buschiniowa Posted February 10, 2012 Share Posted February 10, 2012 99 legacy SUS. 2.5 16valve auto transmission. (ID# TZ1A2ZJEDA) When I replaced the front drivers side CV shaft, i noticed that the male splined shaft (which connects to CV shaft and is secured with a roll pin) coming out of the front differential was sticking out too far. I could spin the shaft freely, which I shouldn't have been able to do. The shaft wouldn't come out of the differential completely tho. It had just moved out of the transfer case by about an inch. So, I called a shop that was recommended by the local Subaru dealer, and they said that there is a clip inside the diff that must have come off and that it was "terminal". Said it would require so much $ to repair that I should just get a remanufactured unit ($2,000, no thank you). After that news, I came home and fiddled with it some more. I did get the shaft to slide back into the differential to the proper depth. I expected that it wouldn't stay in place, but now when I try to pull it out, it doesn't budge, which I would think is a good thing. So, what's the truth regarding just the differential component of the transmission? Is there a C clip or a split ring clip that holds this shaft in place? How is it that it is now apparently back to where it belongs and staying there? Does anyone have an mechanical drawings of the inner workings of this differential / trans? I don't trust what any shops tell me because most are just trying to sell something. Yes, I trust all of you anonymous strangers on ultimatesubaru.org more than most repair shops! Let me know what you think. Link to comment Share on other sites More sharing options...

Fairtax4me Posted February 10, 2012 Share Posted February 10, 2012 On the auto transmissions, the output stubs can be removed and replaced easily. There is just a C clip that holds it in place. When did you notice this problem? Before or after removing the axle? Did you try to drive with it like that? If the stub comes out of the side gear of the differential while driving it can shred the splines and damage the differential. Link to comment Share on other sites More sharing options...
johnceggleston Posted February 10, 2012 Share Posted February 10, 2012 some times, i hear, when the stub shaft comes out the cir-clip pops off and drops to the bottom of the diff case. usually this is not a problem. i heeded you can just remove the axle stub and pop on another clip and reinstall. no worries. but you probably do want to check it every now and then, in case something (else?) is causing it to pop out.

buschiniowa Posted February 10, 2012 Author Share Posted February 10, 2012 Naru - thanks for the mechanicals...that's exactly what I've been needing. Fairtax4me - I noticed this after replacing the CV half shaft on the drivers side. When i aligned the shaft flange on the output shaft, the seal was at least an inch from seating properly. I haven't driven it since. I've been working on many different issues on the car but am now ready to tackle this (hopefully) last problem. So, if I'm understanding you guys correctly, this shaft will come completely out of the differential and it's possible to re-install it without disassembling the entire unit? Now that I have the output shaft back in place and it appears to be held in place (I've tried pulling it back out and it won't budge), can I assume that it is seated properly and give it a go? I would think so but your opinion would be helpful. Thanks in advance. John Link to comment Share on other sites More sharing options...
Fairtax4me Posted February 10, 2012 Share Posted February 10, 2012 Since it was pulled out, you might remove it entirely and check the end and the side gear for signs of broken/stripped splines. Other than the possiblility of the seal being damaged, if the stub isn't chewed up. i'd put a new C clip on it and pop it back in. Link to comment Share on other sites More sharing options...
idosubaru Posted February 10, 2012 Share Posted February 10, 2012 yeah it's pretty simple. it doesn't seem like it should be on some levels, but it does simply pop out and pop back in. sounds like it came out during some work and just needed popped back in. sounds all normal to me. i mean, they don't typically come out very easily so that's not normal but i have pulled them out before. there's a million of these all over the country maybe just have someone send you another one off a junk trans somewhere? post in the parts wanted forum? might be worth the piece of mind knowing that part is good since it's so easy to swap out. if the front diff is hosed or gets hosed then you do have issues and a trans swap is the most likely solution, rebuilding front diffs just isn't cost or labor effective. and used trans aren't that expensive and are robust (hence the low demand, high supply, and low prices).
