Question for Rock Lizard...
I like the nice thick cover for rock armor purposes, and I like the drain plug for situations like trailside fluid changes after a river crossing, etc. But how do you get the metallic sludge off the factory differential housing magnet through that little drain hole? Did you remove your housing magnet and add a magnetic drain plug?
Id hope that people aren't so lazy that they are only buying a drain cover so they don't have to scape silicone every 12k miles. Part of the regular service is visually inspecting your gears and cleaning the magnet. If you aren't going to clean the metal off the magnet, you may as well dump your old fluid back in after you drain it.
Page 3, Post 4, I said the same thing about a drain plug not getting all the garbage out, and it is not too hard to take the cover off, inspect, clean, spary out with a little brake cleaner, wipe it out, RTV, and put cover back on. But most people wanted a drain plug, so I went with the customers' suggestions. Just because you have a drain plug, doesn't mean you don't have to take the whole cover off and do a thorough cleanup/inspection. I personally will take the cover off each time, but I wheel a lot and pretty hard. I guess one could look at it as why have drain plugs on the oil pan, TCase, and tranny, when it would be better to take the pan off and clean out the sludge everytime and inspect the internals. Maybe with a drain plug, one would be more likely change the fluid more often like the engine which would keep the internals cleaner and less buildup would occur?
