99chevyblazer skips to the side

99 chevy blazer skips to the side when going over a bump. The faster you go the more it skips to the side.Could it be the shocks or tires? tires are new.It does not bounce seems to skip or shutter to the side. Thanks

Have a suspension tech do a very close inspection of tierods,etc.

Is there now or before been any wheel bearing noise?

Skipping sideways suggests to me a suspension component may be severely worn or broken.

Which one is the problem.
I would have this looked at soon, as it may well be a hazardous fault.
