What is causing my front end to ride rougher than it use to?

Just because the struts have no leaks doesn't mean they are not worn out, the fronts last about 50-70,000 miles (average road) depending on road conditions, the rougher the road conditions the faster they wear out.

strut buffer located under hood

check front-end out, immediately, could be a bad bushing/ control arm, this would need attention, asap, you could lose control of vehicle, or somethingelse is broken, shock, but the control arm / bushing is my bet. get it repaired, unsafe condition !!!

Certainly it could be shocks - worn shock absorber valves can cause some horrendous noises on certain types of road service, though strictly the noise could be caused by anything and there is no point guessing - only a hands-on inspection will reveal the culprit.

check upper and lower balljoints both sides

sounds like sway bar bushings

Check your steering stability bar I had the same problem and it turned out that I had bent that bar.

The death wobble is basically when you are driving your lifted jeep down the road and the front end starts to shake violently. It can happen at virtually any speed, though mostly above 40 mph or so, and is a frightening experience, especially for those witnessing it for the first time. Now it doesn’t throw you off the road or anything … the front end just shakes. And the only way to stop it is to slow down and pull over. So it wasn’t that hard to get used to at first. But as it happened more and more, it seemed to get more and more out of control.

Hope help (remember comment and rated this).

bal joints and tie rod ends

You should perform a test of the struts/shocks or have them checked to see if they are leakiing or just worn out. The biggest factor in your ride would be that.

Additionally, make sure you air pressure in the tires isn't too high. Generally somewhere around 30 pounds cold is a more comfortable ride than at 32 pounds cold. More air pressure saves fuel but can make for a rougher ride.

Good Luck

correct size tires? correct pressure? aftermarket shocks ususally ride rougher than OEM. all bushings OK?
