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?
