10-02-2017, 01:14 PM #1hi all-brief rundown of work so far completed in an effort to stop knocking noises - 2 x front discs and pads,2 x upper balljoints , 2 x lower balljoints , two droplinks , two front shock absorbers - many knocks gone but still cannot live with noise on rough roads-its down to an occasional knock and a low kinde clap/thud which im hoping is arb bushes which have been checked untold times but in the process of elimination its the next logical step - does anyone else recall problems like this or the cures for travelling on less then perfect roads-as most are-and is it just one of those characteristics if the is200/300

10-02-2017, 01:24 PM #2yup spare secure-jack secure-nothing loose in boot - noise coming from front and can be loud-pedestrians jump in surprise loud sometimes-- not what i expected of a lexus tbh - i was gonna go as far as topmounts then admit defeat as not having a lot of luck with the lex in general but that also kills the only other car i want - the is300 as it could suffer similar problems-mind you i read steviewievies build thread today and it shows admirable patience-which i could learn - i just hate the look the gf gives me every time i spend money on this issue and its not cured --i adore the car in nearly every other way though so would be a shame to give up - ive spent about £1800 on it since jan-oh if the weather cheers up at the weekend im going to strip the front brakes and service the pins etc and check the spring has good tension on it
Is the noise from the front or rear ? You haven't got a broken ARB have you ?

12-02-2017, 05:02 AM #5update-had the oem arb bushes fitted today with some improvement in noise over potholey roads - while the car was in the air i noticed some bolts missing here and there from the plastic shrouding running down the sides of the car underneath which i have come home and replaced/retightened there still seems to be quite a lot of "flex" in these side panels even though they are tightly secured which does sound a bit like it could be the cause of the funny "widga board" kinda noise i have been trying to eliminate - do these underneath side sill type plastic shrouds serve any urgent purpose or are they an integral part or bolted to anything i should be aware of before i remove them to see if the noise in question is caused by these ?

12-02-2017, 05:21 AM #6One of those plastic sill cover things broke in half when I was driving once, which was a real pain. I just took it off, after Stav had told me he'd removed his. They just help keep the underside clean. I suppose it helps stops road salt being splashed on there, but it's all protected anyway.

12-02-2017, 06:32 AM #9going out to mcd in a min so ill see if tightening it up has helped at all - would be my luck that two 10mm nuts and a loose bit of plastic would cause me to practically replace all the front suspension links etc - still its good to have a tight front end i spose

24-02-2017, 10:58 AM #10update - had my underneath side sill plastics removed today which were certainly making some noise over rough roads as evident by the lack of it afterwards - i can only presume that after a certain age these plastics loose some of their original rigidity and become more flexible then when new
