im lookin at a 1970's chevy truck, its lifted 6inches on 36's, he claims the 4wd worked last year, now the 4wd wont lock in, I'm wondering how much it would roughly cost to fix, and or what could be the problem. its also 3 speed with granny low.

Answer:

Hi do you not have any Literature on your sprinklers? If not you should get them to be serious these things are not toys they could save your life hope I don`t sound abrasive but they really are important.
The brand name is only part of the issue, you need to compare the speed rating for the tires. You should not use a tire under rated for your car. (according to the manufacturer, that is, they are just speed ratings, dont take a tire above the speed its recomended for.) and you need to look at the mileage ratings. The Uniroyals may be a good deal, unless the mileage guarentee is only half that of the Michelins. All things asside if you have the same speed ratings, and the same lifespan, and warranties are the same, go with the cheaper tire.
I tried calling an old friend that was interested in vulcanology, but no luck. I do know that at least some prefer to wear nothing but a fire-retardant helicopter flight suit and sturdy boots for the mobility and being able to sense the heat before it gets them. I would think asbestos suits would be much more expensive and difficult or impossible to find now, with the health risk asbestos presents. A material called Zetex is a fiberglass weave that can withstand some extreme heat, and for lower heat resistance aramid fiber (Kevlar) and Rayon are used in some other protective clothing applications. I imagine vulcanologists have made similar changes. Not much of an answer, I know, but it might give you something to go on for searches to feed the over-achiever in you.
no they are heat activated
