I own an 86 GT. Recently I had my tie rods and a lower ball joint replaced, yet I still have a groaning/creaking noise when I turn. I've only noticed it on left turns, but they're the only turns I have to make super sharp. What would the most likely causes be?

When you turn "at lock" or "sharp" the front spinal hit stops somewhere on the suspension and often makes noise.
Clean and Lube the contact points w/ a thin film of Brake Grease.

Front and Rear Wheel Bearing are Not preloaded and allows some minor play... If the brake's "dirt shields" are bend can hit the rotor and make noise.
Look for "wear" where the shields hit.
If the rotor as been replace, some are not made right and hat areas does same... Likely need to pull the rotor to see "wear marks" on them and shields.

I just had my bearings redone and well, but my brakes, rotor, caliper, and pads, are basically non-existent. I'll look at the shield there. Thank you!
