I have an issue that's beginning to get annoying sometimes when breaking I get a clunking sound coming from both the passenger and drivers front wheels I also sometimes get a loud sprung clunk but this isn't as common originally thought it was the wishbones so had them polybushed which appeared to resolve the issue temporarily but it has now returned, its not constant as in every time I brake but happens regularly enough that I want to solve the issue any one have any ideas before I take it to a mechanic.

I'm thinking drop links or maybe shocks but when my friend did the wishbones he said he couldn't see anything wrong with either of them, the clunking originally started after I fitted new brake pads which I got my frirend to check over once the noise started to make sure I hadn't done that wrong even though I've fitted brake pads before with no issues, he didn't see any problems but did spot that the wish bone bushes were on their way out so I had them polybushed.

So does anyone have any Ideas before I take it in, if it is the shocks I'm eyeing up the PFS set with lowering springs on parts for volvo has anyone had these fitted and can provide any feed back.
