OK. News update. New brakes all the way around. Pads and rotors. New wheel bearings axle shafts. Ring carrier bearings. New lower control arms. New track bar adjusable. And still crazy vibes at 30-35 MPH. I'm having my trans rebuilt soon and gonna change the trans mount it hit. But what does anyone think? My pinion angles are good. U joints good will change them when trans is getting done. But anybody got any other suggestions on these dam vibes I'm getting

My brother just had a similar problem but not on a Jeep......
Same vibe in front end. He had recently done work to his sway bar and front end...come to find out there was air in his steering rack? Is that possible?
Not sure how he fixed it, but it was a suggestion to him that was what it could be....sure enough it fixed his problem. I'll ask him what he had to do.......I'm just guessing here.

I'm gonna guess he had a ford and that's a problem when you change a line or pump on any car. But at this point I'm willing to try anything so ill bleed my power steering.

It was a combo of my front calibers and also my bearing for the ring and pinion in the front axle. Just thought I'd update sry it took so long hope this helps anyone with the same problem. Also fyi for anyone that wants to know. I changed every suspension part except front upper control arms. Tires new. Trans mount motor mount. Brakes and all calibers.

Old fart with a wrench
Question. Were the tires bubble balanced or spin balanced? I once bought a set of tires "from a guy" cheap and found out they were factory defects that were supposed to be destroyed because they were off center! Spin them and watch the tread. They should not heave up and down. Mine did!

i put the tires on myself and high speed spin balanced. but the tires won't out of balance. the problem with my tires i put on to began with was they were used. and even tho they were all 31's they were different size just because they were all off different trucks and on a all wheel drive rig like mine it will bind up the t-case. the new tires i just bought are brand new and i mounted them and balanced them myself they are good.
