Technical multipla poly anti roll bar bush upgrade

[nelsonrocha]

think I'm going to stick with the saab ones. The Rover 100 ones, although well sized, have the hole for arb higher up than the Multipla one, so could affect something...

I think the best is to buy the original ones:

Send a message to the site owner with your FiatForum username and he can sell you the bushes for 38€ with postage included.

I would hardly think so as it is the original bushes that are causing the problem. With the Poly bushes there is the advantage of better handling and they are cheaper!

Don't knock it until you try them. Terrible pun!

sweet 45 euros for a pair of fiat marea bushes that wear out in no time
it even says on the website "rubber" and "same as the manufacturers" :bang:
that is why we have swopped to poly arb bushes they are vastly superior to the old rubber ones.
plus about half the price delivered than the weaker bushes
no contest in my eyes
peace

I have an Alfa Romeo with poly bushes too, and I also know that with the better handling comes the greater vibration. You need to make the choice beetween better handling or confort.

They sell them for 38€ and not 45€ (for FiatForum menbers), and yes they are weaker than poly bushes but they don't transmit vibration through the chassi.
And don't forget that you still need to cut the poly bushes to fit.

 

[klytus]

granted they are easier to fit
but the vibration through the arb your talking about is non existent m8
this is our 2nd multi and both suffered with terrible knocking, the arb bushes that i took off were still a snug fit on the arb, the problem was the bush and bar move in the arb bracket you cant simulate it without a long metal bar and the mot tester will almost never pick it up as the bush looks fine when on ramps even when they test the wheel bearing play its not noticeable at all.
when you fit the original or silentblock bushes the bracket does not grip the bush with any conviction thats why they wear out quickly.
the only time i have known vibration through the chassis via the arb is when you hear that awful knocking telling you its new arb bush time and that is because the std bushes are not upto the job, the car has a much higher ride hight and centre of gravity than the marea is also as heavy and has twice the body roll as the marea but fiat fitted a car arb bush
this multi we have is a completely different drive now its got a heavier duty bush dampning the arb
its entirely up to the person fitting them wether they follow my guide and fit std arb bushes or fit heavy duty ones each will do the job fine, the poly ones will never need replacing for the life of the car, that alone is worth the extra 15 mins getting the poly's to fit.

...would love to see pics of the bush/bracket making process ...

Will do. I've made one bush, and started on the clamp/bracket for it.
It'll be a while, it's way down my list priority-wise I'm afraid
I'll post a pic later (I'm at work, and Photobucket is blocked...spoil-sports)

...its just a shame the end of the arb where it bolts to the droplink has been flattened and drilled or they would just slip over the bar and you could make them without the cut in them
peace

As I'm sleeving the bar where the bushes go, the hole in the bush will be larger.
Also, I'm going to grind down the ends of the bar slightly if there's enough 'meat' to do it safely, then the bushes should hopefully slip over.
Does the poly' get more elastic when heated, e.g. put in boiling water for a while?
If I can't get them over, I'll just slit them, it shouldn't matter really as long as the slit is located horizontally to front or back.

 

[BikeDoc]

Bush and clamp section (tube will be split in half and welded to brackets made from rectangular box-section)
The basic idea, I'll probably have to alter it a little once I've got it all off and measured it up but you get the idea hopefully...

yes m8 the warmer they get the more pliable they become, i noticed this when the linisher i used heated up the poly it became a bit softer,
put them in an old kettle and boil some water up they should be a lot easier to fit over the arb end
those bushes look sweet by the way, loads better design and will last a lifetime

That's the plan!

Why don't cars have ARBs on the rear as well?

my saab cabrio has a rear arb not sure why it don't on a multi
would be real easy to fit one to a multi .
its just finding a bar the right width but should not be a problem

[pondweed]

got BOTH the sets of poly bushes now.

The Rover 100 ones look very good and 'possible'. But what would happen if the arb is held a couple of mm higher in the clamp? i.e. the hole is slightly higher up the bush.
If one has to shave off below, then they might not be tall enough. If not, they could be an easy option.

Cost cutting I guess?
I've seen them on trucks and some of the larger SUVs I think, maybe they're not deemed neccessary on lighter vehicles, although with six adults plus luggage you couldn't exactly call the Multipla light

...what would happen if the arb is held a couple of mm higher in the clamp? i.e. the hole is slightly higher up the bush...

A couple of mm won't upset it, and it won't foul on anything.

 

[pondweed]

well, in that case I may have some pre-checked poly bushes available soon as i've started amending the larger ones to fit, as others have already done.

But if the geometry wont be affected (it seems a better idea to have more rubber around the thing tbqh) then the Rover ones should be the way to go as long as they are a snug fit in practice. Cheaper too.

I'd call the above an ARB. What would you call it?

[klytus]

is that on all multipla's
i never noticed it on ours, but have not done any work to the back end

Same as Fiat, a

TORSION BAR

?

Only had mine since 3rd Oct and haven't had a crawl under the back...yet
Still too busy trying to find the fault with my heater/air-con circuit :bang:

Pity the front one couldn't be bushless as well eh?

 

[klytus]

Still too busy trying to find the fault with my heater/air-con circuit :bang:

did u remove the 5 wire plastic plug in the footwell and replace it with a 5 segment scotchblok or a better connector ?

our dash, heater and all sorts were flashing like crazy till i removed the plug and cleaned up the wires and joined them up
if u want i can take a pic of the repair i did on ours but it will need to be in the daytime
i put it down to fiat electrics but that plug is a poor connection and needs a better solution as it draws a fair bit of current , part of my plug was partly melted
peace

 

[BikeDoc]

No, I haven't had a chance to look at that connector again, will do soon though.
