early 911 alignment problems

My 69 911S pulls,hunts,and feels light and jittery after 2 alignments and replacement of worn out Boge struts with used Bilsteins. I suspect torsion bar problems but how do you know without tearing it apart? Any thoughts on the alignment problems? There are no real 911 front end specialists around here. Thanks

Could and sounds like a bent A-arm.

My '85 seems to be the same way. Even after I changed to turbo tie-rods.

I was told, it is because of too much camber.

I have 0 degrees toe, now running only 1/2 degree negative camber. Not sure on my caster.

I think it is either because of my caster, or because my tires are too thin and/or the brand tires do not have a center rib going down the center of the tire. The tires are Yokohama AVS1.

What are your alignment specs?

How are your struts?
How are your wheel bearings?
Can the top of your tire move in towards the gas tank when you push on it fairly hard?

How are your tie-rods?
Does your tire left to right without the steering wheel moving?

Good luck

If your alignment specs are within factory tolerances you might want to check the corner balance. If this is off (sometimes by a bunch), the car will handle strangely even though ride heights appear satisfactory.

If needed, I've got a corner balance worksheet on my site.

I have noticed that the two things that really messed up the way my 86 Carrera handled was a combination of too much caster and too much negative camber in front.

I am currently running about 5 1/2 degrees caster and about 1/4 positive in front and the differnce is unbelievable.

Oh, I had to grind the front of strut plate to get the extra adjustment but it was well worth the effort.

Not only did this make my Carrera infinitely more stable (I can now let go of the wheel and it will go straight) but it also reduced the shaking I used to feel on the steering wheel at highway speeds. I'm also able to whip around corners more confidently without fear of pushing off into the guardrail.

My 69-912 had a similar problem. I had replaced the front struts with Konis and new tires but the handling was still marginal. Replaced rear suspension bushings and still no difference. It wasn't until I replaced the front suspension bushings (A-arms) and both front ball joints and a 4-wheel alignment that the handling greatly improved. All of the old stock rubber bushings (front and rear) had turned to mush after 30 years of use. The poly-graphite replacement bushings made a big difference in handling for me.
