Replacing the clutches in a Dana 44 Power Lock is pretty easy. There a just a few simple rules to follow. Email: support@5speeds.com Web: www.super661.com
Let me just say WOW. What a find on RUclips! You are a first-class builder. Someone who takes pride in their work! Getting ready to build a ford top loader. Subbed.
Thanks for posting this Paul. It gave me the confidence to replace my own clutch pack. Is there a chance you can suggest how to test the breakaway torque? I clamped the whole case in the vice and inserted the driveshaft end with a torque wrench on and it wont breakaway - tried up to 100 ft lbs and dont want to go further and cause damage. I arranged the pack as you stated, so tried re-packing with a disc missing each side and confirmed it works (disk pressure causing it to lock) so my test initial test must be floored in some way. Any suggestions how to test?
Great video as always, thank for sharing......got a bit an off-topic question: have you ever seen a Warner 10-10-024 Industrial transmission, it's a single speed forward-reverse with a torque converter, used in a forklift from the 1970s. II cannot find a manual/drawings or parts for it here in the UK, and on Google, this thing does not exist either. Don't even know pressure figures and port locations, any help would be much appreciated.
I found it makes no difference. I do lube them and I do not get any clunking or chattering issues. Sometimes using the wrong oil creates more chattering issues.
The Dana 44 in my CJ5 has a Trac Lok diff if I'm not mistaken. It doesn't seem to work anymore even with the correct gear lube and friction modifier . I will have to wait until I find a Trac Lok rebuild video or find a better replacement LS diff
They are not difficult at all to replace. It's different then qhat your seeing in this video and very very easy to replace. Just comment the year make and model of your cj5 ND I can point you in the right direction. There is hundreds of videos on that trac lock. It's almost the same in Mt 95 dosge 9.25 rear-end
Hi there Paul, I got through my Dana 44 finally. What a tedious task! Ugh...so now I am going through my dana 30. New carrier bearings and pinion bearing. I have the pinion depth of 2.250 starting point. The pinion head has 2 surfaces to measure inner circle machined, and the outer circle that is machined deeper than the center. Which do I use for the depth? I checked the pattern and it was terrible. That's whats up...ugh... 1998 Jeep Grand Cherokee, front axle. Ok. After watching the Dana 44 pinion setup, you depth checked to the center of the pinion. Should be good to go, but I would love to get a reply back on this. Thank You again!
Thank you for a very informative video. I have used it as guide for my recent replacement of the clutch plates in my Jaguar XKE 1965 diff. which I'm currently also are swapping from 3.54 to a 3.07 gearing. After assembly the carrier with new clutch plates I noticed that the axles for the spider gears seems to be loose in the carrier housing. I am not sure if they were loose before changing the clutch plates. I have put the carrier into the diff housing and startet setting up and shimming the new ring a pinion. When I turn the gears i can hear a rattling from the loose spider gear axles. Is it normal that the spider gear axles are a little loose and rattle when turning the gears by hand?
@@GearBoxVideo Thank you for your reply. The gear wheels are actually not loose. It only the gearshafts which are loose. Correct me if I am wrong, but theoretically the shafts/axles can be loose if there is even pressure from both sides of the clutch pack. They are not fixed in the housing and only "sit" in the triangular milling. Or have I totally misunderstood the matter? For your information I have used a Spicer/Dana 44 clutch pack. Perhaps this is not working with the Jaguar/Thornton power lock even if the plates fits fine in the housing?
Is it safe to assume, that this carrier will fit into a solid axle DANA 44, like out of a Jeep?... is the strength less or more, carrier to carrier?... Again, thank you for the great content, as always.
Carriers have different bearing arrangements. So the Jag 44 has different carrier bearings than a Jeep. However you can swap ring and Pinions if you know what you are doing. Jags have bigger ring gear bolts and unique pinion splines. Carriers cannot be swapped.
Hello again, I messaged you once before I love the videos, I spend about a week with your stuff just playing in the background of the shop just to enjoy learning, Im rebuilding a dana 60 true-lock, for my truck, I disasembled it and it didnt seem like the "clutches" have any cluth material on them, they just look like metal, is this right?
Good morning, What type of oil, what viscosity index should be put in this model of limited slip differential ? 80W90 LSD or 75W140 LSD or.... ? Thanks
@GearBoxVideo Hello, I am a Frenchman who is restoring a 1957 JEEP CJ-5. I have a DANA 44 bridge in the rear. I seem to have a Power Lock type limited slip from Lock Right. I did not disassemble the differential (Just opened the rear axle housing). I have pictures. Where and how can I send them to you to tell me if I have a Power Lock limited slip? Thank you for your valuable help and kindness. Sincerely Google translation
Hi there, I have a hydra-lok/ vari-lok on my Dana 44 aluminum/Dana 44 HD. I was informed I cannot service it. But the clutch’s maybe can be changed and fixed. Can you help with some info/ your opinion.regards
Hi, could you help me please?, Im in the UK & I need a cluth pack for a XJS Dana Power lock diff, here they are craxy money, what other vechicles use the same clutch pack? thanks
This guy is one of the world's most knowledgeable on this subject, he shares his incredibly extensive knowledge and skills with the world for free, and you want to come along and tell him how it's done?? Very brave ;) But while i'm here, it's "you're", as in "you are", and "loctite" is a brand name... He is correct, the factory never used loctite, hence, the lock plates... Those bolts aint goin anywhere.
My powerlock had a 30yr old dark coloured thread locker so I wonder if I should disturb the ring gear bolts, which I notice you re-use. Mine also do not have lock tabs which are difficult to obtain. Would you leave as is? Your videos are the best out there.
A real mechanic has educated fingers and hands - which makes you a grand master :-) and a joy to watch. Be well in these troubled times.
Let me just say WOW. What a find on RUclips! You are a first-class builder. Someone who takes pride in their work! Getting ready to build a ford top loader. Subbed.
Thanks for another great video, Paul. I see no reason that I can't rebuild the Dana 44 Powerlock in my '88 Corvette.
Thanks for show us another very detailed video.
Great video Paul thanks for sharing your knowledge!
Glad it was helpful!
Thank You Paul. I always learn something when i watch you do your thing. Take care
Glad to hear it
I did two tabs once... didn’t make it home that night😆 Great content always learn something, keep em coming.🛠
You sir, are a true professional! Thank you for sharing your knowledge and experience with us. Stay safe and healthy.
I’ve had a number of 500 hp plus cars with GM 8.5 LSD’s...they all worked flawlessly and never wore or broke
Thank you very much for this leason!! Helped me a lot to understand how those “auto lock” diff works
Just got a new subscriber and a new fan haha
Nice job Paul.
Very nice.

No. I've only seem manual fork lift units
Try contacting aittransmission.com and velvetdrive.com
Real good one. Thanks!!!
Nice video, thanks
Why didn't you soak the new clutches in the oil?? That's recommended for every brand new clutch pack
I found it makes no difference. I do lube them and I do not get any clunking or chattering issues. Sometimes using the wrong oil creates more chattering issues.
great video
Easy....for you !
Cool vid
Thanks 👍
Once again, you take that which might be scary and make it simple...
Thanks

Very nice, Paul; thank you. Are the Dana 44 ring gear bolts normally right-hand thread?
Yes they are

The gearset should be tight. If you can move the axles independently then limited slip obviously is set too loose
@@GearBoxVideo Thank you for your reply. The gear wheels are actually not loose. It only the gearshafts which are loose.

There are diffrent size bevel plates. The axles float since it is the bearing assembly that supports them

yes they are just metal
Brilliant video. The right hand bolts of my carrier had thread sealer on, so presumably torqued up dry but you lubricated yours.
Great video! Do all of the power-lock differentials have 4 spiders?
Yes
Nice!! Stay safe...:-)
Always!
Good morning,
What type of oil, what viscosity index should be put in this model of limited slip differential ? 80W90 LSD or 75W140 LSD or.... ? Thanks
I use 75-90
Great. 👍👍👍
Paul . On the clutch plates could you use the Bead blaster fine grit to remove the Glaze 🐤😨
You just want to break the glaze. Depending on the pressure you can ruin the surface.

Hello, I am a Frenchman who is restoring a 1957 JEEP CJ-5. I have a DANA 44 bridge in the rear. I seem to have a Power Lock type limited slip from Lock Right.
I did not disassemble the differential (Just opened the rear axle housing). I have pictures.
Where and how can I send them to you to tell me if I have a Power Lock limited slip? Thank you for your valuable help and kindness.

Thanks.
A lot different than a Dana 44 in a C4 Corvette, I have a Dane 36 the housing itself is worn out, even with new clutches there is to much slip.
Get a stick rear. They seem to be available cheap
Can you tell me where you got the new clutch package from? But I want the more aggressive one because it is in my old hot rod
you would be more agressive by changing out the bevel discs. There are different packs. I got mine from motive gear
@@GearBoxVideo right on I'll look into it
💖💖👏🏼👏🏼
Do you have to break them in when you replace the clutch pack? I replaced mine and it really chatters ….only drove it a couple miles.
Make sure you use limited slip additive with the oil
Hi there, I have a hydra-lok/ vari-lok on my Dana 44 aluminum/Dana 44 HD. I was informed I cannot service it. But the clutch’s maybe can be changed and fixed. Can you help with some info/ your opinion.regards
I haven't seen any parts for those and don't have any around so see what's in them. What vehicle do you have?
@@GearBoxVideo Hi thanks for the reply. I will send you e-mail with detail. regards
Hi, could you help me please?, Im in the UK & I need a cluth pack for a XJS Dana Power lock diff, here they are craxy money, what other vechicles use the same clutch pack? thanks
Spicer part number is 22233X. They are available on my website www.5speeds.com. Maybe you can search the Part # in the UK
Your supposed to locktite the ring gear bolts unless they are reverse threads
That's what lock plates are for. The factory never used thread locker.
@@GearBoxVideo Everyone has something to say I say he did a damn nice job THANKS PAUL.

Hi are you able to change the gear ratio on these by just changing the gears.
Yes but some need spacers for the ring gear bolts
Hi
oops its a dana 60 powerlock im rebuilding, I
All the same... could have different bevel plate orientation
My powerlock had a 30yr old dark coloured thread locker so I wonder if I should disturb the ring gear bolts, which I notice you re-use. Mine also do not have lock tabs which are difficult to obtain. Would you leave as is? Your videos are the best out there.

You are welcome!
