Last few days, just noticed it over bumps/pot-holes...

Pretty confident it'll be the upper wishbones as I think they're still the originals from the factory, but I'm gonna take it into AutoLusso Bornemouth in a few weeks time for some other work so hopefully they can confirm it!

For the moment I'll give the bushes a liberal soaking with Silicone spray/grease to get some more out of them, but replacing uppers looks simple enough to do at home.

So my real question - is it worth Powerflexing these bushes when I get round to replacing the arms?

As I understand it, it's the bushes that wear/fail rather than the wishbones themselves... Would Powerflexing these up cure the problem?

Yes. Loz did mine and I've NO squeaks or knocks at all. Yes I do have a 156 - talking about the JTD.

How long ago was that then?

I know some people keep up regular greasing of the bushes and get extended life that way.. Just wondering where the balance is between regular greasing and powerflex...

I replace mine with original OEM TRW items. I've replaced them twice in 8 years...BUT....the car did spend several years covering barely any mileage and standing still does no favours to the bushes. It's worth noting that whilst you may need new upper arms if they have never been replaced, that the antiroll bar drop links make a very similar creaking noise to the upper arms when they are worn.
Oh and the job is very doable on the driveway if you have a decent set of axle stands and are vaguely handy with a spanner.

Yea I was gonna get OEM replacements from AutoLusso's online shop.. Heard plenty of people having trouble with the cheaper third party replacements...

Droplinks an easy job too eh? Cheap enough so might as well do them too whilst the nose is up in the air... Managed the rear pads, slave cylinder replacements, and clutch release arm lube-job without too much trouble... It's all nuts and bolts right ;)

If your happy doing these jobs on your car then you'll have no trouble with the suspension. Buy a half decent scissor style ball joint splitter and you'll be fine :)

Probably worthwhile doing if you are replacing them. But to be honest its a gamble because the uppers are not that expensive and as long as you grease them up the uppers will be fine.

I imagine the ball joint will go before a powerflexed bush.

I have a few powerflex bushes from engine mounts. But the uppers and lowers i never bothered with it.

Well that's my suspicion confirmed!

Took it for a quick run out to the shops this evening after lubing the upper arm bushes right up today... Not a peep from them over the speed bumps!

Will add "lubing bushes" to my fortnightly wash.. Can't lube them too much ;-)

Glad you got sorted , read a lot on hee about this as I have the same problem only the steering is adding to this.This has happened since I renewed the iupper arm after getting the usual knocking due to wear, the knock has gone but terrible creak and squeak. I have greased everything with silicone spray but for nothing . I have figured that the top mount is th culprit , something has happened on the rebuild and needs to be slackened and retightened , not too much mind !
Anyone had this problem after rebuild?

Had exactly this problem recently after travelling over a ridiculous number of speedbumps. Very loud creaking and squeaking started after I resumed my journey It was realy so loud I thought something seroius had failed in the suspension. It also creaked very badly with just a little stering applied -I was beginning to think it might be steering rack related. Eventually traced it to the top mount on the drivers side. Hit a large bump before I got around to replacing it and the noise stopped. That was 3 weeks ago and still silent. I've had Alfas before so I know that this is just a temporary reprieve and I need to buy a top mount! In my case it was not related to upper arm replacement but I can imagine how it might be possible especially if the top mount was worn.

Did the sqealing happen on suspension travel as well as turning.Iam just trying to see if your problem was limited to steering only.

I have this...

Creaking when turning the wheel, breaking and slightly uneven roads. Although sometimes it disappears completely.

I have replaced upper wishbone, so now suspect lower wishbone or ARB bushes....

Think lower wishbone and ARB bushes are more a challenge, so may bite the bullet and drop the car off at AlfaAid in Maidenhead. MOT due in 6 weeks, but not sure if its an MOT fail or not?

Think the ARB bush isn't. But the lower wishbone will be if deteriorated.

I think...

Editor - how do you lube the bushes - how do you get the lube in there.

I take it the x2 bushes are where the upper wishbone attaches to the car body

Lifted the front via the jacking points enough to get easy access to the upper arm bushes where they join the upper mount, sprayed the **** out of them with WD40 Specialist Silicone spray.. Left that to penetrate/soak in for a few hours before driving...

Not as good as stripping down and applying grease right in there, but one helluva lot easier!

Both. It was really bad. Just can't emphasise how loud it was. Creaked badly over bumps. When turning steering (even only a very small amount) it squealed and creaked. Maybe yours will cure itself like mine did:lol:

Hi

Quick question, when you spray the suspension with silicone do you have to take the wheels off to get access or just jack up the car a bit?

My 156 has started squeaking over the speedbumps so want to get it sorted.
Cheers!

I left the wheels on because I'm lazy!

With the front lifted the suspension drops, leaving enough room to in above the wheel and exposing the bushes... Also makes it a much quicker job: Jack, spray, let-down.. 10 mins max for both sides...

Not as thorough a job as you could do though.. I did read a method where you pop the wheel off and use a syringe/hypodermic to inject the silicone oil directly into the bush along the central shaft.. More effective lubrication for sure, but a lot more effort..
