I wonder what is car leg means in english, anyone can help me?

Is it suspension? They said if car accident at front, the "Car Leg" will be "kemek" and cannot be repaired until as good as before and it will affect the stability of the car either high speeding or cornering.

Is it true?

from da damage i c is not very bad~
jus mayb ur new abs tat u claim tat day might bend a bit~

car leg = lower arm

accident, ur lower arm sure bengkok lar... thats why have to change new lower arm lor....

lower arm can be changed? The workshop that repair my car said lower arm bengkok ad, repair ad also got difference, he said cannot replace a new 1.

i think tat fella taking crab lo~
who said lower arm cannt change? ?

Can be change, my friend just changed his on his spectra. Seek for other workshops.

Lower arm can be change.. last time lower arm loose, when drive fast the steering like turn like snake.. but now tighten jor.. smooth ride

TS, what car r u driving?

sgti~

hermm.. sgti, the connector to wheel only absorber, tie rod end (from steering), lower arm etc forgot la..
but if lower arm just replace with new one or get from chop shop cheaper, maybe sgti harder to get coz it's not the same with normal wira/satria/putra..
not so sure either it same or not with wira/satria/putra..

sgti lower arm compatible with evo ones??..

evo one also not sure izzit the same with sgti, but what i know evo's the shape of the arm really look tough compare normal wira one...
n how about mivec i dont know..

wow, got car leg wan ar?, car hand is what?

direct translation from chinese lar bro.... mechanics all not varsity graduates... u talk to them technical term they sure kantoi.... must learn layman's term when u go workshop...

car leg actually means automobile's undercarriage, to be precise.

undercarriage consist of shock absorber, steering tie rod, steering tie rod end, knuckle arm, lower arm, drive shaft, trailing arm, etc...

satria GTI's undercarriage design is exactly like proton wira where the front suspensions are supported by one Suspension Crossmember Front. If replacement to the lower arm does not help, probably the suspension crossmember front is bent too.

if front crossmember is bent

good chance the chassis beam is bent

better check your chasis if there's any deformation
for me the best place for checking is to bring your to the panel beater

brader... sgti uses macpherson struts in front ler... it is an independent suspension.... dun have crossmember geh....

then tell me the lower arm is mounted to what?

the workshops I go to, they have to explain to me properly.. or else show me what they intend to do/repair.. if not able to convey that clearly even in Cantonese etc, or else probably avoid that place..

Added on September 21, 2008, 11:44 ammaybe he meant the "member" holding the lower arm in place.. it doesn't move, not a part of the movable suspension, just the anchors to bolt the bushings on to..

lower arm mounted to the chassis....

wah really got photo, kheng!

LOL, thats only 1 side of the lower arm.

what about the other end?

all car also have crossmember la..if not how u mount you engine/gearbox/steering rack?

the other end also connected to the chassis ler... where to torsion beam across left n right for macpherson struts....
rear suspension got lar... like myvi, vios all using torsion beam axle....

oh soli... not cross member... crossmember is the centre batang under ur engine bay which supports the engine/gearbox...

u really have to stress this..lol

if u drive vius and bent ur torsion beam..u can just buy 3" water pipe from hardware shop and replace it

oh... soli... correction..

vios, myvi those are using multi-link beam axle suspension for rear setup.... front i guess should be macpherson struts as well (couldnt confirm)....



nowadays mosts cars are having either macpherson struts or double wishbone suspension for the front....

macpherson strut diagram.... found in most compact FF cars....



double wishbone suspension... found is more expensive / sports car...

this kind leg look more sexy

somehow, I wouldn't call those rear suspension as multilink, more like "trailing arm fixed beam axle", i.e. when right side move up/down, the left will be affected.. i.e. not independent.. due to the lateral beam connecting the left and right side hub..
multilink should be used for Independent type suspension.

there are many names used to refer undercarriage parts.

anyhow, to enlighten people here, the crossmember that the_catacombs mentioned about is found in Proton Iswara / Wira / Satria / Waja. if refer to EON's spare part catalogue, they named is as Engine Support Member.

the crossmember i was emphasizing is horizontal at the left and right chassis. this is called the Suspension Crossmember Front which mounts the lower arm.

for the rear suspension, that piece which some foreman call it the drumstick is the Trailing Arm.

if u see under a macpherson strut suspension, there is no centre 'crossmember' hold the left and right side of the front lower arm... left and right lower arm is independently bolted to the chassis...



trailing arm is what old saga iswara is using as its rear suspension...

FYI, only the Iswara / Saga that doesnt have the Suspension Crossmember Front.

sure is lower arm? Cause lower arm can be change.. Since you driving SGTI, go half cut and get evo 3 lower arm.. It lighter and more solid.. As I know, all the part inside a car can be change.. Only chasis cannot be change..

this kind of arm is semi independent, each side suspension can move independently but the camber remain fixed under movement..this old tech seldom used anymore..a bit similar to the trailing arm in kancil

the one in vius is torsion beam which mean either side movement will affect the other, added the absorber and spring made from jelly, one side camber added will reduce from the other side..

How much is that crossmember for satria that supports the engine/gb.. chopshop & new?

i thought wira and saga also using similar macpherson struts....

wait i go under my friend's wira peek...

yeah, you should go take a better appreciation on it.

The crossmember is part of the lower support for the engine (also known as the lower engine mounting) in wiras,satrias and putras.It doesnt connect to the suspension as catacombs has shown in the pic with the iswara/saga.Independant mcpherson bolts to the chasis if im not mistaken.

As for david,yes the arm can be replaced but new ones cost quite a bit.The last time i checked with proton,a set would easily set you back rm450 without installation.(Bear in mind this is the "dead" arm used on iswaras where the rear arm is fixed and is not adjustable)
Chop shop ones cost in the range of rm120 - rm250 depending on age and condition.

For wira crossmember,cap ayam is around rm80 and Ori ones will cost around rm200 with installation.This was 3 yrs ago.Chopshop i didnt check

do u have pics of the so-called crossmember u mentioned??...

if not, i have... pics of the lower arm bolted to the chassis... and not ur so-called crossmember...





how come i dont see any part of the lower arm connected to ur so-called crossmember??..

take note the crossmember in between the driveshaft and steering tie rod.



notice the lower arm mounted to the suspension crossmember front?

sibeh hard to see...

anyone got proper direct picture can clarify this arr??... i not vr expert in seeing angled photos...

My car's right side lower arm bent already, so have to change.

He said only lower arm got problem.

Is lower arm bent consider as something serious? A lot of peoples said, once lower arm bent, no matter how you repair or change it, your car still won't be like before anymore, sure got sound, high speed sure got difference. :S

Really worry now.

yup lower arm bent quite a big problem..as the arm attaches to your wheels and thats what keeps the car on the road..it can cause skidding and loss of control thru corners..my personal experience..get it changes asap

You mean eventhough I change it, it still can cause skidding or loss of control through corners?

erm no..if you completely remove the arm and replace it will sort the problem out..because if the arm is bent,one tyre will not be facing forward in the direction of drive.my back arm was bent so the car will skid and slide around..but its quite costly la..

Sorry, digging out an old thread, for satria, the lower arms are mounted on Sub Frame, while the old Saga don't have sub frame.

for wira, satria, putra, lower arm are mounted on suspension crossmember (some workshop call it subframe, some call axle, some call butterfly because it look a bit like butterfly) Suspension crossmember, mount on chassis frame. if your lower arm is bent, there's a possibility ur susp crossmember, and stabilizer bar link rod (some w/shop call it satay) bend too because all of this parts is mount together. all of this parts is change-able. some people comfuse between suspension crossmember with engine lower support member. clear?
