Need help Diagnosing Steering play - Steering rack & Front control arms

ZPWR

Yo fellow Z enthusiasts. I've got another issue with my steering on my 370z where on the straight roads with slight bumps causes the steering wheel to jerk left and right and becomes pronounced under braking to a stop especially on
the same bumpy roads (no potholes just rough road surfaces). It's almost as if the sensitivity of the steering wheel has just increased over time. Most possibly due to my weekend spirited driving up in the mountains haha! This car is too damn fun in the windy mountain roads. I try my best to avoid heavy road surfaces and potholes like 99% of the time.

Also my knowledge on suspension systems is very limited and I've only got about a little over a year's worth of mechanical experience as an apprentice mechanic so any helpful info, tips and advice is very welcome.

Anyway down to the point - My steering rack boots was sweating down to a near drip leak last year. I opened up the boots a little bit to see what the inner rack looked like and found something interesting. One side was filled with lots of grease while the other had very little if not any. I recently cleaned it and rechecked a few weeks later and is dry as a bone externally on the boots.

Also my front lower control arm bushes look like they're starting to leak out or already have. One side had more black liquid marks than the other. Not sure if this is contributing to the problem. I didn't get a chance to check the condition of the upper control arm but I will next time I jack up the car.

What are the long term symptoms and possible damage could I expect If I don't rectify this issue in the near short term?

I've read up into these 2 articles:
Front lower contol arm bushings blown?
The Complete SPL Front Suspension (Thanks for the great post rusty!)

So yea any helpful input or additional information I'll gladly absorb and learn from you all. Many Thanks!

(Sorry for the long wordy post. I felt I needed to give as much info as possible to narrow down the issue)
