Clunk when slowing down Sign In

2003 Mercury Sable LS DOHC 170,000

This is my girlfriend's car....I was driving with her the other day and when she hit the brakes I could feel a clunk in the passenger floor board (front). It's more prominent when slowing down a slower speeds, but it has also occurred when hitting a decent size bump. She claims she's heard a pop if she turns her wheel all the way in one direction as well, but I haven't. I really don't even know where to begin with this thing....any input would be greatly appreciated.

Certainly has to be found and fixed. Brakes, struts and control arm bushings all involved with holding wheels in position with assorted forces to be checked.

Might be hard to find without some help. Jounce car just sitting there. Hoisted in assorted ways to pry and inspect what can move that shouldn't with vehicle weight and hoisted. Hard to do alone unless something wildly obvious but you can't let it stay that way as it clearly suggests a safety issue at hand,

I forgot to mention, it's one single clunk, not multiple when it occurs.

Could be ball joints, control arms, tie rods etc. It needs to be inspected by a suspension specialist.

Maybe a torn motor mount also.

OK. Just another option because noises can come from anywhere.
