Hello guys!
I need your advice: I own Sienna 1998 (VIN WUO21575) and after front driver`s side CV Axle and Seal replacement transmission fluid is leaking from the place where Axle goes into Differential. What could be the reason of that problem?
Thanks!

It means he damaged the seal while installing the axle. Bring it back to them and tell them they need to repair at no charge.

Probably, I understand what could be a reason. When the first guy took off new axle from differential to replace the seal, he used a fork (like tie rods separator fork) and he damaged space on the axle where the seal installed. Here are the pictures:

You can see very thin like a ring (or nest) on axle where seal goes. Now that ring is bended - I marked it with red.
Could it be the reason of leaking?

That area you have mark is more of a dust shield, to keep dirt out of the seal area........The seal for the oil rides on the hub area in front of that marked area....
If a new seal was installed with the axle, I would guess he damaged the seal installing it.....That shield should to be straightened or removed though before installing a new seal.....

Can you see on picture that Seal has two parts - with small diameter and larger diameter. The part with a small diameter should be completely inside that nest for dust, and that nest push the Seal into differential. But now I think it`s now completely inside and because nest is damaged it doesn`t push the seal to differential.
Is it really easy to damage that Seal, because the rubber is quite thick. And guy installed seal with a special tool for seals (beat with a hummer)

Yes, it's very easy do damage it when installing it of installing the axle. If the seal is leaking and if the case is not cracked,then the seal is damaged.

I understand, thanks! Does that damaged nest plays the role?
Could you give me any advices how to take off that axle, because it is very difficult to take it off.

Why are you trying to take it out? If someone else installed this axle, then it's their problem and if you mess with that, they can refuse to cover it.
That ring is just a sling shield and it prevent road debris from getting into the seal.

The guy who did it is not very experienced I suppose, he did it in his house. I went to transmission guy yesterday, he tried to take it off but he couldn`t and he was busy, I will have an appointment with him next week.
If the reason is in differential bearing, can I hear the noise or it`s very quite?

The reason the seal is leaking is it was more than likely damaged when your guy installed it.....Those type of seals can be tricky to install.....
The ring/nest is just a 2nd seal.......a seal for the seal.....all it does is protects the oil seal from junk getting at it......
The factory correct 100% way to fix this would be to install a new seal and new axle with a new nest......
If it was my car.....I would get a new seal & pop off the nest/ring/shield & run without it.........most axle don't have those anyway

Thank you for recommendation! I am going to buy new axle and seal.
Interesting detail: after the second guy tried to take the axle off, fluid didn`t leak for about one day, after 25 miles driving.
I am going to buy that axle, could you please tell me if it is Ok that it`s called "Import" axle?
