I've just finished and got my MK on the road and the poly bushes are really squeaky, whats the best way to stop them, i didn't want to just grease them in case the grease damages the bushes.....silicon grease maybe?

Silicon grease not copper grease

I say copper

Copper grease has granules of copper in it, bit like copper coloured grinding paste.
Make sure the polybush hasn't been nipped up by the mounting bracket.

Copper, or any other normal grease
Silicon is a waste of time

or silicone grease?

Just spray them with WD40 cured it in about 1 min job done

B*gger! A third option?!?

ETA - Double B*gger! Now a fourth!

Copper grease for me too. Though apparantly the copper might cause the polybush to wear down after hundreds of thousands of miles No squeeking in my car, just squeeling....

I thought Moly grease was the lube of choice for bushes?

Copper grease is an anti-seize compound, not a lubricant. Use it on the bolt shanks to prevent them rusting into the crush tube by all means.

Polyurethane can degrade with prolonged contact with petroleum based greases, which is why silicone grease is the recommended lubricant.

Personally I think polybushes are greatly over-rated, they rarely seem to last as long as manufacturers claim and very commonly suffer from lubrication/squeaking issues.
