RUCA squeaks???

[bosozoku.s14]

i already searched the forum, looks like people only suggest grease to help solve the problem but it didnt work for me, so i thought i might ask to see if it is something else wrong.

here's the story:

i installed tanabe RUCA for my S14 couple days ago, I started hearing crazy squeaking noise from the rear passenger side i believe. I already grease them today since i forgot the first time, seems like it didnt help at all.

the squeaking noise wasnt too loud, but i can hear it every little bump no matter on highway or locals. im wondering if i did something wrong and what can i do to fix it since it really annoys me.

btw, i have tein ss and spl subframe spacers on my car...

please help me out.
thanks in advance.
