front differential problems

G80, GU6, GT4, GT5, WTF? This section is for gearing and driveline stuff.

from the front differential ran the oil. I decided to change the sealant. but I found a completely different sealant in previous masters work :(. In the picture you can see what should be the sealant in the center of pic. And on the right of pic was the sealant that was inserted. maybe you know the strength o has to be tightened bearing in photo on the left. because when I took out the sealant the bearing fell out. but it may be that we will need to change all the bearings and dentures, since I ran with a non-curved bearing. and now there is a sound from the gear unit when I turn on 4wd.

I don't think there's a torque spec for the bearing adjuster. It's technically supposed to be set during gear adjustment. If it is making noise, I'd probably suggest pulling the diff and going through the setting procedure. Start at step 4: viewtopic.php?f=72&t=5441

However, we can probably assume the opposite side seal is still stock and the adjuster hasn't rotated. If you tighten the driver side adjuster all the way down and then turn it one more notch, it may be acceptable.
