Just changed my Springs and Struts and also my top strut mounts on front and rear of my my TL Type- S and im still getting this nasty thud sound. Anyone have a clue on what it can possibly be?

 

were you getting the noise before this install? ck the sway bar end links and all the suspension and steering parts-bushings

if new noise- are the front and rear springs on the correct ends of the car- they have been install wrong before~

new noise: are the top nuts that hold the sping and shock together tight to spec
How exactly did you tighten them? air gun?

 

To Behonest I didn't think that Specs had to be considered because of did this kind of job on all of my cars and never ran into a problem like this.. and yes it was making the noise prior to me changing the spring and strut. However I will look into the sway bar links from the front right and left, i don't know why i never thought of that. Do you know where I can get those tightening specs for the Struts?

 

dont know the exact spec--always did it with an air gun --blasted on is good!!
I was just making sure you didnt tighten with a hand ratchet and think it was tight = leading to thumping

Moog brand end links are way better and easier to install the stock units

 

o ok yeah i did it with a Gun.. and ok ill letchu u kno the results after installment. once again greatly appreciated.. if u have or can think of some other reasons that can cause it to make the noises just let me know.

changed the sway bar links... light improvement made but i still have a nasty knock... but i did discover that i need to change my right wheel bearing in which im going to do soon.. so hopefully eliminates some of the sounds

 

check your lower ball joints too.
