Hoping somebody can help me out here....a friend of mine brought by an 87 Blazer, 350 tbi, 700, 135000 miles, 10bolts, and 31's. We took it out for a drive and the steering is extremely "vague" you must saw on the wheel alot more than what u should have to to get much of any response. Then we took mine out just for shits and giggles to make sure it wasn't my imagination or a case of err...K5 envy lol but my 89 was extremely tighter. We looked over the truck and it doesn't look like it has ever plowed and the frame appears in excellent condition as it has been under-oiled since new. The truck also has just went through inspection so all of the front-end pieces are tight. The only thing we can really come up with is that the steering box may be worn out. Any ideas as to what this ailment may be?
