My understanding is that the front beam axles were the same from 1984-2001, the difference being the steering knuckles/brakes changed about ''91. The old-style spindle knuckles are no longer made, but the newer style will fit the early axle. This is in reference to 2 wd only, not trying to cross over to 4wd. In a nutshell, any year axle would work, but have to change the knuckles, brakes? Any help appreciated.
