04' Sierra Steering Issues
 

Ok. so my dad paid off his truck last year and was about to trade it in. I talked him into keeping it as it's a really nice truck. Since then he has spent near $5000 on repairs! Rear main oil seal, 4x4 switches and actuator, inner tie rod, and several other things I can't remember.
Now it's in the shop for a leaking oil pan seal...apparently you have to pull the engine for that?

He has noticed the steering has some "roughness" when you turn the wheel to the left slightly. The gear box was replaced under a recall along time ago. Truck has 120k miles 4x4 extended cab. I also noticed the centerlink is loose from the pitman arms, but can't tell if that's normal. When the shop replaced the inner tie rod they didn't mention the center link or bushings, but I got underneath the truck while he turned the wheel and there is some play where the idler arms go into the centerlink.
Anybody know about some slight "shuddering" in steering? It's not very bad at all, but didn't used to do it. Only does it when you turn the wheel and normally when you're moving forward.
