More On My Rear Dana 44....

So..... When I discover that's the problem , I'll need to order a thin ring gear from the gear guy ? I seem to be going backwards on this install …….

UpDate : There are no such thing as Thick or Thin Ring gears ....

 

Compare you two cases side by side as shown above.
Are you changing the gear ratio ?

 

No , I'm reusing the existing Ring & Pinion. I previously measured each one, end to end, & they are the same ? However , I have not compared them side to side ? I'll try to do that later tonite. Thanks.

 

Yes James,
I went ahead and already pressed the bearings onto the Trac-loc case...... WITHOUT shims I've revisited my TSM & your advice . I have ordered a shim kit from Randy's. I am about to order new Timken's for the Case, because I'll most likely damage them on removal ? If I don't , I could ream them out & use them for set up ......... Like I was supposed to in the first place. I can't tell you guys why I jumped the gun on this....... Maybe ' Cuz of the cold & waiting on getting this job done ? Now it has cost Me !!!
Thank you all for your advice & patience. I messed this up & I am better than that.....It's embarrassing to say the least !

 

Thank You James,
One MUST follow procedure 1st & tricks of the trade 2nd. I appreciate that very few of us are certified CJ5 technicians, so it's more important than ever to heed carefully , our other member's experience . Also , of course, The TSM......as timgr has often said! I will post those pic's after our next storm system passes..... most likely by Sunday.
I do have a fair knowledge of brake systems , although my recent work was Rebuilding my ' 75 with a GM Hydroboost system. All brake systems are very similiar , from the MC to the wheels. If I can be of any assistance, please reach out. BTW, I did recently struggle with some bad parts , so now I can point out Whom to use & what to watch out for.
Peace,
Richie

 

This is bothering me...…. I'll have those pic's up in a couple hours...……..

 

So.....Ryan is was correct. My '75 case is a Series 3 & I purchased the wrong case.
Also, James & Jeff were correct . My existing case had 2) .30 shims on the ring side & 1) .30 shim on the right side , under the bearings.
Well, Here they are :




The OEM case 's deck height is 2.152 & the new Trac-loc is 2.472 about 7/16 to 3/8 difference. I wish I could just run a thinner ring gear.

Thanks for all your guy's support in this lost cause.

 

My lifelong mantra: “Accept it and move on.”

 

Thank you, My Brother's in Arm's.........Instead of biting the bullet , I was ahead of you. I took a a double bite of Jim Beam mydamnedself.

 

May be a stupid question here : Do you guys think that I could swap out the side gears , clutch packs & spiders from my series 4 case to a new series 3 case ? I can get one , new , for 40 bucks ?

 

This is key to keeping stress at a manageable level.

 

So..... Besides Maker's Mark or Beam , for medicinal purposes only, I'm looking at the Auburn Gear Professional LS. Fairly decent price. More research on this 50 year old Company to come ?

 

So what gear ratio are you trying to run? What spline count are your axle shafts?
I may have a low mileage take out D44 TracLok if it matches what you need.
I kinda warned about opening a can of worms!

Thanks Donny,
Yes you did, my Friend. It started when I realized I got Ripped off. I was led to believe that I was buying a Series 3 case. Happy -go - Lucky here , thought I could just R & R , while also just installing new case journal bearings & cones's.
Anyway , I 'm running 3.73 gears in both , with 30 spline rear , 27 spline front. I do have a Series 3 case coming today. I'll swap in the side , spider's , & clutch packs from the one I bought previously. They are brand new, just in the wrong case for my Jeep.
Thank you for this offer & your knowledge , though.
Richie

 

Got the wrong case gutted this morning . Waiting on arrival of correct series case.
Oh....btw, I just noticed........ The clutch's are soaking in additive, not STP ! I use that for assembly sometimes.

 

Ok, I about give up here ........Dd the clutch R & R plus the gear swap into the new case , by the Book. I cannot turn this differential ? I have an axle shaft mounted in my vice & set the case on that...... Can not move the gears , with a large bar, At ALL?

What have I done wrong , BESIDES the Obvious ??????

 

Probably nothing. You shouldn’t be able to turn a newly rebuilt clutch-style LSD by hand.

Keep in mind, the axle sees thousands of lb/ft of torque. You’re trying to turn it with maybe 100.

 

Thanks, Ryan........Time to bolt it in then ?
I'll get that done on Sunday & let you all know.
