When you say "super rusty", did you try to loosen them and they are stripped out or are they just 'rusty'?awdVibeNoobie wrote: ↑Fri Jul 26, 2019 7:55 amWhen I was looking a bit closer over my Vibe, I noticed that both the rear diff drain and fill plugs were super rusty.
That's what I was guessing.
I haven't tried to loosen them yet. I want to change out the fluid and usually with my luck I strip out rusty nuts, bolts, screws, etc. I rather be safe then sorry and have new replacement drain plugs on hand.ehoff121 wrote: ↑Sat Jul 27, 2019 7:50 amWhen you say "super rusty", did you try to loosen them and they are stripped out or are they just 'rusty'?awdVibeNoobie wrote: ↑Fri Jul 26, 2019 7:55 amWhen I was looking a bit closer over my Vibe, I noticed that both the rear diff drain and fill plugs were super rusty.
The drain plug has a magnet in it to catch metal bits, but the fill plug does not.
Even stainless steel will rust when exposed to road salt brine...
I have a hazy memory of a front transfer case that had a bolt for the fill- could have been on my wife's Highlander...
Generally copper or steel. I don't know that I've seen an aluminum washer on these things. If it's like the transmission/oil pan, it's a crush washer.awdVibeNoobie wrote: ↑Wed Jul 31, 2019 12:44 pm What material is the gasket for these plugs? Copper? Aluminum? Other?
