What are some indications of replacing new struts? i had my stock suspension for a while (over 60k)..

I've noticed some small issues that I think, might relate to struts already being bad..

When I turn in corners sometimes I can hear a "pop or clunk" kind of noise .. im sure i need to get it checked but also acceleration in 1st gear sorta makes that sound too.. I guessed that it could be the differential hitting something?? but im not sure.. can someone help ? thanks

Edit:: Will Rear differential bushings help this problem? or would it be a suspension component defect ?

-Kartboy rear differential bushings: Decrease the movement of the rear diff during hard shifts or cornering-
should i get some bushings also ?

 

i saved up and saved up and ordered cobb stage 2 suspension ( springs, front and rear sway bars,) and front and rear combo kartboy endlinks.. does anyone else have a similar set up and would like to imput on suspension feel? Thanks.

 

i think cobb springs work beter on sti struts than wrx. some ppl i talked to had problems after 30k. others went fine for 80k. all your choice homie

put first install the sway bars!

 

i did something alittle different i went with agx in the front and sti struts in the rear. and i have been on cobbs for over a year with no problem...
