New steering parts rebuild and it still wanders.

[72farmer]

I just done a disc brake conversion on my 67 c-10.I used the stock height spindles and steering linkage from a donor 72 GMC.I replaced all the worn parts on the steering linkage.The steering sector is tight with no wear.
After getting it all done I took it to my local front end alignment shop and get it aligned.The frontend guy is very experienced and gets a good name on old stuff.The truck is lowered about 4-5" done by cutting front stock springs.The rear springs and F&R shocks were bought as a kit.
I am disappointed on how the truck drives because it wanders like it did before I replaced all the worn steering parts.
Someone said if you lower a truck without using front drop spindles it causes steering geometry to be off causing driving problems.Do you think this is my problem?Or do I complain to my frontend guy?

do you have a sway bar up front??

[72farmer]

No sway bar.No steering stabilizer.

I have heard that with that much drop with springs only you will have geometry problems.

[michael bustamante]

Drop spindles and the correct drop springs will work wonders for you. Also, you should replace all the ball joints. What did you replace on the steer rack and did you add power steering?

I agree with the others, I don't think you can cut that much out of the front springs without running into problems. I think your alignment guy probably did the best he could with what he had to work with. The alignment itself is probably OK by the numbers but the overall geometry is whacky....

the sway bar will make a world of difference how the truck tracks// but I too agree that drop spindles are the way to lower for best tracking and run out

could be your box also , but , a front sway bar is a must for cornering ,and curves

check the rear suspension also.

I was initially going to cut my front springs by one full coil, but when I lowered the jack, it was obvious that the suspension components were drastically close together, meaning they almost bound up when you made any turns. I'd bet this is your situation. I bought a set of 2.5 inch lowering coils up front, and 3 inch drop spindles for my build and everything is where it should be, no where close to hitting any of the components. One question for you....look at how your tie rods are attached to the center link (drag link),are they behind the center link, or are they in front of it.....it does matter.I'm not questioning your abilities here, just wanted to point out that it is possible to mount them that way.hope this helps.
