Well mine just failed its MOT this week on upper wishbones AGAIN. I replaced them the weekend before last years MOT about 10k ago.
It seems these £20 eBay chinese wishbone are basically cheese, apparently the delphi arms last ages, but at 20 quid a pop its not so bad doing it once a year.

What a lotta hassle..... Get some pukka ones from alfashop and be done with it. I'd sooner spend shillings every 60k miles or so on OE stuff

I'll repeat the question. Did you replace them yourself and if so did you re-use the old long mounting bolt?

This would appear to be the common factor in a lot of cases of alleged premature wishbone failure. The bolt wears as well so re-using an old one gives you less tolerance before knocking will occur, and the more times you refit the old bolt the quicker the problem will re-occur the next time.

I replaced upper 'bones' circa 60k for OE spec parts and new bolts. Price of parts seemed to be very reasonable all things considered. Simple common sense to replace bolts for new and apply a good dose of waxoyl for a bit of protection.

Silicone grease seems to be the preferred option. I'd be wary of using Waxoyl near bushings as it is thinned with white spirit and that stuff isn't too kind to rubber.

Only ever had to replace one set of upper wishbones in three 156's I've owned.... That's in about 95,000 miles total between the three...
Secret: There isn't one!
Just common sense and a little bit of knowledge I learned in my apprenticeship

I'll keep it short:
Use a hyperdermic syringe filled with silicon lubricant.
Push the needle in as far as you can & inject into the outer edges of the bushes as soon as they start creaking (listen to your Alfa, more often than not, it will tell you what is going wrong).... Not six month later when you can be bothered! It's far too late by then as the damage is done...
Rubber vs alloy, what's going to win a friction contest?
The idea is to lubricate the bush so it doesn't get the chance to shrink (which causes the friction), crack and then perish... Job done and it isn't difficult.... Total cost £ 5.00 and you can use the silicon lube on many other items and parts etc.

How it works: it feeds the rubber and swells it back up to original size, as Del boy says "a little dab will do ya"
Or you can replace the upper arms every 24,000 miles, your choice at £££'s a time

I know what I prefer to pay!

I do this every six month and you can also do the anti-roll bar bushes the same way while you are on!
Prevention is far better than the cure..... Isn't it?

All three 156's have had the same treatment, all three have passed multiple MOT's with no issues from the bushes or arms and they don't ever squeak!

As far as siezed ball joints: The same method can be used into the rubber boots with some plusgas injected in, let it do its job then simply reverse the process using the vaccuum of an empty syringe to suck it all back out.
Then re-inject using the correct grease, give it a good wiggle on full range of motion. Mark the hole you made with some chalk.
Then rub some vulacanising fluid from a bicycle puncture repair kit to seal the pin hole you made.

I'll let you guys decide whats best on your own alfa's

Good call on the new bolts and the syringe idea.
I'm assuming though the bolt is not supposed to rotate in the housing, because the metal bits of the bush rotate inside the rubber on mine? If that is correct then as long as the bolt is tight enough there should be no play as it does not move. Obviously it is wise to replace it anyhow.

That's one of the reasons I swapped to a vRS, at the £2k end of the market was sick of changing them.

A 156/147/GT owners definitely need some long term solution for suspension squeaking .... with your experience we are on a good way to find it

Are you sure it's not an engine mount aswell?

You weren't paying attention, were you....?!

Using silicone grease to lubricate suspension bushes is not a miracle discovery. It is commonplace. It is just that with today's 'replace rather than repair and maintain' mentality people assume that swapping in new parts is always the answer and are surprised when they hear that it isn't.

Also worn & past-their-best shocks help kill upper arms faster.

Quite correct. The bolt should play no part in any looseness because it is torqued high enough to lock the inner metal sleeve to the housing. The rubber bush rotates around the inner metal sleeve, which is where the wear occurs. Frankly dismal bit of design that would have been better off left on the medieval cart it came from !

I don't think any medieval carts had fully independent double wishbone suspension...

Simple...
Before mounting the upper arms take some time to remove the rubber bushes from the arm (easy enough to do) remove washer/inner tube from bush.
Assemble everything back together with a nice amount of grease and only then put it on the car.
No noise/squeak and they last much longer
Remmember that after the correct torque the washer/inner tube makes a solid unit with the arm support.
