Lucky they are riveted in, I may have to do a 87 Nissan Sentra 's which is pressed in and held in with a snap ring. Some " know- it- all " kid thinks he can do it no problem.
Hope he did his research cause I did, if you pull out both the axle shafts, you need two $90 a piece tools to align the ends with the ring and pinion inside the trans to put the shafts back in, plus all your fluid leaks out.
There is a way to cheat but I aint telling him.

A-arm has to come out anyway, but a new one is $89 with new bushings and ball joint. Its $9 just for the ball joint plus you have to find someone with a press.
