car going left and right on straight line

[drill]

dear frens,

one of my car, a 97 ford lynx had undergo some restoration recently.

i've change:
- front tyres
- all four absorbers (tokico japan) standard oem including its cushion bushings an cover
- all absorber links
- all bushing for lower arms front and rear
- rear original stabilizer bar bush
- tie rod end
- and redo front and rear alignment

now my car got problem, when going straight, suddenly my car goes to the left or right a bit, but my steering is still in straight position. when taking corners, a lil bit more horror. let say im going down from a flyover, turning the steering to the left a bit, suddenly it goes like over-steer ( front of my car turn more to the left than what i intended to.

i checked my recently changed steering rack and its bushing, seems to be ok.

opinions and held needed.

could it be your chassis problem?

cant be.... it never happened before i change all this.... also never had any major accidents before... just minor scratch only...

my foreman says its the alignment.. but i cant 100% agree with him since if driving in straight line, the steering sit still in its position.

try look at tie rod end, cv joints and lower arm bushing too....no guarantee will solve yr problem but it happens to my saga many years ago BUT since u changed all the above...maybe yr tires & alignment...sometimes even new tires also possible to swirl left n right

Toe and camber problem?

u got do allignment & balancing anot? & adjust yr camber too.....
cos wat i suspect previously your tire already makan one side....so therefore yr car will not go in a straight line.

Thanks guys for the replies. yes i did the alignment and camber adjustments. tyres also new. so i think no issue with tyre makan one side.

i agree with EvolZ, but i have clocked almost 200km since i changed the tyres, so if tyres is the issue, it should be gone by now i guess...

today i think will try another shop to check out the alignment. any recommendation?

Guys.... Ive went to 2 tyre shop today. They check the alignment... Both said ok. The last shop check all bolts, all are secured properly. Rotated the tyres, redo balancing.... Still the same. Owh btw, the last shop used manual technique.

it cannot be the alignment din, sounds like a steering rack related problem. need sum checking?

yes... just had it check... the rack had no leak and the pump was working nicely. and i did mentioned earlier i had rotated the tyres.
