Hi, My 12 rivet differential leaks slowly at the two lower most bolts. A few drops a week. See picture. The fluid level was down as expected when I opened the filler bolt so it isn't communicating with the engine oil. The fill hole does not appear to be leaking. How much torque should the bolts be? I did find the bolts loose a month ago and tightened them but it is still leaking. Is there a no-drama way of fixing this? I took the whole thing apart to replace the thrust washers. I would rather not have to take the whole thing apart again to fix this. It hasn't leaked until about 6 months ago.

Re: Differential Leak.
This differential did not leak for about 2 years so is it normal for them to start leaking? -- IV

Re: Differential Leak.
For a few drops a week, I would slide a butter tub under it to catch the drips and top off the level a couple of times a year.

Re: Differential Leak.
At least you got two years out of it before it leaked Ignacio!
Mine leaked right away. Smooth, clean surfaces with the dings and high spots brought down with a file...
I need to do this yet: Perhaps clean the bottom mating surfaces with thinner, dry it and smear on some ultra black.
Good reminder tho! I need to check the fluid level before driving it/after sealing it. Whichever comes first.
Snug.
