pinion cup clean out.

[CASABROKER]

ready to put drive shaft into pinion cup.  is it ok to blast the cup with brake cleaner to get it clean?  My concern is will I want to get the hole cleans in the pinion cup.

The holes go through to where the final drive fluid is.

I didn't feel bad about sticking the little red WD-40 tube in there to
give a little blast to make the holes clear, I might feel a little hinkey about
having break cleaner in there... ida know...

I got the cup clean, and blasted the holes as the last step I think...

Wouldn't use brake cleaner unless the cup is off the final drive.

Try a good old fastion pipe cleaner.

Even a tooth pick. All you want to do is make sure they aren't plugged.

compressed air works good
