Watch how you adjust preload
In the October 2005 Land Line Paul Abelson covered the possible cause of excessive hub heat very well. From my experience, the usual cause is excessive bearing preload. A lot of people tend to adjust too much preload.
A friend of mine pulled an overseas container whose hub got so hot it melted the plastic window on the hubcaps. A serviceman noted that the cause was grossly excessive preload. Even the adjusting nut was difficult to remove.
Unlike other parts of a truck, wheel bearings seem to be tolerant of a wide range of error from loose – if the seal doesn’t leak – to tight.

And the good news is – good news
Just read the letter “The best tuna sandwich I ever ate” in your November 2005 issue from Mike Dowdy of Hartselle, AL. I wanted to let you know that is the kind of news we should be reading about Hurricane Katrina. Just wanted to let you know that Mike is a great person to take the time to share this with us.
One-size doesn’t fit all
I started running two-man in 1957 in a 1956 Kenworthhalfcab on four on four off with a sleeper cab where the driver had to get out and fold the seat up for the other to get in the sleeper. It had no heater or air conditioning, until ICC outlawed them. I have logged over 5,000,000 miles with 1,000,000 safety awards.
For the last 15 years my partner and I have left every Monday at 24:00 hours and run until Sunday morning. We log 5,000 to 6,000 miles every week. We haul hazmat and the truck is only turned off for reload as the motor is needed. To unload, we run five to nine trips a week within a 100-mile- to 600-mile-radius of Denver.
I would like to put Annette Sandberg in a sleeper for 10 hours and in seat for 10 hours after six days – she may be smart enough to see why shoe companies make different sizes.
I think Land Line is the best magazine. After I am done reading it, I take it to work for other drivers to read.
