I'm rebuilding a 67 cj-5 and before anyone says anything I know this is a board for the cj-3B but this was the only place I found info on the end play for the Dana 44. The problem I'm having is I don't have the centering block that the axles hit in the diff and I was wondering if there was anyone out there that might have one or know the dimensions for one so I could make one.

Walton 1975,
Welcome to the CJ-3B Bulletin Board !

I personally don't mind the 3B related or the 3B sibling questions.
Actually I was planning to check that dimension because it's one rear axle factors that effects the OAW of the complete axle assembly.
I suppose this is for the standard open differential ?

Also I suggest that you post a WTB.

Early CJ's used 3 different center block spacers.
# 640965 is for 1946 to 1956 D41 and D44 with 10 spline axles.
# 649356 is for 1956 to 1970 D44 with 19 involute splines.
# 912637 is a 3 piece spacer for the 1956 and all later * Powr Lok differentials.
(*Jeep quit using D44 Powr Lok's in 1970 but some 30 spline Jeep rear axles are modified by using IH Powr Loks)

Your 1966 was standard with a tapered rear D44 having 19 splines.
A Powr Lok differential was an option.

Sorry, At this time I don't have any 19 spline differential center block spacers that I can measure.
I do have a Jeep racing friend that I can contact.
He likely has one available.

I can't thank you enough for all the info your giving me. That would be awesome if you could get me the dimensions!! Today I pulled the carrier out (with some assistance of a heat wrench to get the left axle out) and my problems went from bad to worse. It has a lockrite locker and the 4 pins that keep everything lined up were all broken along with the springs so while pulling the cross shaft out I noticed it was to short and has alot of play. I get the locker out and look to see what the damage is and its not good! The shorter cross shaft pin has elongated the hole though the carrier so now I need to replace the carrier too!! Luckly I was able to find a carrier at a local JY but it has the later year spider gears wont work with my axles that are 19 spline so i'm still stuck until I can get parts for the locker.

Technically speaking the "carrier" section is the cast housing portion of the axle assembly.
It is improperly yet commonly referred to as the "pumpkin".
Seems to me that you need a differential case.
I understand that you located a differential case for a D44 with 30 spline axle shafts.
Is that correct ? If so you will have to locate a 19 spline differential case.
I recommend either the standard 19 spline open differential case or a Powr Lok case.

Think we're talking about the same thing just using different terms.

Walton1975,

If I recall correctly, this is how the Lockrite is installed.....
The 2 standard pinion mate gears and the 2 pinion mate washers are replaced with the Lockrite unit. The center block spacer is not used.

Are you planning on replacing the Lockrite with the standard open carrier or what ?
Do you need the 2 pinion mates the 2 pinion mate washers and the center block spacer ? (total of 5 parts)

I had to look for Lock-rite instructions on line but it says the block is still used withthe lock-rite. You should be able to get one from Walck's I would think? smile.gif
