My truck is a 1974 K10, with a Dana 60 front and 4:10 gears. /forums/images/graemlins/cool.gif When I have my small tires (LT 235's) installed, it steers from side to side fine, in a normal fashion, with good response. When I install my 38" TSL radials, the steering response suffers dramatically. If I want to make a 90 degree right hand turn, I have to go pretty slow, just to allow the steering enough time to react. I realize that with tires that size, sidewall flex, extra strain on the steering, and the fact that it ain't no slot car all come into play, but it seems abnormally unresponsive with the big tires on it. I'm guessing /forums/images/graemlins/confused.gifthe steering pump is worn (belts are tight) or is simply too small. Am I correct? What kind of upgrades can I do without going full hydro steering? Thanks for any help!
