Two Questions - first the backstory: I live in Tucson and made a trip to Phoenix this past weekend and took the 320G. Temperatures were 115 -120 outside and my tires were running anywhere from 111 degrees to 122 degrees on the road - depending on which side the sun was on. And my air pressures were around 140 psi (125 is cold). No problem going to PHX, but coming home - two miles from our house, the temps and pressures were the same (air temp 115) = I had to make a panic stop, non of the tires locked up or skidded, but after a mile or two, one side of my trailer tires the temp rose to 132 - the air pressure didn't change - stayed at 141. There was no smoke, didn't feel like it handled any differently. When we pulled in front of our house to park - and my wife got out to help guide me, I pulled forward and we heard a very loud screeching noise coming from the 'hot' side of the trailer. (We don't know how long it had been making that noise - we couldn't hear it in the truck). I had to get out of the middle of the street and when I backed up - the screeching noise started, then went away. Maneuvering the truck into it's parking spot (which included forward and aft) the loud screech never came back. My thought is the magnetic part of the brakes stuck and backing it up - released it - but I'm not sure if that's correct. The temp never went above 132 degrees and the air pressure never went above 141. I'm going to be taking the wheel off and checking the brakes and bearings; my questions are: 1) What's the best way to jack up the tire? I've read the post about jacking under the U bolts - and I've also seen jacking up on the frame. It looks like jacking up on the frame I should hook up my truck (not sure if that's correct) - 2) Once I get the brake drum off - will I even be able to tell if something is obviously wrong - or should I just buy a whole new brake assembly to be on the safe side? Thanks in advance for any advice!
