I have a 2001 996 C2 with a dramatic pull to the right. After installing Tarett camber plates and toe links (with bump steer) I had car been aligned by a very competent race mechanic. In attempt to eliminate the pull I have: flipped the front wheels, flipped the rear wheels, disconnected the sway bar control links (one at a time with a test drive each time), had another shop verify the alignment (it is). Where do I go from here?

 

when does it pull?

braking, cruise, decel, accel?

 

Did the alignment shop have a suggestion? I'd have to imagine they'd be able to offer a good explanation if they are competent.

 

Post the alignment results print out.

 

Is the car new to you? Did it always pull or only after the suspensions mods?

 

Could it be a bearing? Any noise associated with the pull?

 

 

Are you sure the car's pulling or that perhaps the steering wheel is not centered?

My WAG has to be alignment (in spite of the fact two shops claim the alignment is ok). The poster who asked to see a printout of the alignment asked the right question. Whenever I fail to get a full printout of the alignment with before and after numbers is when I find the alignment was not done right.

That you have moved tires/wheels around eliminated tire pressure, differences in tires...maybe.

I'm not sure what the results would be if say one (or more) uni-directional tires were installed the wrong direction.

Also, have you closely checked each tire to confirm all tires have the right sizes, tread hardness, speed ratings, etc? Is one tire's date quite a bit different from the other tires?

I find it hard to believe a bearing could be dragging enough to cause the car to pull and the bearing not showing signs of distress (like glowing red from the heat...).

Are the half-shafts in good repair and both attached?

Otherwise I'm stumped.

Sincerely,

Macster.

 

try a diff road.... one that is not crowned.

 

good advice Ferd...look how hard Ferd's car pulls right....in his avatar he has to "correct" the h&ll out of it!!

 

Acel, cruise, some braking

 

Camber -2 (all 4 corners), Caster left +8 1/4, right +8 1/2, toe need to get the actual stat. The tech said it was fine. Need to get to you on that.

 

Here are some current possibilites: possible control arm bushing; however shouldn't be an issue given there is only 52k miles on the car. Corner balancing is another "potential" but would require a corner to be off by 200+ pounds.

 

No noise at all.

 

Macster,

All good points. The steering wheel is centered. My tires are relatively new and sizes are equal. Tire pressures have been cheked multiple times. To totally eliminate the possibility of any tire issues, I have decided that my next step is to take my Boxster wheels and tires and mount them on the 996. Initially I put the Boxster fronts on and there was little change. I gonna do all four. I was also going to check to see if a brake caliper is draging. From there I was going to check my control arm bushings.
