Swerving=Not fun

Parkins · 06-09-2009, 12:40 PM

Heyy...
So I recently bought an '86 and have done the suspension bushings (all except the steering one), new tires, alignment, and some other engine maintenance stuff but my car will kind of swerve in either direction on the highway when I'm going fast. It usually happens on the less smooth roads... could this be the steering rack? wheel bearings? sway bar? everything under the car looks fine...
any ideas?
thanks

I believe the steering rack bushings are usually referring to the inner rack bushings. Don't people replace those to get rid of clunk, not play?

If you have straight-line tracking issues at highway speeds, sounds to be tie-rod ends. Did you replace those? (yet)?

What were your final alignment specs? Did the shop say anything was loose, but proceeded with, or were directed to continue with, the alignment anyway?

sounds like an alinment issue to me....that or one or more bad balljoints.

Ball-joints most likely I've been doing my bushings recently and noticed that one was shot.

i had the same problem and it turned out both my rear wheel bearings were shot.

didn't think about the wheel bearings, It could be that also...the only way to tell is to get the car up in the air and start shacking tires.

I did not replace those. I'll have to look into that, thanks

They did say the steering rack was loose... is that something I can tighten or need to just straight up replace?

I do have a small tear in the driver side front ball joint... I have been meaning to replace that.

I was thinking that. I'll have to look into getting some. Any recommendations for good prices?

Parkins · 06-10-2009, 12:59 PM

they also told me my camber on the back is right at the limit

Parkins · 06-13-2009, 10:44 PM

replaced the rear bearings today and nothing changed...

could it be the whole bump steer thing???

What about the rear toe adjustment bars? Drop them at the subframe end and have a feel of the bushing, my SC mkI started doing elliptic circles when those wore out and it wandered all over the place. They were giving the wheel huge play, might as well have been a bolt floating in a 1inch hole.

Jack up the car and shake each wheel back and forth, as well as up and down. It sounds like it may be a ball joint or wheel bearing issue. I had a ball joint go bad on my mkii and whenever I went above around 45mph, if I wasn't in a corner the back end would weave frighteningly back and forth.

Parkins · 06-14-2009, 03:55 PM

all of the suspension bushings are new, but i'm starting to think it might be ball joints... 2 of them have tears (one front and one back)... I'm thinking I might just go and replace all of em since they arent too expensive...

ZIELINSKI · 06-14-2009, 07:21 PM

Just a question... What size wheels do you have???

Parkins · 06-22-2009, 01:06 AM

I'm not sure right now and am too lazy to go look... its dark...
stock I'm sure though...

I'm worried its an issue with the steering rack... thoughts?

Doubt it, they may get some play in them and clunk a bit but they shouldn't cause swerving. The only true and tested way to find something broke is to go look for it. We can suggest things but ultimatly you have to find what is misaligned or sloppy, it may not even be anything we have said.

Full day poking everything suspension related and looking for play and you should find something.
