Rubicon D44 Axle Shafts, Lockers and Upgrades?

[Benito]

I have a couple of questions on stock rubicon axle shafts, lockers and future upgrades. My rear factory locker has died, it has what i suspect an internal fault that causes the fuse to blow which doesn't allow me to use the front locker, for now i have disconnected the wiring harness for the rear locker from the relay so that i can continue to use the front locker.

What i know is that the stock front axle shafts are 30 spline and that the rear axle shafts are 32 spline for Rubicon axles, also the rear axle shafts are different sizes. i paid a visit to the ARB website and saw that they have a RD157 option that require 35 spline axle shafts for Rubicon housings, i believe i was told by Wes at trail jeeps that this locker would fit in my PR44 for factory locker.

my questions are:

1) does the RD157 locker fit in the front(PR44) and the rear(stock) axle housings?

2) do more splines = thicker, stronger shafts?

3) since new shafts would be required for the rear, would the new 35 spline shafts be of equal length?

4) what other options are there to replace rubicon lockers?

thanks in advance!

I don't think so. I have an RD147 up front in PR44 and an RD157 in the rear stock D44. Both are 35 spline but RD157 fits the Rubicon housing.

The RD157 fits both front and rear Rubicon axle housings

2) do more splines = thicker, stronger shafts?

The shaft is larger where it goes into the locker but necks down to the stock size after a few inches

3) since new shafts would be required for the rear, would the new 35 spline shafts be of equal length?

The 35 spline shafts needed for the RD157 are the same length as the stock - that is, they are not equal in length

4) what other options are there to replace rubicon lockers?

As far as I can tell (and I've looked everywhere I could think of), there are no other options

Thanks for the replies

Did you have a D44 in the fron prior to the upgrade? they make two different housings, one to accommodate Rubicon internals and one to fit regular D44 internals.

thanks, this clears everything up a bit. i know that RCV make the 35 spline shafts for the front and rear for this application but are there any alternatives?

Maybe try asking G2. They have 35 spline shafts for their core 44 application that may be the correct length.

I have a set of Nitro 35 spline rears that have worked out great so far. I also think revolution and dynatrac make them as well.

Before spending all that money look into replacing the solenoid. It's really the only thing that can fail on the locker internally and a hell of a lot cheaper than doing all that ($200).

This is probably the route I'll be taking. I didn't know this was possible until I saw this thread ( http://wayalife.com/showthread.php?40060-JK-Rubicon-Lockers-Serviceable ) pop up yesterday and someone posted a link to the part.

If your planned repair doesn't work out I recommend sending Dynatrac an e-mail for pricing on a Trail60. Last time I looked it wasn't that much more than replacing the locker and shafts (with labor) and to me I'd be a much better route.

Keep in mind that your flanges will still be a weak point on the Trail60.
