Just Purchased: '99 Pathfinder...some quick questions

[Mark_H]

Hello, 1st post. Just have a few questions regarding my new commuter/beater I just picked up. I sold a MINT '95 Pathfinder a few years ago and regret it to this day. Vehicle details and some questions below. I'm an avid "car guy" but wanted to see if I could get some feedback before I start fixing this thing up a little bit.
Thanks for any help and input.

1999 Nissan Pathfinder LE 4x4 5-Speed 220K miles

-It sounds like it's got a bad right-front bearing or hub (loud pulsing whine) that changes with speed but doesn't change much when braking or accelerating fwiw.
-Is this a common issue? Can you buy the whole hub assembly or just replace the bearings?

-The motor/transmission seems to shake and move around quite a bit, typically on deceleration and when going over semi-harsh bumps.
-Are there any known problematic motor or transmission mounts?

-This may tie into my above question in some way; but the steering/front suspension seems a little "sloppy" when going over harsh bumps...it's like the steering response just feels loose and sloppy but under normal smooth driving conditions it feels fine.
-Any common problems here? My old Pathfinder had a kind of similar issues but not identical and the death wobble that was fixed with some misc. track bars(Can't remember exactly at this moment)
