Default Shuddering when turn and popping while driving over bumps.

Quick summary: '06 wrx tr with 174K miles on it. I bought the car with 158K not sure what repairs were done on it before purchase. Car has been driven in midwest most of its time frame.

Issue 1: I have a shudder when turning, such as left and right turns, also a shudder when standing still and turning the steering wheel. No issues accelerating, decelerating, switching lanes, no popping, and no pull to one side. Some things that popped up in my research was wheel bearings, CV joint, control arm. Problem occuring for several months now.

Issue 2: When driving on bumps, unexpected potholes, and such I hear a sense of popping/creaking I feel like it is more towards the front but not sure according to my passengers. Tried researching but could not find a definitive answer that made sense to me and my situation. Problem occuring for a little over a month now.

I intend to make a trip back home, which is 1000+ miles away, in 2 weeks and wanted to see if I can make it back to fix my issues without a time constraint.

Thank you all for the time and patience in reading my long message!

Automatic or standard?
How is the gas mileage?

Manual 5 speed.

I have not tested the mileage recently, so I can not give an accurate answer. But I will look into it. Also if I may ask, what is the reasoning behind that?

Also I did have another issue I forgot to mention but I don't think it really affects the above problems... I have an overboost issue, but again it should not affect my other problems.

If were an automatic, it would seem like torque bind. Torque bind ruins gas mileage.

If it is similar to what I am thinking. It might be bad transmission oil or low oil. The Center diff uses the transmission oil so when turning it might not be doing the limited slip part, runs fine 50/50 driving straight, but the moment you turn its not wanting to slip.

Okay, good idea! I will look into it, then update afterwards.

Transmission oil was fine.

I solved the issues, turns out there was a stabilizer link bolt that was completely missing. The sway bar link bolt caused the popping noise when going over bumps.

The shuddering/vibrating steering wheel when turning issue was caused by a leak in my rack and pinion.

Thanks for helping, this post is done.
