Front end clunk question
Hey forum, recently just did my, lower balljoints( MOOG ), inner/outer tie rods (MOOG), and new front brakes/rotors,
(Yes i have been searching the forums and read the whole warning to all gs owners sticky thread about the lbjs)
Before i replaced everything i was getting clunks/knocks coming out of both front passenger side and driver side. Thinking it was the LBJs, I immediately parked her and didnt drive until i could install all the news parts listed above.
After replacing all the parts above, I still have some deep clunks/knocks, sometimes they are consecutive (knock knock knock) and sometimes it is just one knock.
They always occur <10 mph (pulling out of parking spots etc,) & while wheel is turning and usually after or during applying the brakes, but not always.
My question is, what should be my next replacement before i just change out the whole rack & pinion?
front end link sway bars ?
front sway bar bushings?
steering rack bushings ?
or control arm bushings.
I plan on changing them all out, just wondering what should come first. I have a 00' gs300 w/ 138k, lowered on coilovers w/ 19s.
p.s. my passenger side UCA isnt in the greatest condition, so that will need changing out soon too, would this contribute to the knock?
Thank you in advance.

I developed a clunk months ago so I gave the front end a refresh. I replaced the lower balljoints, upper and lower control arms, inner and outer tie rods, sway bar links and bushings. The clunk doesn't happen as much but it is still there. I have given up pretty much. Maybe I'll change the steering rack bushings again one day....... My car is lowered but it didn't clunk when the coilovers first went on years ago.

Thanks for the replies, its a really loud metal to metal clunk, and it almost feels like i feel it in the brake pedal when it happens. Definitely going to check the shims and my whole brake assembly

Mine does the same, it never did it until I put on the left front caster arm bushing (Daizen). So my guess that is my issues. Same exact description, slow speed into out of parking spots, driveway, etc.
As soon as I replace those bushings with factory ones, I'll let you know what happens.

I've replaced every front end component you can think of & my car still clunked. Then I found the problem. It's the brake caliper bracket. For some strange reason the bolts gets loose & allow the bracket to move around. I actually took my hands & can move the calipers with ease. So I took out the bracket bolts & put lock washers on them & re tighten. So far so good no more clunks.

So looked at my driverside caliper today, wiggled my caliper around and it was secure and not loose, so I decided that I would take out the caliper bracket bolts anyways and apply blue loctite, after all said and done, torqued to spec and haven't had the sound yet, so far so good. Hope Im not jinxing myself

Still getting this horrible metal sound. heres a video https://www.dropbox.com/s/n53s7pi5xb...metal.3gp?dl=0
of me on a slope at a gas station (assuming theres more pressure on the front end) and i was able to replicate the sound a couple times. was not pressing the brakes, but this sound usually always happens the first second i lightly apply my brakes while <15 mph.

Still having this issue, if anyone has any other suggestions please let me know, mechanic said he didnt see anything as far as the caliper being seized or the pads not being seated correctly, are the top and botton caliper bracket bolts different thread sizes of something? only thing i havent tried is a lock washer.

I have the same issues as you, and i changed the LBJ and tie rods.
I am changing my front and rear sway bar bushings and also rotors and pads tomorrow night, I will let you know asap.
I got these.

I've done some research and I'm pretty sure its the sway bar bushings.
I am also going to grease my moog LBJ and tie rods while I'm under there.
