Hard to believe that a 7.4 vs. 7.2 diff in caster is that significant... MarcW - Tuesday, 21 February, 2012, at 3:23:14 pm |

Just had an alignment after my drive axle replacement and now have a slight pull to the right. Tech set all toe F/R to middle of range (.05 front, .09 rear) but camber was set to minus 1.8 deg rear L/R and minus 0.4 deg front L/R. (seems to be right at edge of range) Tech claims that the pull is due to the (unadjustable) caster which is currently 7.4 deg L and 7.2 deg R. Michelin Pilot Super Sports are virtually new with ~1K miles.
The pre-alignment setup had +0.4 deg LF camber and -0.4 RF camber. (not a typo) I'm guessing that this somehow compensated for the unadjustable caster offset to eliminate the pull. (car used to be dead straight, and tire wear was fine) Tech suggests keeping the alignment "square" (as is after the new alignment) for better handling. They will be glad to reset to the previous camber if I desire....we agreed to drive it a few days and see. For me the slight pull is too annoying....not just due to the road crown. I was fine with the factory alignment setup.
Has anyone else had similar issue, and if so what did you do? Is it conceivable to eliminate the pull just by tweaking the front camber?
FYI, shop was Autoscope Park Cities in Dallas, a well outfitted 3-yr old facility that has served me well in the past.
Thanks...

A statement that one has never seen a car do xyz is just a flip of they all do that... MarcW - Tuesday, 21 February, 2012, at 6:01:27 pm |

the shop claims that he's never seen a boxster have a pull with the alignment setup that he dialed in, so if true, my vehicle is an outlier. Also FYI, my 7.4 and 7.2deg caster readings are both slightly beyond the factory 8deg +/- .5deg. (I had a dealer shoot me the factory settings list...)
Like MW said, no better than, "They all do that." *NM* Laz - Tuesday, 21 February, 2012, at 6:25:55 pm |
