Probably your steering box. They get sloppy over time.
I actually tried this a few weeks ago, but I found that the tighter steering made it worse. I was under the impression that you wanted SOME slop on the larger trucks
. When I tightened it a quarter turn, the input seemed to sudden and actually made it harder to control the truck.
Is steering really what is causing my problem? I thought it would be something else with my suspension
or other front end components. I hit a large bump last night and man......the truck just went all over the road. Could it be because I didn't replace the rear shocks? Could my "new" front shocks be worn already?
Was it a Toe and Go Alignment or a Full one including Camber/Caster?
Full alignment. I can post the before/after when I get home
tire pressure can cause this too. If I air up past 55 unloaded i get some good wander over bumps
I'll double check the pressure, but I believe its set at 50 front/70 rear as stated in the door jam.
I have been down that road as well. Like you I replaced my tires and balljoints. This helped some. I then replaced the front shocks for Bilsteins. This help more. Due to availability issues, I had to wait a couple months for my rear bilsteins to arrive. During that time I too experienced the rear end skitter when hitting large bumps. As soon as I added the rear shocks, that ceased to be a problem.
My steering is still a touch loose but with 220k on a 99psd, it is as good as its going to get without a new stearing box. It is however a whole lot better than it used to be before I changed everything out.
I noticed your from Kansas... I though all your roads are straight out there. You shouldn't have to steer much anyhow!
LOL most of our roads are straight.....and actually when I'm going through a curve its no problem at all......its actually when I'm going in a straight line. The truck seems to wander from side to side and when I hit a bump.....man......look out!
I believe the movement is all coming from the front, but I could be wrong. Could my OEM rear shocks be the problem?
I've also heard that the MOOG ball joints I used could be the culprit as well as they are "too stiff". But I was under the impression that MOOG was top of the line when it came to steering components.
