Angry Can't keep it straight

I need some help with a problem that I have been chasing for over a year now. The Bird wanders around on the road. It tracks straight but the least amount of uneven pavement and away it goes. You can't take your hand off the wheel for a second. I started with L & R new upper and lower control arms, new front and rear hub bearings on the passenger side, a couple of alignments, and new tires to no avail. The only thing I haven't replaced is the strut rod bushings and the driver's side bearings, and shocks. The tech said I need a camber kit for the passenger's side front but it was probably ok with a driver inside. I know it isn't the rubber steering joint and am wondering if it might be the rack or even the PS pump since I have the speed sensitive steering. I have replaced both sides tie rod end (inner and outer), and no improvement. I did find the rear toe lnks busted and replacement made no chnge there either. I am about ready to ditch it as bad as I hate the thought. Anything I missed?

Thanks,

'Sounds like it doesn't have enough front caster. The more the caster, the more it wants to keep going straight.

that's what happen to me too. with the stock tires it is barely noticeable but after change to wider and lower profile....both my 94 and 96 have the same problem.

this may open up to a new world of discussion.

Same problem here and the car pulls left. My car is lowered and I run 255/45/17s. I have been all over this thing and can't find a problem. I have aligned it 4 or 5 times and set the caster 1/2 degree more positive on the passenger side and the camber 1/4 more positive on the drivers side, but the car still pulls right. Changing the alignment does not seem to have any real effect on it. I will take another look at the front suspension tonight (for probably the tenth time), but I have replaced the lower ball joints, strut bushings and LCA bushings. The only thing that helped was the lower ball joints because they were obviously bad. I think it is because either something is worn or bent or the car is too low and suspension has poor geometry at this ride height. It is hard to spot a bad balljoint in these cars because it is very hard to unload the front suspension. My method is to get jackstands as far out on the lower control arms as possible and then jack up the back end. Then try rocking the tire around with a six foot 2x4 in every direction. Lower ball joints seem to take a beating theses cars. That's my two cents worth....

when I went to get my car aligned, the shop couldn't even get it in spec. They told me it had been in an accident. Imagine my surprise! I think I'd have noticed something like that

I'm running stock tires etc, so thats not it. I am begining to wonder if the alignment shops are trying to sell more tires because they tried hard to sell me a new set claiming mine had bad belts. That mayhave been true as replacing two has helped but how long before I start seeing weird wear patterns and wandering again?

I'm running the tires that came with the wheels...they're none too spectacular, and not in the greatest shape, so new tires might help. I wonder why they thought my car had been hit, though. Everything looks fine underneath...

Prior to my suspension upgrade, my 94 would do the exact same thing. Before the upgrade I replaced the rear shocks and it helped a lot. Surprisingly so!!

Post-upgrade it is doing it again, but I have poly bushings everywhere (which makes everything “tighter” and the same cheap POS rear shocks (which I think have already gone to the great shock haven in the sky).

I have new shock, but I haven’t installed them yet.

Have you checked your rear bearings? Both of mine went out and uneven pavement would make the car pull, jumping off the gas would cause it to pull. It bacame a 2 hands on the wheel driver. My wife thought I had too much too drink one night because on one road I was hard to keep off the center line. The passenger side was very noticable by jacking up the car and moving the tire around, not so much on the drivers side. This had been happening gradually, but was acelerated by change to 3.73 gear. With new bearings and hubs on both sides I can drive with my knee if I want too.

well, I have the same problem - sorta' -
If I allow the steering to return on it's own, it won't go all the way to dead centre - rather it will be a little off to the side I was turning
i.e. made left turn, it's slightly off to the left
i.e. right turn slightly off to the right.
So maybe your steering might be doing this?
Just a thought, I really don't have any clue but it is possible that your steering may not be quite centred -
Who knows, your steering wheel might even be uncentered slightly?
Again, just some stuff to consider...

I figured I would post what I found was my problem: loose hub retainer nuts.

I blew a tire last week and when I was changing it for the spare I noticed that the tire had a good 1/4" of play. I thought the new bearings had somehow gone bad. But when I went to change them out I found out that the nuts were loose on both sides.

I tightened them up to the torque spec... again... and now it tracks great. (I have new nuts on order).

Just thought I would post my "discovery".

No luck yet. The only thing I haven't replaced is the shocks, Rack, strut rod-frame bushings and the driver's side hub bearings. I am begining to think that the strut rods are the culprit as I've noticed I can spin the washer between the nut and shell. I'll check in later with results.

I have similar problems as well, I have to keep the wheel slightly to the left to go straight, but for me, new suspension parts are in need. So after that I'll see if i still have the same troubles.
As far as a solution goes I think it will be different for everone since there are a lot of combinations of things that seem to cuase similar results for everybody.

Jack up the back of the car and see if any play in the rear wheels. Better yet, take off the tire and see if there is any play in the hubs. Like I said in up in this thread, sound like rear bearings. Very noticeable when both are bad, not that bad when just one.

First things first, if anyone EVER says anything about a camber kit for our cars, say thank you, and get out of there as quickly as possible. Clearly this tech has no idea how to align an MN12. Take it somewhere else.

My 95 used to pull ever so slightly to the right, we never did figure out why. It did it from day one until the end. I'm also interested to find out why.

i fixed mine. by changing the lower control arm and strut rod bushing. i'm thinking it's my strut rod bushing because my lower control arm is still very good at both side and my strut rod bushing are shot to hell.

i still change the lower control arm because i already bought the parts and already taken the old one out from the car and say damm, what a waste. since it's out, might as well change it. the strut rod bushing is another story, well, it's shot to hell.

my guess would be the strut rod bushings, if they are worn i would think you would loose some caster, somebody correct me if i'm wrong but since the strut rod bushings blew on my 92 it wanders all over the place.
