This type of pad movement within the calliper is quite normal and providing all the pins and clips are in place then it is nothing to worry about.

This will fix your problem as long as the squeak is from the ARB links mate.
Very easy to fit and adjust.
The only issue that you may have is getting the old ones off but if you are handy with the spanners then there should be no drama.

I doubt if it is oil, I certanly hope it is not.
Is your car using oil or have you perhaps overfilled it ?????
Are you sure that it is not just water/condensation emmissions mixing with the exhaust emmissions.
Here you go mate, all in stock, same/next day shipping.
Drop me a pm if I can help you further.
