I drive down the road at 25-40 mph and the steering wheel wobbles like the
dipsy doodle for the old timers here. I have replaced the Idler arm, all
tie-rod ends, checked the wheel bearings for wear, replaced all four shocks
as they were totally depleted. It got a little better after changing them
and now it has gotten even worse than before. I have new tires on the
truck. I took it to the dealer they put 4 new tires and rims on the truck
from another truck for testing purposes and it improved it a little but it
still was there. It is gradually getting worse.
What else is there that could cause this, the steering gearbox?
