Nissan Forum - Nissan Enthusiast Forums - Frontend and steering wheel slop

I have a 1993 Altima that has a front end /steering issue. WhenI hit a bump or a dip the steering wheel goes crazy, bunch of slop in steering wheel, goes left and right TO easy immediately after the bump or dip. Then it seems to get the resistance back after a few seconds.
I was thinking the rack-n-pinion but I’m not sure that would be correct. I haven’t gone under the car yet to look but I wanted to get an ideas to if there was something specific I should look at while under the vehicle.
