I was browsing Summit and found these neat little drain plugs are are intended for automatic transmission pans. They are pretty cheap, and made me think that I have to drain the rear lube after the new R&P break in. Seeing as the differential cover will be off, thought about maybe adding a drain plug.
I know the plug will not be low enough to drain all the oil, and I won't be able to scrape the bottom of the housing clean. But I was also reading where the (numerically) higher the gear ratio, the hotter the gear lube runs. That is a general statement, and other factors affect the temp. But it makes sense to drain and refill every 40K miles or so, especially as it only takes 1.75 qts of lube.
So what do you think? Is it worth the trouble to add a drain plug one time or pull the cover each time and buy a new gasket?
It would also allow the use of a magnetic plug, so you can easily see if there is metal flakes building up.
