So my front axle boots are torn to shit and need to be replaced so I'm reading that passenger side front awd axle is the same as the fwd but only 90 to 92 after 92 spline size changes but I also read that there different through all years does anyone know what's right?

I found a drivers side axle at vatozone just can't seem to find an awd passenger side if I can't find out by tomorrow rebuild it is and I really don't want to rebuild them messy messy messy

I'm 99% sure you're right. You can use a fwd passenger axle in an awd tranny only if the axle is from a 90-92 fwd. Fwd axles from 93+ are different than awd's.
