I have lower on spring, have camber arm installed and alignment done. I have noticed this on my 05 when going straight on flat surface. I have to hold dead the steering wheel in order for the car to go straight. so the steering wheel is completely centered. but i have to hold it and if i let go the st wheel, it will slightly turned to the right ... like maybe ~3-4 egrees or so.
which mean when im driving on highway, i have to keep pushing up with my right hand or pulling down with my left hand so that i wont go to the right line....and its super annoying

i did some search but most of them was the steering wheel not centered and i know a alignment can fix it.
so should i get the alignment redo? i just dont know where is this problem come from, alignment or something else??

 

Check your tire pressure...

 

Alignment issue. Just because it was aligned doesn't mean it was done right.

 

tire pressure was checked during the alignment too.

 

OK, so its just a alignment issue, not something else??

 

It can always be something else but it seems most likely that it is an alignment issue. Other options would be a stretch.

 

It could also be what is called in the business as a radial tire pull.Very rarely tires are not checked for radial runout(mostly cheap tires) theses days and that could be the problem if the alignment checks out ok.

 

its the alignment. Public roads are not perfectly flat. There slightly slanted to the right to for drainage purposes. Usually most alignment shops add a little bit more caster to compensate for the slant.

 

Unfortunatley caster is an adjustment that cannot be adjusted anymore on over 95% of the cars still on the road.

 

i see, i didn't know the g35 didn't have caster adjustment. My mercedes had caster adjustment stock, so i assumed the g35 would too.

 

check if tire is good and if it is properly balanced.
Darkstar mentioned, just because it was aligned, it doesn't mean it was done right.
take it back to where it was aligned and let them know it still pulls to the right so they can fix it.

 

thanks for the input!! im going back for a realignment and will let you guys know the outcome!
