My husband's Subaru B9 Tribec has a horrible shake in the steering wheel a When he is at around 70mph or if he is at highway speed and there is a bend in the road. It happens almost all of the time. He has done the following to rectify the issue...
1. New Wheels
2. New Tires (balanced, aligned, everything)
3. New Tie Rods.
Do you have any suggestions?

Erica,
You may have a wheel bearing concern, I suggest you have a trusted professional verify.
Hi Erica,
If he did the work himself, I would suggest taking it to a shop for a diagnosis.
If he had a shop do the work, I would bring it back and have a technician go for a ride with you or your husband so he can experience the same horrible shake.
If they can't find anything wrong, have them check to see if the tires are defective. This is rare, but I have seen it happen.
If this issue began immediately following the new wheels & tires, I would think the tires are not balanced properly. I'd bring it back to the shop who did the work and have them advise.
What kind of tires are on this vehicle? If they are more of an off-road tire, it is going to have a bad vibration at highway speeds.
I would start with finding a shop that has a road force balancer. This machine applies pressure to the tire as it is spinning. If there is an issue with the tire or the rim, this will find it. This is not the same machine used to routinely balance tires in most shops. It may take some research to find a shop that has one.
Have the front end checked as well. Worn bushings can also have that affect.
