I have decided to post here after reading some great "how to's" and needed a bit of guidance. This forum seems to be the most straight forward of the many I have surfed.
The Facts: I purchased a 2000 4WD Blazer LT last Saturday. The people who had it always paid to have it worked on and had a bad run of problems and a few bonehead mechanics I learned. They had tired of dumping money into it. It had classic fuel pump symptoms and I told them so. They said they had the pump replaced a month earlier and weren't going to spend another dime on the Blazer and bought a new car. I bought it cheap and trailered it to my house.
Got it home and hooked up the fuel pressure gauge, 60 PSI when pump kicked on but fell to 10 when it cycled off. Bad check valve in the new pump. Replaced the pump again and I was on my way.
Drove like a nightmare though, all over the road with bad bump steer. 142K miles with original ball joints. So a full set of Moog joints, idler arm and alignment cured 90% of my problems. The last 10% is tough to determine though and hard to describe.
When I hit a bump at highway speeds now I get a movemnet that is best described as a fish swimming. The truck tracks straight down the road and steering wheel remains true, it just "wobbles" sort of. My research had led me to belive control arm bushings may be the culprit. The shocks dampen the bounce fine and the movement is more side to side than up and down. That is pushing me in the bushing direction. Oh and I put a new set of Yokahama tires on it and all are properly inflated.
Any thoughts or input?????
