Front eng thunk when going over small bumps
I did a search and couldn't find an exact match to my problem. I have a 95 525i with 69K miles. When going over small bumps in the road, like the curb in front of my driveway, it sounds like a solid thunk. Here is what I know.
I installed new Bilstein touring shocks all around.
Factory springs are installed (all suspension is factory).
I have crawled under the car and looked for loose fittings.
I have double checked all the bolts/nuts that I had off for the shocks.
I have tighted the strut housing nut (holds strut in housing).
Top nut on shock is tight.
Both wheels do it the same.
Car drives straight down the road (recent alignment).
Rear upper shock mounts were replaced with shocks.
Pushing on the front fendors the car responds as it should, smooth and responsive.
New Toyo Proxy TPT tires.
Almost seems like something isn't right with the front to back motion of the front suspension (which should be almost zero movement). The up and down is smooth.
One question: Besides getting a shimmy at 50mph (which I haven't noticed), what is the symptom of bushings wearing out?
I would like to hear your best guess on what my problem is. Thanks
I'll try the links first.
After work I will crawl back under the front end with 15mm wrenches in hand and check the swaybar links. I might go ahead and get a new set coming. Give me some time and I will send out an update. thanks for everyone's advice. Paul

Front suspension feels tight
I jerked on the sway bar links the best I could while lying next to the car. I know this isn't as good as being underneath with the car up on ramps, but they sure felt solid..... Tomorrow I will have more time and will put the car on ramps. Either way, I ordered sway bar links from BMA, great price, slow delivery estimation (next week).
I want to make clear that it doesn't feel like something is really out of wack, just on larger that normal bumps (pot holes and curb like heights) is when I feel the harder than expected noise/jolt. I might have mislead a few with my first description.
thanks again, Paul
