I'm installing tapered roller bearings on my 1959 apache 1/2 ton front end and since the truck is on stands, I noticed that the steering is stiff/tight when I start to steer to the left or right of center. Once I turn the wheel a few degrees past the left or right of center, the steering is smooth like it should be.

Before I dig into pulling all the steering apart, I'm wondering if anyone has any idea of where I should first look into this issue.

All lubrication points have grease.

Thanks in advance.
