Torsen Lsd - Need Advice

[Max_HR]

Finally got my self a torsen A02B diff from IS200 sport model (year 2001, 150 000 km) :)

For now, I just brushed it up and cleaned surface rust. There is no signs of leakage and it turns very smoothly. My plan is to change the oil and put it on. Question: should I change the oil seals now or just leave it like this since there is no leakage present? I don't want to touch it if it's not necessary. How long it usually takes for diff to start leaking? Thanks!

Just change the oil mate I've never heard of a diff leak .dont mess with what already works .

You're right. I'll put fresh oil and drive it. I mean, slide it Any leak can be fixed later on.

I can't see it leaking mate , Castrol do good diff oils .

Diff replaced :)

Just, noticed that they left upper mount stopper. I'm not sure why because it gives extra rigidity and reduces diff movements I'll ask my mechanic tomorrow. Here are some pictures of upper mount stopper:

He forgot to put upper mount stopper plate. Now everything is fine :)
