good lubricant between rubber and metal (long lasting)

Thanks for the advice. mk4 golf forum has gone to !!!!!! in recent years. Seems to attract younger drivers now because the cost has come down quite a bit, and they're just interested in cosmetic mods.

Can imagine, some of the MK4's round here are utter wrecks!

I'm sure you'll be able to manage greasing the ARB bushes.

Jack car, support on axle stands.

Undue drop-link bolts (2 per side) 16mm IIRC.

Loosen ARB bush bolts (easier than removal), grease (1 per side) 17mm IIRC.

Re-attach droplinks.

Torque everything back up. 20Nm for ARB bushes and 15Nm + 90degree turn.

I'd reccomend Carlube Silicone grease, seems long lasting, gettiing in the tin can be a nightmare sometimes!

Because a garage "fixed" a problem they too didn't understand, it doesn't make it correct. (Jaguar garages do it too to rear bushes).
Perhaps you might like to puzzle out how the arb is effectively put into torsion with the respective wheel moving up or down, while its body location point is simply turning, causing the squeal. The arb body mount is a rubber bushing to reduce noise and vibration, but it has to be clamped tight or the arb is flopping about doing very little.
Just as well so few drivers drive close to the limit of their cars and that arbs can be safely taken off and thrown away and their owners wouldn't know the difference.

Actually, it wasn't 'a garage', it was a VW TSB. I'm going to go with the manufacturer's wishes.


And the ARB is mounted to each opposing upright, so it doesn't need to be tightly clamped or solidly mounted to the chassis rails, merely located in order to prevent if flapping around. The torsion effect is created by the movement of one wheel in relation to the other.


If the LHS wheel drops into a depression, it will set up torsion in the bar through the fact that the bar cannot detach from the RHS wheel, and that torsion will assist in 'pulling the RHS wheel down' in order to stabilise the vehicle.


I accept completely the fact that the ARB must be mounted to the chassis rails and held in place, but the OP wasn't talking about removing the bushes or letting the ARB hang loose, merely applying a little grease to prevent the bush movement causing noise. To suggest that doing so will cause any problems is a massive overreaction.


If lubricating bushes is so wrong, why would Powerflex, SuperFlex, Polybush etc supply a sachet of silicone grease to lubricate the bushes they supply?

Simple, grab a can of aerosol Waxoyl and squirt it over any offending noisy suspension bush, instant cure, won't hurt the rubber.

You need to replace your arb bushes, not lubricate them or the arb would have virtually no effect at all.

That shows a spectacular mis-understanding of how an anti-roll bar works

This should help http://en.wikipedia.org/wiki/Anti-roll_bar

Or this might be easier to understand
