I have a 97 stock Cherokee sport that shakes at 60 when I hit a bump I've changed tires tierods new front and rear shocks alignment still does it I don't know what else to do anyone have any suggestions please let me know I've just rebuilt the entire engine top to bottom and it only has 126 k miles it's such a shame

Assuming it's just not small vibration from an out of balance tire,
It's called Death Wobble. All of the front end components work together like a puzzle. If you have 1 weak link the others will react to the give in that component. Personally, even without picts, I would say make sure to replace your swaybar bushings and steering stabilizer. Both are cheap and easy and can be eliminated quick.
if you add pictures of your front end, it might help. Also, look up DeathWobble on YouTube. There are a few moving-driving videos with the camera mounted under the jeep. It'll show you what you're dealing with.

No it's more like a violent side to side shake if I hit a bump at 60 or higher it feels like I'm in a paint shaker but this will continue until I slow down to 40 I have changed out all front end parts from tie rods to pitman arm

Sounds like Death Wobble, to me. Could be the tires, tire pressure, bent rim, missing wheel weight, bushings, balljoints, etc. Have you checked the trackbar mount at the axle? Have someone turn the wheels while youre underneath watching the mount. If it moves, the bolt hole is ovaled. How is the steering, in genral? Any slop?

Yes I've checked all that got a different set of stock wheels mounted and balanced new tires (I work at an auto repair shop) did the alignment my self so I know it's factory spec replaced motor mounts trans mount front and rear shocks new wheel bearings tie rod ends sway bar end links rebalanced the drive shaft new pitman arm new control arms I'm at a loss

Fb97xj1 I checked the tracking bar mount it's good and the steering is tight no slop at all

I don't know why it is not mentioned more, but since the 60's Chrysler has always been notorious for having weak frames/subframes that are way to flexible where the steering box is bolted on. I used to have this problem and could not cure it on my Dodge 1 ton even with all new parts, I stiffened the frame where the steering box is bolted and have never had the problem since, even though the steering parts are now all getting loose. The frame being too flexible right there was the actual issue the whole time.

The steering stabilizer and front swaybar have nothing to do with death wobble, you could take both of those off of a jeep that doesn't currently have death wobble and it would go down the road just fine. Since you have changed the tie rods and had an alignment already, that leaves worn, ball joints, bad trac bar bushings, bad wheel bearings, or bad control arm bushings to be the culprit.

Have someone sit in your car and you lay under the front end and watch all the steering components as the person inside shakes the wheel from side to side. Look for ant thing moving that should not be. Ball joints to include the baljoint at the frame end of the track bar look at you tie rod ends and make sure no play is seen between the ball joint housing and the steering knuckle. Also jack up your front end and use a pry bar under your tires to see if your upper and lower ball joints move. If you have death wobble there us something you will find. Good luck.

Agree with many of the above posters.

Given what has been said:
- Track bar, check the bushings and the mounts - you could easily have cracks in the frame mounting locations.
- Steering gear itself. If you have literally checked everything else and are sure all the steering/suspension components are good shape and still have DW, you could have a bad steering gear.
