I found the axle
plate on the front end of the axle near the wheel opposite of the curb side. Can't read it though, either while under there or in picture.
I used a scrubby to clean it off. Seems like the black paint
has flaked off and it is quite rusted over right where I need to see it. What I can read suggests that the middle of the second line start with "CAP" and should be followed by the numbers I am looking for. I ran this photo through various brightness and contrast levels in photoshop but still couldn't bring it out.
Is there any liquid that might minimize the rust to enable reading it?
Probably doesn't matter, since the clearance is even lower than I imagined in a practical sense. It was all I could do to get under it as it is quite low and the axle is old. Even if it is over 2000 lbs. capacity, it needs replacing. Maybe should do it sooner rather than later, especially if Dexter is leaving the scene.
