Squeaking 147, polyurethane bushes, 147 aftermarket anti-roll bars...
Like almost all others, my Alfa started to produce squeaking sounds - but already at 1,5 years and 15000 km. OK, here are bad roads, but not that bad :-( For now, it is not very loud, and it can be heard mostly when car goes over few bumps and starts to swing left-right-left....
Bad situation is that I know about this problem by reading this forum and I have already sprayed it with WD-40 few times before, but obviously it did not help and car started to squeak few weeks ago during very cold and dry weather.
When heard it, I sprayed all suspension bushes with WD-40 and this cured problem only for one week.
After this, I have tried to spray only one by one bush at a time but lack to diagnose exact bush because WD-40 does not help any more.
Car is still covered by warranty but since first squeak appeared only after 1,5 years I don't want to change wishbones now and then every 2 years or less.
Because of this, I have decided to change bushes to polyurethane ones that will be longer and more durable solution (I hope).
Therefore, I have few questions and maybe someone has the answer or good ideas:
1. if someone has PU bushes on 156-147 I want to ask how hard are they really. I can live with firmer suspension but I don't want to shake all my bones and to develop squeaks inside my car or similar...(just for info - my car is not lowered)
2. since I don't know which bush produces squeaks is there any method to find it. I tried spraying one by one bush but it did not help. Since 147 generally has squeaks on upper wishbones or anti-roll bar bushes (I am certain that anti-roll bar links are not guilty since my car has been made with new improved ones) PU bushes will not help in case of anti-roll bar because bushes on them can't be replaces with PU ones.
3. if upper wishbones are guilty is it OK to change only bushes on them or it is recommended to change also on lower wishbones
4. while all suspension is dismantled, I want to change front shocks with Bilstein shocks and eventually both anti-roll bars with bigger ones. I find front suspension too soft like lots of 147 owners but don't want to lower car. I could not find aftermarket anti-roll bars for 147 but only for 156, except from this forum - Autodelta has them, but they are from UK and it is difficult to ship them to me.
Has anybody found any other aftermarket 147 anti-roll bars?
Can 147 GTA anti-roll bars be fitted to non GTA models (147 2.0 in my case) instead of aftermarket ones because non GTA crossrail is different than GTA crossrail?
