Sway Bar

[just4u]

pina-service namin ang Dodge Caravan sa dealer for a change oil... okay naman pero they said something about replacing the Sway Bar... ano po ba ito mga tsikoteers?... ano ang probability kung bakit kelangan palitan ito... napansin ko lang na tuwing dadaan sa medyo malubak medyo maingay ang gulong pati na rin sa humps kung pabigla ang drive....

di ko pa naman pinapapalitan pa kasi mahal sa dealer at saka pabiyahe kami, pero hanggang kelan ito tatagal without replacing it.... nagagamit pa naman ang van pero medyo alanganin ako kasi wala akong alam sa sway bar na ito... kung di naman papalitan kaagad, lalala ba o ano ang madadagdag na danyos?

pasensiya na at di ko gaanong ma-explain ang problema pero if you can spare some ideas about front sway bars, I would very much appreciate it.... thanks in advance

A sway bar also stabilizer bar, anti-sway bar, roll bar, or anti-roll bar,ARB is an automobile suspension device. It connects opposite (left/right) wheels together through short lever arms linked by a torsion springs. A sway bar increases the suspension's roll stiffness -- its resistance to roll in turns, independent of its spring rate in the vertical direction.

i think you will have to replace the sway bar linkage.. not the sway bar itself.. i dnt think you can drive a dodge caravan so extremely that you will break the sway bar,

Anti-roll Bars (Sway Bars/Stabilizers)

No, these aren't the things that are bolted inside the car in case you turn it over - those are rollover cages. Anti-roll bars do precisely what their name implies - they combat the roll of a car on it's suspension as it corners. They're also known as sway-bars or anti-sway-bars. Almost all cars have them fitted as standard, and if you're a boy-racer, all have scope for improvement. From the factory they are biased towards ride comfort. Stiffer aftermarket items will increase the road-holding but you'll get reduced comfort because of it. It's a catch-22 situation. Fiddling with your roll stiffness distribution can make a car uncomfortable to ride in and extremely hard to handle if you get it wrong. The anti-roll bar is usually connected to the front, lower edge of the bottom suspension joint. It passes through two pivot points under the chassis, usually on the subframe and is attached to the same point on the opposite suspension setup. Effectively, it joins the bottom of the suspension parts together. When you head into a corner, the car begins to roll out of the corner. For example, if you're cornering to the left, the car body rolls to the right. In doing this, it's compressing the suspension on the right hand side. With a good anti-roll bar, as the lower part of the suspension moves upward relative to the car chassis, it transfers some of that movement to the same component on the other side. In effect, it tries to lift the left suspension component by the same amount. Because this isn't physically possible, the left suspension effectively becomes a fixed point and the anti-roll bar twists along its length because the other end is effectively anchored in place. It's this twisting that provides the resistance to the suspension movement.

If you're loaded, you can buy cars with active anti-roll technology now. These sense the roll of the car into a corner and deflate the relevant suspension leg accordingly by pumping fluid in and out of the shock absorber. It's a high-tech, super expensive version of the good old mechanical anti-roll bar. You can buy anti-roll bars as an aftermarket add-on. They're relatively easy to fit because most cars have anti-roll bars already. Take the old one off and fit the new one. In the case of rear suspension, the fittings will probably already be there even if the anti-roll bar isn't.
Typical anti-roll bar (swaybar) kits include the uprated bar, a set of new mounting clamps with polyurethane bushes, rose joints for the ends which connect to the suspension components, and all the bolts etc that will be needed.

Ilang taon na ba yung Caravan ninyo?

there's one time, nag-drive kami papunta sa isang parking area, madilim iyong lugar tapos biglang may malalim na area pala.... hindi ko alam kung isang cause iyon... I'll have to double check with the dealer kung linkage lang ang papalitan or iyong buong bar... thanks for your added info, sir...

[just4u]

Ilang taon na ba yung Caravan ninyo?

5 yrs. na...

[just4u]

thanks emongedmund and mbeige for the explanation...

ang tanong ko ngayon, puwede ba munang patagalin iyon atsaka paano ko malalaman kung nag-snap na ang bar... wala pa kasing budget dun pero di naman nagagamit ng malayo ang sasakyan.... at the most 100 mi. a week lang ang gamit nun...

maraming salamat ulit...

[t2erns]

sa tagal ko na gumagawa sa chrysler sir wala pa ako nakitang nag snap na stabilizer bar, ang nasisira lang madalas ay yung mga bushings and the links, control arm bushings, the strut, strut mounts and mga steering linkages and ball joints.

[speedyfix]

most likely the stab link lang yung busted dyan.

[mazingerZ]

Sirs,

Question rin po, when I had my vehicle serviced sa talyer, the mechanic told me that there is already a small "play" sa stabilizer bar ko. What are the effects of this "play" sa driving experience ko? Although sabi ng mekaniko there is still no worries pa. Thanks and God bless.

[abort_retry]

the oem stab link is expensive. but there are also replacement stab link which goes more or less P2000/piece in binondo.... its fairly easy to replace and any suspension shop can do it for you....

[speedyfix]

it will normally manifest itself in noise over small bumps. kung wala pa naman then it should be ok pa.

[mazingerZ]

Sir speedy,

Like kalampag na noise?

[speedyfix]

yup kalampag and a knocking sound.

[mazingerZ]

Okay, Thanks sir speedy . .

pasensiya na at ngayon lang nakapag-update... I brought the van to another service center - ang gustong palitan : shocks in both front tires... atsaka struts at the rear...

tapos, I called the Dodge dealer and asked them again what they wanted to replace - sway bar links and bushings.... pasensiya na kayo at di ko naklaro ang problema ng van...

ngayon mas naguguluhan ako... alin ang dapat palitan?... ang na-eexperience ko kasi pag dina-drive eh maalog at katok ang gulong sa harap pag- dumadaan sa konting lubak...

ano ba ang pagkakaiba ng links, bushings at shocks and struts... paki-explain naman po....

[speedyfix]

shocks and struts are probably the same thing. easy to check the sway bar links naman. just unconnect them and test drive. if the noise is gone then replace them.

sa shocks naman you have to uninstall them to see if ok sila or not.
