I have access to a 1984 Trooper with working 4wd.
I own a 1990 Trooper with nonworking 4wd.
The teeth on the splines on front axils are stripped off to about 1 inch back.
Does anyone know if the 1984 has same splines as 1990 and is it possible to replace just the splines.
Any other info or gotchas would be helpful.

The '84 stuff won't work. Isuzu switched to heavier axles front and rear in '88. I know that the '90 trooper has a 10-bolt differential, and I think 17 splines. The '84 has has an 8-bolt front, with 20 splines on the axle. Could be wrong on the count, but I know that they are very different. Your best bet would be to just get a new set of CV's, or get a set out of a '88 to '91 trooper. '92 to '97 might work, but I am thinking that they are longer. It sounds like you had the c-clips come loose in your hubs. Are they also ground out? If so, any used hubs for '88 - '95 will work. Or you can purchase Superwinches, MileMarkers, or Warns. Post back if you need more info.
