grit felt almost like very small sand, but seemed to sparkle a bit in sun. Had axle out to replace stripped stud and wiped from grooves at gear at end. That gear thing looked ok, but of course my non mechainical knowledge is legendary ........ axle now at shop for stud replacement .... any way to manually flush differential other than just filling, driving, doing it again ?
Oh Andrew, you know I know little about cars .... can I flush that differential out some how? I do have a fine man from Aptos, Ca.who moved here that helps me when I can get him to feel sorry enough for me .... and here's a few better shots of Sal ....
The "flush" question just came up on in the tech column of the BMW club newsletter, Roundel, and the answer was a resounding No, though I forget what component it related to. I wouldn't put in anything but 80/90 or whatever similar heavy oil you're using. If you take it all apart, sure, clean it up with a good solvent. But I wouldn't pour that through myself.
Thanks Andrew, car sat for 20 years, first time I changed that fluid, my goodness, smelled like someone shat in there, will probably just make a couple rather quick changes and see if that helps clean things up some.
