Polyurethane bushes and squeaky noise
Discussion
Hello!
it's my first topic here, might well be in the wrong section
I have had Powerflex front lower wishbone bushes fitted on my Clio 172 for a little more than one year and I'm overall happy, but I have a problem that I cannot solve, so I seek for some advice.
When I fitted them, as per instructions -probably the only ones I read in my whole life- I greased the surface between the bushes and the sleeves with the copper grease provided.
Everything has been perfect for 3/4 months, then a squeaking noise started to appear whenever the front suspension were loaded. I then took everything down again, re-greased the bushes and it went quiet again, you guessed it... for another 4 months or so.
Now I have put again grease between bushes and sleeves and it's back quiet...
I keep using copper grease as supplied by Powerflex.
Does anyone have similar problems with these? Shall I take into account that I have to redo the job twice a year?
I mean it's not really a problem, it's an easy task, but if you have other suggestions I'd be more than happy to try them out (apart from welding the wishbones to the chassis of course, I can't weld )
Any idea is really welcome!

Or keep them, safe in the knowledge that it's masking the noise of the various other squeaks and rattles you can do nothing about?
Thanks for the feedback. I'm keeping the car only as a trackday toy after 13 years of loyal services as a daily commute, so I really don't mind doing a regrease job every now and then if it's required. Simoid, remember: as long as something's squeaking and rattling means that is still there... worrying thing is when it suddenly stops

Copper grease is not the right grease to lubricate polyurethane. A teflon based grease with a HP element would be correct or a high quality synthetic marine grease.
Intersting, as Powerflex provides copper grease which actually in my experience gets quite sticky over time, so probably using a teflon based lubricant as you suggest will be a better option. I will do that when time comes
I start thinking that either google doesn't work for me or it's so logical that Poly bushes are noisy that Google list this search as to-bloody-obvious-to-be-real
