I notice annoying creaking noises from the rear suspension in the KL when going over speed humps. Is this a known issue and is there a fix? Might be worse when cold.

KH does it worse, but its got over 200,000 k's and i put it down to wear. I don't recall the KH doing it at 60,000 k's which is where the KL is now, so i'm assuming some rubber parts may be degrading with age?

If it's just over speed bumps it may be the swaybar bushes need lubricating

Thanks !
