Rear Diff washer/gasket needed?

Do i need a washer/seal for when I replace my rear diff fluid. Like the rubber gasket that is replaced everytime that the oil is changed. I have the 3 quarts of mobile1 but I cannot find the answer to my previous question. I have read the tutorials and none say anything about a washer,so I guess no washer?

 

From what I've gathered, some elect to reuse the washer and some elect to change it with the oil. Since it's not done as frequent as a regular oil change, I can see where some say it is probably good to do. But if the old one still keeps it sealed, that's fine too. User preference I suspect. the washers are not much, but I guess it depends on how easy it is to get them where each person is.

I opened another window and checked this thread, it has part numbers on post 7 for the crush washers. Also mentions some reuse some get new. Depends on what you're comfortable with.

CLEAN ALL SURFACES AND RE-USE IT

PS. I think the number of times I've had that plug in and out exceeds the number I can count to on both hands, and I still haven't changed the crush washer.

 

Thank ya'll... I was going to reuse it, but since it is not changed as much, I will just go ahead and replace it.

 

i plain forgot to put the crush washer back on when i did this. No leaks for 5k miles lol. Think ill wait till its due to change it again to put it back on for obvious reasons.

 

Just remember to torque to spec.
