*CLUCK* sound when steering? Hello fellow RS'sers, My IS300 makes a *cluck* sound when its steering at very low speeds. Funny thing is that it doesnt happen all the time, it comes and it goes. It was making this noise in the fall, then it sorta disappeared, and today, its come back again. So the situation is this, say I'm parallel parking, or reverse parking into a stall, I've stopped, turn the wheel and start moving again it makes a *cluck* sound coming from the front. If I got to pick a side, its probably coming from the driver side, but I'm not sure :confused::confused:. Anyone have an idea what this may be? The car is factory lowered (has the L-Tuned Eibach lowering springs), the struts will need replacing soon, don't think the previous owner changed them, the car has 145k-ish on it. |
well, the design of the suspension on the Lexus's are not like that of the honda, where the strut turns and twists with the car when u turn the steering wheel side to side. on the lexus, the strut is mounted between the upper control arm and on the lower control arm. thus it should only go up and down for movement and no real twist to it. the hub turns via a lower ball joint which has a tie rod attached to it. the lower ball joints on the lexus's are known to have failure anywhere around 100,000 miles to easily double that. so i would look into replacing them. if i remember right, they should be around $150 or so a side. and labour involved is anywhere from 1/2an hour to an hour a side to swap out and replace. |
sounds like you may have a chicken caught in your steering rack. do you live in abbotsford? |

check the inner and outer tie rods....and check the bearing on the struts or i could be the struts itself.... |
Weird, now it makes the same cluck sound when i go over a small bump in the road or a speed bump, but only at low speeds. Does this sound like the struts? |
maybe but the best thing to do is go to a shop to be sure and if they find anything make sure ask them if they could show you the problem..... |

Hope this may help somebody in diagnosis. |
i agree about the stabilizer bar, check the bushings and make sure they are still intact. if you've ever driven a car with bad bushings it makes clunking sounds and you can feel it through the steering. |
on the way to whistler one night, i heard a clucking sound while driving, turned out to be loose lug nuts. i forgot to torque that side when i put on my spacers. thats the only cluck i can think of. |
is it at full lock? I don't know jack about your front suspension, but the turn knuckle bump stop caps may have fallen/worn off. do you notice the front of your car dipping down when you turn the wheel to full lock (when fully stopped)? the caps are a couple of bucks each. |

After a few months since I replaced the endlinks, the knocking noise came back. So this time I lubed the sway bar bushings and this seems to help A LOT. I no longer hear it anymore. I guess it was the bushings being dried up and so the sway bar wasn't able to move freely. Note to self: Keep the sway bars bushing lubed frequently. |
the funny thing is i get the clunk sound because i swapped sway bars and the new bushings are poly and i lubricated the crap out of them. there is so much easy movement that they are making the clunking sound... |
After a few heavy rains and lots of puddles on the road, I do hear the cluck noise again. But its not as loud, or as often. I posted this because a lot of people forget that sway bar bushings needs to be lubed regularly as well, like any other maintenance. I was one of them. =P |
