Thread: suspension knocking sound

2005 grand prix gtp comp g
160000kms

Hey

Im having a weird knocking sound on the driver side when i drive over any little bumps, its pretty loud too. It sounds as if the stabilizer link came lose on one end and was banging against the strut or control arm. I replaced my lower control arms with ball joints last summer, As well as stabilizer links and strut mounts. i used moog parts for everything so i do not think anything has failed, and the only other worn part i have the parts for but never got around to replacing is the inner and outer tie rods on both sides, could they be the possible cause? steering seems unaffected.

i rocked the car in my driveway pretty good and was not able to recreate the noise, So i do not think its the strut,
I am trying to avoid having to jack it up and pull the tire off, There is still a foot of snow in my driveway.

K i have it jacked up now with the tire off, there is no play in the wheel, sway bar/stabilizer link (same thing as far as i know) looks good, they only have about 8000kms on them, couldnt find play in anything, tried with a prybar, only thing i saw but i doubt is the cause, The lower control arm sits close to where the bottom bolt for the stabilizer link bolts in, they could touch but not over every little bump i hit, and its the same on the other side so i doubt thats the problem.

sub frame bushings are good, trailing arms i will be replacing this summer but they are not that bad. The noise is isolated to the front driver side tire, was able to test it going over speed bumps, I am leaning towards a possible strut issue.

I know the comp-g came with stiffer suspension then the other GTP's, i was thinking of just buying zzperformance strut/spring combo with the gr2's. the struts i have now are completely stock, other than the mounts, so need to be replaced anyways, anyone know of a better pre assembled strut option? or is zzperformance gr2s good enough?
