Sounds like the tcase is slipping in and out of neutral. Electric or manual tcase?

Yo Christeraz,
Welcome!
As XDAILY advised; "When the transfer case is in the N (Neutral) position, the engine and transmission are disconnected from the rest of the driveline.
Therefore, the vehicle is free to roll even if the automatic transmission is in P (Park) or the manual transmission is in gear."

Identify your transmission from attached depiction.
150294

Should be AOD or C6.
AOD is used in 1989 5.0
C6 is used in 1989 5.8

See attached AOD & C6 Basic troubleshooting guides:
150296

150295



For C6, check vacuum at modulator. Modulator is on the rear of the transmission, passenger side.
Pull the vacuum line off the mod. If fluid comes out of the vacuum line your modulator is no good.
Check vacuum line to modulator from engine intake manifold source.
See attached C6 troubleshooting:
150297


Also fyi:
1356 Manual Shift, No Movement or Neutral Position Tip/Saver Spacer & pic; "...Many 1987-1995 Ford F series 4x4 trucks and full size Bronco owners with 1356 manual shift transfer cases commonly complain of a "no movement" or an occasional neutral condition. This condition is usually caused by the linkage wearing the transfer case at its point of contact (1356 manual shift models only). Sonnax offers a case saver spacer 36605-01. This case saver spacer goes between the shift selector cam and the case and requires no special tools to install. The spacer moves the cam closer to the shift fork, thus preventing and/or eliminating: 1) one or both shift forks from becoming disengaged from the shift cam, 2) "slop"from the linkage caused by a worn linkage bore in front case half. This item is a specific size/thickness not commonly found in ordinary flat washers. This repair is quick, easy and a lot less expensive than repairing or replacing the case. Model: 36605-01..."

The other thing I'm now noticing is even when I put it into four-wheel drive I have to push the buttons on the dash and normally I would hear my hubs lock and they're doing absolutely nothing at all

This is a key post.

Your transmission is working because the output shaft is spinning. This is noted because of the grinding in park. This means 100% your transfer case is at fault because it's not able to hold a brake to the output shaft nor transfer the output to the rear axle. Repair or replace your transfer case.
