ep82 Starlet GT (C52 non LSD box) drive shafts

[Frankieflowers]

Hi guys.
I bought a C52 gearbox pulled out from a Starlet GT ep82 and I put ot on a ep91 Glanza V engine in my Corolla Ee111L (European version).
When I put the Corolla 4efe drive shafts in I found out that the tripods were cracking which means that they are too long in this gearbox.
When I bought the gearbox I was insured that it would’ve been compatible with the Corolla C150 drive shafts but they are not.
I did some research and zi found out that the internal cv joints are the same on both Starlet and Corolla. The external cv joints are different. The difference in length is in the arms so I need ep82 GT non ABS non LSD drive shafts to be pulled apart and mixed with the Corolla external cv joints.
Anyone has an opinion and eventually tips to find these drive shafts? Thanks!
@Jay

Nobody has read this yet so I can update the post.

we figured out that the ep82 GT drive shafts are actually 63 cm compared to the 61 cm of the Corolla 4efe C150 gearbox. This means that the noise that comes from the tripods isn’t caused by the driveshaft length. At the end of the day when the car was on the bridge I spun a wheel and I noticed that the other wheel wasn’t spinning backwards but in the same direction instead. After checking that the gearbox was in neutral we double checked and the wheels were spinning together and you couldn’t block one of them. How could I possibly receive a working your box with a failed diff?
The other question now is if I would rather get a diff LSD and replace it instead of getting a C 52 box from an ep91?
Gear number 3 and 4 ar shorter on the Glanza turbo compared to the GT. The Corolla is a heavier car compared to the Starlet. What do you guys think?

Hi Frankie,

Both wheels turning the same direction might indicate the presence of an aftermarket LSD.

Can you take the shafts out and look into the diff? If it's a stock diff you will see a metal bar in there, an upgrade will have nothing.

or a completely solid piece (looking like a coin) in the centre (helical style LSD)

We checked and it has a metal bar. So weird the orbital is blocked.

Instead of returning the gearbox and getting a C56, I decided to keep the C52 and buy a Quaife ATB diff. I noticed that the C52 has higher value on the market and it is worth it to keep it and upgrade the diff to a LSD.
What do you think about it?

 

[Jay]

I would tend to agree with that.

Also interested in the current diff behaviour - when you manually turn each side, the opposite wheel turns the same way both in neutral and in gear? Is it the same for both left and right wheels?

Yes when I turn the left or right wheel then the other side moves the same as they were on the same shaft. I think that the orbitals are damaged. I will take pictures and shoot a video when I will disassemble it. I had to buy all the tools and hopefully I had the manual already. Only problem it is in German

We finally managed to Open the gearbox and first first glance it looked perfect but then we looked at the magnet and we found this

After panicking I looked around and I couldn’t find any missing bolt. I obviously was hoping the boat didn’t come from the forks. Then my partner showed me the two bolts that were in the reverse gear plate and we immediately had and idea of what happened.

There were two different kind of 12 socket bolts that shouldn’t go together in the same position. So probably be dropped one in the gearbox and didn’t bother getting it out. They just replaced it with a different bolt. The problem is that the boat went for a journey and end up on the magnet. Apparently there are no damages besides some small metal parts on the magnet. That is quite normal after several miles. In fact the gear shifting was nice.

regarding the differential, we immediately noticed that it wasn’t the genuine part but it was actually a LSD. And nonworking LSD. And unfortunate situation for me that could’ve been very positive is it worked. The differential bolts were loose. What a mess!
Tomorrow we will get the new differential LSD in and hopefully we will fix the problem and I will enjoy my new gearbox after having to Customize the transaxle corolla’s bracket.


there are small cracks in the gearbox that for suspicious and I would like to know from you guys if I should bring it to be welded before I close it.

 

[Frankieflowers]

I cannot find out which brand is this one that I see in the guide you sent me in the link. Can you help me find out?

What a mess Mate hope you can sort it out

 

[Jay]

Yeah, sounds like you have inherited someone else's mess there. Unfortunate situation but at least you have a plan in place to move forwards.

Can't really see for certain in the pics but the bolt doesn't seem too banged up. As you have said it's probably dropped during reassembly and the magnet did its job.

When you say the diff bolts were loose check the ring gear teeth for damage before you put it on the new differential.

Looks like the TRD I have here:



Meant to be a good option (not too aggressive) and worth a few coins. Might be worth making sure it's not dead before binning it!

It's been a while since I've opened a box but those cracks look a bit worse than any I remember seeing? Could be nothing to worry about or could be a headache waiting to happen, not sure without looking at a few bell housings to compare unfortunately. It's possible the muppets putting the box back together caused them as well?

We all agree I haven’t been lucky but instead of replacing it with a C56 I decided to open it and check what is wrong. The gear shifting is very good so with no leaks I thought it was a good idea to buy a new differential and swap it myself. Worst case scenario the guys from the shop will ship another box but I will lose the C56.
About the cracks I don’t think it is a threat because they are small and probably came out because of the material density. They are not going close to the structural point. I hope so I already spoke to the welding shop and they said that I should do the pressure test because the cracks are too many and only the dangerous ones should be welded. In my opinion I would skip this process because it doesn’t seem to be a threat as there The internal layer with cracks is very thin. I feel like if I would get those cracks welded I would see more in a few months.
About the differential that is another weird thing. There are scratches on two sides and it is blocked. While riding the car I could only turn without hearing noises bye stepping on the clutch pedal. That would free a little bit the wheels. Terrible feeling
I just spent €1000 for a new difference. I spent 500 pounds plus shipment and taxes for the box. I am no billionaire guys. The car is on the bridge with the box open and obviously the shipment company is taking a nap while I already paid import taxes and I will have to wait until Monday to see the package. Do you know how I’m feeling...

Thank you mate! I am way too deep into this cartooning that I will not stop until the apocalypse happens we must be close then!

Can you send me some information about the TRF differential I pulled out of the gearbox? I cannot find anything and I want to inspect it.
I don’t think that the Muppets could crack the whole plate by tying up the balls that were actually nice. I believe it is a matter of week material. I am curious to see what happened in my C150 gearbox. I bought the tools to get it apart and eventually repair it. I would’ve kept that one if it could fit a LSD differential. The gear rates are the same as the C52.

TRD offered two types of limited slip differential, the mechanical clutch type (which we both look to have) and a helical version which is more street friendly. The mechanical type is the only one that spins both wheels when one loses grip completely so it's the one to have IMO. They come set as 1.5way (works on acceleration) but can be changed to 2way (works both on and off the throttle). I'd advise the 1.5way as you will have more confidence on the brakes.

I've some TRD catalogues here. It also features as a dealer-fit option in the Glanza brochures which I appreciate!

Would agree on the C150, get her cracked open. You could end up with a spare LSD gearbox all being well.

Thank you for the information. If I can get some details to open and check what went wrong with the differential I might be able to repair it. The first plate you can see through the holes is blue. It means that The temperature was very high and something happened.
Let me know if you can send me a PDF with the procedure to open the differential and also how to close it after installing the bearing in the correct position. Thank you!
