Front and rear end rebuild wore out factory parts

[marktjbrown93]

My jeep has death wobble and a vibration at anything over 55 I need tires and at the very least ball joints anyone have a list of parts to rebuild the front end and rear end bearings and everything I'm on a bit of a budget. please help me with any ideas on what the vibration might be.

Before you throw money - and then find out you missed it - focus on learning how to diagnose things-

also not sure your mechanical background , so work safe -

1. Lift the front wheels and check for unit bearing slop by rocking the tire

2. Learn about the dry steering test

3. See if the tires will balance if not replacing any soon

4. Alternately pull the driveshafts and run the vehicle.

5. Ball joints can be checked with a pry bar and the wheel lifted

there are more ways to test things , and more things to test

Anything that spins can cause a vibe-

A lot of owners replace near everything in hopes of nailing it, learn nothing and still are at a loss- I did a lot of that.

Use the search engine here and read read read.

On the street everyone has ideas, mostly guesses. Work to understand the entire axle and steering system and you’ll do a lot better now and later.

Patience and persistence is key.

Edit, I typed this before I saw Andy’s response, similar.
If it’s really DW, I encourage you to first diagnose the DW to find the problem-throwing parts at it is expensive and a lot of work. Often, DW is triggered by a bad tire (bulge, out of round, etc), starting the vibration which escalates into the scary oscillation. Many threads and experts on the forum recommend a static inspection such as the following:
—get under the front end with the surroundings as quiet as possible (so you can hear)
—have a helper get in the Jeep with windows down, the steering centered and the engine off (again quiet)
—the helper turns the wheel slowly right a bit (1/4 turn) while you listen, with one hand (yours) lightly on the steering linkage and the other hand (yours) lightly on the track bar.
—the helper then turns opposite direction to the left ~1/2 turn past center to about 1/4 turn left.
You are feeling, listening, and looking for a pop as the steering direction changes. The helper repeats this back and forth until you can isolate to the loose component. Possibilities include:
-Track bar end bushing to pass side axle top mount (check bolt torque anyway)
-Track bar joint to driver side frame mount
-steering link tie rod end to passenger side spindle
-Steering link tie rod to pitman arm
-Tie rod ends on long tie rod from steering link to drivers side spindle (keeps drivers front wheel turning with pass side, holds toe in)
-control arm bushing
-ball joint
-Wheel bearing

I hope this helps. Try it and let us know.

Before you do anything, get those new tires and WATCH them and MAKE them balance them to 100% balance. That is the single biggest source of front end issues.

My video here covers all the others.

Thank you all for the help I know it needs upper ball joints. I replaced the front hub assemblies and that's when death wobble started. I've got other issues that are hard to explain no clue on those almost like the big tire wawawas lol but more of a metal feeling. I'll start checking all of the other things you all mentioned and let you know what I find after I replace the ball joints and get a alignment. What pictures do I need to put on here

Unbalanced tires can trigger death wobble, but I wouldn't call them the "cause" of death wobble. The cause is loose/worn front end parts. Like some of the above posters mentioned the best thing you can do is get under the Jeep with a long pry bar and start looking for play in suspension and steering parts. The trackbar and steering linkages are prime suspects.
