I recently did a lot of work on my 91 D250. New springs, shocks, upper and lower control arms, ball joints, wheel bearings, and center link. After all this I took it and had the front end aligned. The problem is now my steering is VERY sensitive. It doesnt pull at all but the slightest turn of the wheel and your danm near in the ditch! It just feels squirrley. I took it back for a second alignment but they could find nothing wrong. Anybody have any ideas on why my steering is so sensitive and how I could fix it??????
Thanks

 

What make tires you running and are the fronts same brand and type as the rear tires?

 

I forget the make off the top of my head but they are the same front and back. I even tried rotating them but it didnt help.

 

Just because an alignment is "in specs", doesn't mean it is necessarily right for each vehicle. Just the addition of a passenger or load in the bed will change the alignment slightly. If your alignment shop is reputable, they should work with you until your satisfied. Are you using a local tire shop or repair center for the alignment work? I would recommend finding an actual "frame" shop that specializes in bent frames and alignments. These type of shops know their stuff and aren't just a bunch of kids fresh out of trade school. It sounds to me like you need to crank some more toe-in into it. The other thing would be adding some more positive caster into it, but I bet its the toe in. You might want to just give each sides adjustment sleeves a half turn to shorten the distance between the inner and outer tie rod ends and go for a test drive. You can always turn them back.

 

Post up a picture of the alignment sheet they gave you.

 

Did anyone adjust your steering gear box? If yes then possibly got adjustment way to tight on sector gear.

 

This is a local shop that I am not all that impressed with. I may try to find another shop. The reason they gave me for the squirrley steering was that when I changed the springs that made the truck sit a little higher and threw off the steering geometry.
No alignment sheet sorry.
No I have never adjusted my steering box and as far as I know no one else has either.

 

So the steering geometry was off when it came out of the factory with new springs under the front? I call BS on that one. Did they put a bunch of air in your tires? Every time I go to a tire shop they pump my rears up to 75-80 PSI and I CANNOT drive it like that.
