Differential Leak.

Post by ivaldes1 » Sun Sep 22, 2019 10:12 pm

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.

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

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. :)

At least you got two years out of it before it leaked Ignacio! :)
Mine leaked right away. :oops: 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.
