ok so i was going to rebuild the front axle on this yota and got to hunting around and found a new front axle for it for $100 what im not sure of is if toyota used the same gears from year to year the new axle is out of a 77 and my truck is a 85 mine had the 5 spd but now has 4 spd the new axle is out of a 77 with the 4 speed the next question is if the gears are different can i just swap the 3rd members? then i was looking at my front axle and it is so warn that the housing is shot so a swap is about the only way to go let me know what you thing thanks
