I live in East TN. I have only had the truck for about 8 months. I did a carfax, and I am the 3rd owner. 1st owner lived in Haysi, VA and 2nd owner lived in same area I do. And yes, they occasionally use salt on the roads when we get snow (which has been rare).

 

I have had an 88 Sierra and an 88 Cheyenne and neither one of them had anywhere near this amount of rust underneath!

I had, until a few months ago an '03 silverado Z71. The brake lines were ready to be replacedas well. Over the course of it's life I noticed as the frame coating dried and flaked off, rust was soon to follow. In fact it was getting pretty bad on the frame rails front suspension and rear cover. I live in SE Pa where they go crazy with salt and drive regularly up into the pocono mtns.

That's a lot of corrosion, but none of it looks like serious rust through on body panels yet. The truck has been through nine winters and time does take it's toll. If you mean to keep the truck for a long time, I would jack it up, remove the wheels and put it on jack stands. Try to get it high enough so that you can work sitting up and scrape as much of the lose stuff off with a paint scraper as you can. Then sand it with a course grade paper to remove the worst of it. Then Have the underside undercoated. Ziebart comes to mind, but there are others that will do a good job. You don't need to sand away all of the rust - just get the lose stuff. Undercoating will adhere very well to a clean, prepared surface and the truck will be good for another ten years.

      Even tougher is the 5.0 / 302. That's what this one has.    https://postimg.cc/Z9XRrCSg   https://postimg.cc/4n3F3yzY   Just realized I had the airbox removed in the engine pic, lol.

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.
