Subaru DCCD Differential Rebuild

- We are rebuilding the DCCD center differential in Nic's STI swapped Subaru Impreza! Mooresport out of Quebec Canada makes the replacement clutch pack that we used in this video. Rebuilding the center diff saved a lot of money compared to replacing the whole unit.

Sweet video! One correction/clarifying comment: At 8:55, you say "...these planetary gears are just for centering the whole clutch assembly..." Actually, the planetary gears are what determine the basic torque split between the front and rear axles. With the DCCD clutches open/no current to the coil, the center diff is open, and the planetary gears are designed to split torque approximately 60/40, with a rear bias (exact split can vary slightly depending on model year). Just wanted to throw that out there!
I love seen these type of videos when you can fix the problems by reconditioned the parts inside and save a load of cash good work boys
Only video I've been able to find on rebuilding one of these! Will definitely come in handy for when I convert my Bugeye to 6 speed and rebuild the center diff
Good luck. Did an 04 6 speed swap on my Bugeye back in '15. First drive had a terrible sound so pulled the tail shaft housing off, replaced all the bearings and ended up swapping in a known working DCCD just in case. My budget swap turned way more expensive due to the parts I replaced. Those bearings are $$. Still have the other DCCD and may entertain rebuilding it now.
@@cordcd7 I plan on buying a whole STI drivetrain with a DCCD controller from JDM Chicago
I found a very similar setup in a transfer case in a Ford Explorer a while back. Interesting design. Always nice when you fix something and it clears up issues you didn't even know were related!
Thanks man, this video helped me diagnose my center diff after an improper tow!
fantastic video and very well explained of the inner workings of the DCCD.
Man you guys dipped out for a while glad to see new content.
Had some life things happen, then I broke my wrist in a car accident. Getting back at it 👍 -donovan
Camera dude needs some help with shot focusing. Good content, but man
Question. I know this is an old video. Concerning the center dccd if bad. I checked my MAPdccd settings and everything looks good but I am now experiencing some weird lunging feeling when doing power pulls. Almost like the front and rear wheels are fighting. I'm thinking my center DCCD is shot. She's 800hp and only started the past month or so.
Your camera guy is giving me vertigo and I have now thrown up my entire lunch into my lap.
What probably happens if the center diff is clicking and bad, but it's still driven? Does it stop putting power to the rear wheels eventually? Or the front wheels?
I love how knowledgeable you are on first gen Imprezas. It’s been my dream for a while to get one once I pay back my student loans. Keep up the good work, and looking forward to more videos soon :D
Thank you for this Information about the DCCD ✌
Thank you for the breakdown (No pun intended) of the DCCD!! I look forward to the time my STI will Need this upgrade, for now I have an understanding of the components in their. ?? Question... I have always (since I bought the car with the very low 95,000 miles on it for a 2005) had a Very tight shift, meaning going in an out of any gear, any time, it takes a little effort... Any thoughts on her issue?? It is very stock and probably not raced in her life. Cheers mate ✌🏼
Great video!
Good video. Which model box is this dccd from? TY752 or Ty754? Cheers
great fuckin video bois
hey what transmission are you using? I'm having a similar problem with my 96 ra but I'm not sure if that shim kit you purchased would work for my 96, and I cant seem to find info on weather the center diff changes from 96 gen up to the 2002 gen and newer .the kit they sell says its for 2002-2005
Quick question. When you returned the center diff was it to the exact position or it just goes in?
does the dyno have the roller lock together with a drive chain or something so power can be applied to both rollers? just wondering because that would blow up the new center diff too.
It’s a Subaru specialty shop. The dyno didn’t blow the diff. Years of abuse on the drivetrain from the owner of the donor car wore it out.
My 2009 sti has a binding issue at slow speed when turning, if you walk the car with clutch only while turning you can feel the car slowly come to a halt. Makes a very unpleasant noise as well. I've narrowed it down to the center diff, but unsure if it could be something else within the drivetrain. Any suggestions?
fatal3sgte I’m having a similar issue in both forward and reverse, is yours making a clunking? And have you figured it out yet?
ceddyb11 think it’s the center diff, my 2010 Outback 6MT has the same issue, dealer quoted a whopping $3100 for the job. It’s a almost 8-10 hr job
@@ceddyb11 Sorry I didn't even get a reply notification, yes clunking sounds and binding as well. ruclips.net/video/wGpFxCntLPc/видео.html
Sounds identical to this video but I'll get a video of mine and upload it within the next few days. Finding info on the forums is a nightmare because it becomes a WRX dick measuring contest and trails off from STI topic.
@@RingZero Plus the centre diffs are worth big $ as a spare part.
@@fatal3sgte This was pretty much the same sound I heard after I swapped an '04 6 speed into my '02. I ended up swapping in another DCCD along with replacing the bearings in the tail shaft housing. ~$1000 later and the issue was resolved. Not sure if it was the DCCD or bearings in the end. Still have the original DCCD so I think I'll take it apart and inspect the clutch plates.
Hey! Did your DCCD make a noise being worn? What did it sound like? Possibly dealing with a failing DCCD.
No noise, it just slipped like a bad clutch almost
@@TIRESIDE did it slip like a bad cluth also with the dccd in free mode (green light)?
hey man where you order the the parts?
How much power does it make "Hp wise"
Great video, I am about to rebuild a viscous coupling for a 2011, 2.5i awd turbo 6 speed manual gt wagon, BR9, can you give me better info on the oil used pleased.? Subaru are appalling here in Australia, for parts & info, it is a secret society, parts rip off.

Des contact Corgiworx in Sydney they rebuild the centre diffs. Your centre diff is completely different to this centre. Its a silicone fluid that Toyota supply, Subaru dealers can not supply this as a spare part / fluid.
Thanks for the vid, but please work on your camera work.
What DCCD Controller did you put in the car? We sell them if you need one ;)
We have a DCCDpro controller integrated into our harness by none other than iWire 😁
@@TIRESIDE YAYAYAY!!!!!!!! :)
Did you get some Problems again, or did it still work since the repair?
✌
Still works!
@@TIRESIDE Nice. I think i try to fix the DCCD. Thank you ✌
@@TIRESIDE and what tranny oil have they been using/are they using??
sadly seems there are no rebuild kits for GR DCCDs. only rebuild kits for GD. the diffs are not the same.
It might be worth giving mooresport a call and asking about it.
Do you know rallispec has rebuild kits for the DCCD also?
Maybr they have for GR (not sure)
www.rallispec.com/dif_ohk_dccd.html 2006-2014 STi DCCD kit from Rallispec.
@@Romassj2 They do indeed, in fact their only DCCD kit is for 2006-2014 and 2015+.
what kind of gear oil do you use
Amsoil
Hey, Bro. my STI 07 makes this noise when turning: ruclips.net/video/bXXVEkISBx8/видео.html
Could this be a problem with the dccd or is it the rear diff?
It’s hard to tell from the video, could be torque binding from the center differential.
@@TIRESIDE Maybe you have an idea - I lifted STI yesterday with a floor plate lifter - and made the movement in first gear and in reverse, while completely turning the steering wheel - there was no noise. The hum sound only appears when the car has a load on the ground. Another interesting feature is that there is a hum sound even in neutral gear.
