    Last night outta the blue it started to make loud noises. Sounds like bolts in a cement mixer. Temp got up to 240ish. Pulled over immediately and let it cool down. Same thing bone cold today. I thinking bad bearings.

    Noise+heat=$ At this point, opening it up would be step one. I out can try to wiggle the drive shaft to see if it is the pinion gear bearing, or jack up that axle and turn the wheels to hear/ feel something there, but it's all going to be something ugly inside. Drain the grease out and indentify the pieces of schrapnel that come out.

  4. Don't drive any further.

    do like A5 said. cut open a clean dry gallon water jug. pull that plug and see the gold mine dump out.

    Start looking for another 13sp now.

    Look at your air bags to see if they are all the way up, that can make sounds like the end of all?

    This!!!! First thing to check. Sounds real bad if you leveling valve goes bad!

    Odds are you got other issues though.
