I recently changed all the drivetrain fluids, but now when I turn, mostly noticeable at slower speeds, it doesn't feel smooth like before. There is a "clunkiness" to it is the best I can describe it. Did I goof something up?

Fluids:
  • Front differential - 2.6 liters GL-5 (Amsoil)
  • Rear differential - 2.6 liters GL-5 (Amsoil)
  • Transmission - 4.2 liters GL-4 (Amsoil)
  • Transfer case - 2.6 liters GL-4 (Amsoil)
I got these oil types based on what I saw others do here, but there is also this for reference which contradicted what I saw here.

1995 HZJ73, Manual locking front hubs, 105,000km

Thanks in advance!

Hi
Oil specs appear to be correct.
Check your rear axle: If it is a limited slip differential (LSD), you need special 'LS' oil or respective additive.
Axle Code last digit 3 or 5 indicates LSD.
The amounts are only rough figures.
You put the vehicle on a horizontal ground and fill up until it starts running out of the filling plug.
On a hoist, the vehicle is not sitting level, commonly resulting in overfilling.
Note this common mistake.

If the above mentioned is all OK, try to better identify which gearbox or diff is clunky.
Did you check the magnetic drain plugs for debris? Maybe strain the old oil for debris.
Good Luck Ralf
