīs why I donīt care about my stock axle shafts with the 35s.

Do you have the D44 in the rear?

I am fairly certain the inner shaft is a bit thicker hence the 30 splines, outer the same.

the tj D44's have the thinner axle tubes (like the D35 axle tubes)
the older D44's (like the xj/mj) have thicker axle tubes

the front rubicon D44's are the D44 housings and D30 outers

kinda like the diamond axle you can order the housing to exept the 9" center (or high 9) with a D60 outers

But are the rear axle shafts stronger?

the shafts them selfs no they are the same (unless its a rubicon D44)
just the tubes are more prone to bending on the tj

if you want the shafts to be stronger then you need to look at the alloy's
or the bigger spline alloy's

I'd tend to disagree on this one. There is an increase in the rotational strength or degree of twist from the 27 spline to the 30 spline. However the outers are exactly the same between the two axles.

i would be will to lay a d30 shaft next to a 30 spline d44 shaft to prove you are wrong....the d44 shaft is bigger whether it is rubicon, ford, chevy or dodge...they did not make a special smaller diameter/weaker 30 spline inner shaft for the rubicons......they are a big upgrade other than the outers......also the rear axle is just as strong(other than the axle tubes) as any other d44 rear ever made......whcih most were put in jeeps and had small axle tubes any way....compare the tube wall of a tj 44 that barely makes it to 3/16ths to the ford 44 that i run with a 3/8s tube wall thickness.....doesnt seem that important but if those tubes flex then you break axles....the jk 44 is the way to go if you want some strength in a d44 upgrade

What do you think?
Is it a good idea to upgrade my stock 27-splines axle shafts with some chromoly 27-spline axle shafts? I donīt want to waste my money.
I donīt want to buy a new 30-spline ARB locker...

You have a Dana 30 in your TJ currently correct? Yes I agree that you wouldn't want to spend the money on the ARB all over again. So upgrading to some Chromoly 27 spline shafts will increase the strength of your front end.

Yup, that's what you'd need. I know that you are kind of stuck with using 4WD Hardware because of the shipping issues. Unfortunately with the issues with Alloy USA right now and the fact that 4WD doesn't carry Yukon Axles that's about the best you can get. They do sell Warn axles also, but Superior's should do for your purpose.

Nothing wrong with the parts, but the company has went out of business in different stages. There are a few different companies that are bringing the brand back currently, but I haven't seen any product being shipped from them yet.
