Dashing across hump

[Kb27]

It depends on how your car suspension is set up.

If you keep attacking the suspension by going over at high speed, then it will break much sooner.

 

Lateral or side damage will occur.

 

My old van lower suspension bushing didn't last long.

These are rubber insert with metal. They do break if you keep hammering on it.

 

Then you'll have wheel alignment problem, as well as damage to the dampers.

I will always slow down by braking when nearing a hump, and then release the brakes before the front wheels touch the hump. Somehow it gives me an uneasy feeling to have the brake pressurised when going over the hump. If emergency, bo pian.

 

 

 

This is one reason why I will avoid buying a used car if possible.

I'm sure everyone here wants to avoid buying a used car if possible.

Roughly what speed is ok to go over those hump? Some even going at 30+kph still can feel the "pain" of the bone.

Stiffer than usual suspension.

 

I usually go over hump at 30-40

Don't think there's a concrete number but 30 km/h seems a little fast for typical road humps. Of course, different hump sizes, and the car and suspension types play a big part too.

My dad once drove across a hump really quick (his car uses the airmatic suspension). After the hump I warned him its gonna damage the suspension which he said its nonsense.

 

Less than 3 mins later a warning message came up about the suspension, total damage 7k to repair    next time he took the hump he went much slower

hmm...  I saw a lot of Mercs and PHV cars drove across hump without slowing down leh...

[Mercury1]

If they are on normal spring suspension not so bad I think, but airmatic suspension is notorious for leaking and going over humps quick stresses the air bladder more.

 

Plus my Lao peh car quite old I wouldn't want to stress anything on that car including the driver

Humps are used to slow vehicles down to around 15-25km/h, according to google.

Still better to be safe, go slow than to fork out money replacing parts. Haa, my 1 yr old shocks already near broken.  Contemplating whether to change as my dad doesn't approach humps gently.

Sounds like a merc S class.even if you don't drive it aggressively, its still go bad.

Haha yeah but I have to admit this model (previous s class) not so bad cost wise, we had a previous boxy model leak oil like crazy.

 

And the new model has even more gizmos in the suspension my pal dad mounted a curb and the repair bill was in the 5 digit range. Uncle nearly pengz lol

I know of s class owners who go on nshw n on return trip only one air sus bad. So car was tilted on one side. Thank goodness did not flip at highway. I disposed the traction control play a part.
