Shaky steering

[Mreynoldsrn]

Needing some guidance- I have a 2017 JKU. A few years back we upgraded the tires from 35” to 37” (used) and noted that it gets shaky between 58-63 mph. It’s noticeable from other drivers After months of driving like that, we upgraded the steering stabilizer, tie rod, drag link, and replaced the ball joints. It seemed to get a tad better but didn’t go away. About a month ago, we finally got new tires, 37” and for a few days seemed completely healed. However it started back up again. I haven’t gotten the “death wobble” yet but it does make me nervous having experienced that in the past.
Looking for suggestions as to what we are missing. My husband is ready to set it to fire! thanks

How much tire pressure do you have in them?

Do the chalk test to see where they should be set at, lots of info on the Web about the chalk test.

Tire pressure is about 33-36 psi

I’ll look up the chalk test

Your ideal tire pressure is going to be closer to 26-28 psi, I can almost guarantee it.

I would take the wheels in and have them balanced. There's a good chance a weight fell off of them.
