shaking in steering wheel above 70 MPH

[TeaBag]

I'm chasing an annoying shake in my steering wheel above 70MPH.

Things I have done to trouble shoot:

1. Brand new tires on all 4 wheels
2. balanced on install
3. balance checked by a different shop
4. disassembled both front hubs and inspected
5. replaced both front axle Ujoints
6. cleaned a greased front hubs with new seals
7. inspected and repacked front wheel bearings
8. new ball joints
9. replaced tie rod and drag link assembly
10. front end alignment.

none of this has eliminated the shake.

Any ideas on where I should look next?

Maybe lower steering column bearing?

I replaced mine with a cheap Crown one and had vibrations in my steering that were annoying at speed. I replaced that bearing with a ultra high quality lower steering column bearing from Wolff Engineering and it fixed it. Link below.

Caveat, I also replaced my steering shaft with a Borgeson U-Joint one to eliminate the steering shaft rag joint.

Definitely sounds like a wheel/tire issue, find a shop that has a road - force balancer basically checks runout of the tires. It's a pain sometimes chasing balance issues at higher speeds. Some tire brands are known for it, like bfg all terrains. The balancer will zero out but still have a shimmy at high speeds. Could also be a bent wheel.

Are your wheels hub centric or lug centric?

I had an issue on one of my Jeeps where I had a similar issue. Rebalancing tires had no impact.

The wheels were lug centric. So I bit some rings to make them hub centric. Issue went away.

Good resource for the bearing we need More of these so we can have decent quality parts to reference.
