never followed up on this stuff I guess....
Since the driver side was in great shape, I didn't change any parts on that side. Adjusted both and the ebrake works great!
Lowered all tires to 75psi, it rides much nicer than at 105. That should be approx. right for the front axle and is probably still WAY more than I need for the rear. I'll have to keep an eye on tire bulge when I get a heavy trailer on there again to make sure sidewalls aren't contacting. They're relatively close but with the combined weight rating still around 12,000# at 75psi I don't expect much bulge.
Finally caught a replacement airbag cheap so I have a pair of them coming. Apparently on the slow boat from china with a mid-June est. arrival.
Found a cheap set of vent visors on fleabay too. "free money" spent on both of these things with Discover rewards and some un-transferred truck parts money in the paypal acct.
