knocking sound coming from the passenger front.
 

ok so i recently lowered my 1990 supra with lowering springs. Replaced the front struts and springs and the rears. So now...i noticed that when i turn hard left...like when i want to go into a drift, i hear a loud knock knock knock sound. and ive been looking up on sites of other peoples issues, but all there cars are fwd....yuck, so can anyone help??

my car does the samething but myn is not lowerd

How long has urs been doing that??

the one im driving now since i got it like a month ago haha.
my old one did it too i have no idea what it is....but i know itas not the lower ball joints haha

think it could be a bearing of some sort? and how do u kno its not the ball joints????

i replaced both of the thinking that they were the prob. but after i replaced them it was still making the noise. I think it may have somthing to do with struts, im too poor at the moment to replace them to figure it out haha

Well I just replaced my struts so it can't be that, unless I somehow got a bad one

hmmmm....well that knocks those off my list haha(people were telling me its prob those) have you taken a look at your bushings up front?i would but im at work right now

Not yet, im actually at work too lol but I have a feeling its one of those

alrighty leme know what you find haha

I like how nobody works when they're at work lol

When you changed the struts, did you check/replace the strut mount bushings as well?

sounds like bad control arm bushings possibly.

knocking is usually associated with bad bushings, bad ball joint or bad bearings. all have different variations of "knock" sound.

youd hear a whirring sound at speed and a clicking at very low speeds if it was a bearing. if it was knocking, ud be in some smelly brown stuff (ask me how i know).

ball joints click and/or knock when turning or during suspension articulation, so its possible but if you already checked then ur fine.

bushings will present a heavy knocking noise, especially when compressing the suspension, depending on where the bushing has cracked.

ive had this happen a few times, and normally they arent hard to replace.

the other thing it may be is sway bar bushings so check them too.

if its the bushings, get a prothane front end bushing kit. itll stiffen up the front end nicely and last longer than oem.

I have this problem as well. I read on here somewhere that it could be some sort of "steering stopper". Basically it's a nylon cover that goes over your steering stop bolt. They said that it can fall off or rub off with age. Not sure if I'm right so u might want to look into it some more buddy.

if ur talking about the bump stops, yes there are alot of yotas with them. my truck has them as well. but i get no "knocking" sound from them. more an eary creeking noise, only extremely high pitched and ear piecing.

you can purchase new bump stops online. they dont last long unfortunately.

Check the steering stops. The rubber part tends to disappear after a couple decades allowing things to contact each other with the wheel fully turned. It will cause the noise while driving with the steering wheel completely turned to the lock (you'd either be drifting, parking or doing donuts). Its an awful noise.

that sounds more like myn ill have to take a look, ive never seen these before where are they?
edit: did more research and apparently you can grease them?

yay more people commented! but yea mines only when i turn left....and its a heavy knock, also when i turn right, and turn the wheel all the way it kinda creeks? all the passenger front wheel >_<

lol also, the wheels i have are over sized yes, but Ive eaten some of the plastic wheel well near the bottom and theirs some sort of reservoir behind it. so also steering stoppers?

Think the reservoir is probably your washer fluid tank.

so since its a hard knock would u say bushing? but how many bushings are there?? sway bar bushing....and?

control arm bushings (believe supra only has lower bushings), end links (for sway bar) and sway bar bushings (these mount to the unibody and are the actual "stiffening" point) and last but not least, strut mount bushings/bearings. unless you have the electronic suspension, i believe.

as far as my steering stops go, no, i cannot grease mine. they are a replacable part. here are some from ebay, they are the more expensive ones ive seen.

and i do believe that the resevoir you are seeing is the washer fluid resevoir, as btwilson said.

So also, to add to the madness there's a clicking sound when im driving coming from the driver front wheel. One of my friends seems to think it might just be the caliper slider, because when I press firmly on the break while still going 30mphto for instance it goes away

this sounds more like a wheel bearing to me. does the sound increase frequency with speed of the car?

a caliper slider is only moving when the brakes are applied (unless something is horribly wrong).

jack the car up and spin the wheel by hand. if it clicks while you spin it, id lean towards a wheel bearing. if its never been replaced, they arent bad to at least check, clean and re-pack with grease if not just replace.

yea when i speed up the click speeds up lol how hard is it to replace and price?
