I think the bushes only come fitted to the arms themselves. Maybe one of the aftermarket polyurethane bush manufacturers might do them? Try searching for Polybush or Powerflex as they supply uprated bushes for all different cars.

yea i thought about that, but trying to do this as cheap as possible as im only running the car for another year :)

edit: and you are correct, i just checked in the porter manual and you have to replace the whole arm. Perhaps doing that will stop my weird front tyre wear :chin:
 
I believe the rear bush can be twisted off, but the front bush is pressed-in. Neither is easy to remove. In my experience, neither bush is a common failure either...

The control arm is relatively cheap compared with those for other cars. The balljoint is by far the most common reason for replacement. You might like to try removing the balljoint from your old arm - some are removable - before throwing it away. It's held in with a spring ring and a tight push-fit.

Thanks,

The rear bush is the culprit for me though, the rubber has split and its rusted, and theres some play in there (more than what'd be expected).
 
Rusted rubber - of course! There's no material made by FIAT that can't be made to rust, it just takes a great deal of energy to overcome the natural stability of aluminium, plastic, rubber, etc. I remember the rust bubbles in a plastic bumper that I had once, and the rust (OK, corrosion) under the paint on an alloy wing mirror support.

Just get an arm off another, perferably new-as-possible, Uno in a wrecker's. Some people will never buy such components off scrapped cars, but I would use your judgement... many cars in wrecker's yards today are not there because of any collision, though some are, I guess. Best to avoid the ones with frontal damage?

Is this still the case - or are there now ways to replace the bushes. I am trying to trace the rattles in my front suspension and was going to try to source all the rubber bushes in the front suspension and replace them, along with the engine/gearbox mounts.

Hmmmm... four years on, I'm none the wiser - except that control arms have dropped in price a lot since then (here in NZ, at least).

Usually, the rattle/knocking is a lower balljoint, in my experience. They do fail in different ways - sometimes they have a drastic effect on the car's stability when driving on the road (self-steering effects), other times they just knock when driving on bumpy grass.

You are probably expert enough to check balljoints with a large crowbar and the weight partly taken-off the front wheels, as they do at a WOF testing station. But personally, I have had mixed results checking balljoints that way. I prefer to unbolt the base of the strut and try lifting the hub carrier relative to the arm. Quite often, the act of removing the arm will finish off an already-marginal balljoint, especially if you use a forked splitter.

I still don't think the control arm bushes are a common failure, but there's always a first time I guess. These cars are over 20 years old now... Suspension shops and even Supercheap carry a range of polyurethane bushes - something could probably be made to fit the Uno - personally, I wouldn't bother, since by the time the bushes need replacing, the control arm is likely to be rusty or bent and the balljoint may have a torn boot or be worn out. The cheapest price I've noted for a control arm in the last year or so was $75. I do remember when they were upwards of $200...

Report what you find. :)

Thanks alex, the bottom ball joints are good. No play at all, just got a wof the other day. I hate suspension rattles. so I thought I would do some reading and found this thread. I can get all the engine/gearbox and suspension bushes from a brake and clutch firm here. Some are expensive but all are poly. Control arms are $130.00
 
The Mount Shop does Uno bushes. I have actually seen a worn out one once.

Ball joints are best checked loaded with someone turning the steering wheel.

SteveNZ - in Melbourne!

Do you mean jacked up on one side to load it up and then turn the steering wheel.

Even though you have only seen one worn out, at over 200,000km they can't be new anymore.
 
No just sitting like normal. Figure out how to inspect the car underneath while someone is moving the steering wheel
