Driving straight is harder then it looks, problem.

I finally hooked up my transmission and took the blazer out for the first time since i've bought it. The problem is that I cant keep it straight. I dont think its an alignment problem because it pulls both ways. I will be driving and it pulls me right then when I correct it then it wants to pull me to the left. Has anyone had this problem before and how did you fix it?

Re: Driving straight is harder then it looks, problem.

Is it stock height or is it lifted? From your description, it sounds like bump steer.

I had that happen to me driving across the country in a 1964 Ford pickup (2 wheel drive). The king pins were bad.

Re: Driving straight is harder then it looks, problem.

its a 4x4 with a 4 inch lift. Just to let you know I am only going 10 mph to test everything out and thats when the this is happening. It will go straight then pull to one side and I can get it to go straight again and it pulls to the same side or the other.

Re: Driving straight is harder then it looks, problem.

Could be a lot of things:

Balljoints (are they original?)
Tierods (same)
Bumpsteer (do you have a drop pitman, or a raised arm on the knuckle?)
Tires (Bias or radial?)

Could be alignment still. If the toe is out of spec, it could pull it either way. Also like others said, it could be worn joints.

Re: Driving straight is harder then it looks, problem.

Re: Driving straight is harder then it looks, problem.

I agree that it is likely an alignment issue. If your toe setting is all out of sorts, then the truck will drive itself all over the road no matter what you do with the steering wheel. Bad joints somewhere in the steering or suspension could also cause it, but I would measure toe in/out before you spend a bunch of money.

For me, I had a tie-rod end which was basically seized. Replaced it and greatly improved the handling.

Re: Driving straight is harder then it looks, problem.

Shouldn't an alignment shop be able to tell you if your joints need replacing while they straighten out the toe?

A quality alignment shop will tell you if there are worn parts. They usually will not do an alignment if there is something that will make it not stay in specs. They would be held responsible if something happened.

What I figured - take it down and see what they say.

Re: Driving straight is harder then it looks, problem.

I just got an alignment and it still is going all over the place. They said that they test drove it before the gave it back to me but still is doing it. I had to trailer it because its not registered. I greased up the tie rods and ball joints and still the same. It seems when it starts one way I turn the wheel and sometimes it doesnt turn right a way. any other thoughts?

Re: Driving straight is harder then it looks, problem.

whenever mine has gotten the road wander blues. It's always been the drag link. And you can replace them without effecting your alignment.

Re: Driving straight is harder then it looks, problem.

when they did the alignment did they put it on the machine and then order parts and then put it back on the machine to check again after installing the parts? and how much was the charge for alignment.

Re: Driving straight is harder then it looks, problem.

Re: Driving straight is harder then it looks, problem.

Some options that I am looking at is that the gear box is to tight or to loose. The Ball joints can be to tight as well so it didnt show up on the alignment. I paid $40 for the alignment. I would like to see some pictures of the shackle to see if thats the problem. ALso someone wrote that it could be the Drag link. I want to know exactly how they thing thats the problem. Please respond.

Re: Driving straight is harder then it looks, problem.

an alignment for four wheel drive is going to cost alot more than that. they have to set it up on the machine take measurements take it back down order alignment parts then put back on the machine install the parts which labor charges apply. it should be more like 150.00 or more. i will take pictures soon.

Re: Driving straight is harder then it looks, problem.

also if the drag link is bent you can not adjust toe accurately. toe does not affect steering it only affects tire wear and if toe is bad enough to affect steering you would see the tire aiming out or in.

Without checking it out in person, all any of us can do is guess, and give you ideas to check out. I'm guessing drag link because I have had to replace it 3 times on mine over the years, and it's the only front end trouble I've ever had with mine. And yes I do keep them well greased. When new they came with a one piece link, but all I've ever been able to find are two piece with a turnbuckle in the middle. But I guess it's just as good. I think the last set ran about $80.00. Good luck, and hope you find the problem.
