Do you have to remove the shaft from automatic transaxle in order replace outer CV boot on a 1990 Grand Am?

No, you generally do *not* need to remove the driveshaft from the automatic transaxle to replace an outer CV boot on a 1990 Pontiac Grand Am. The outer CV boot is replaceable with the CV joint still attached to the driveshaft and the driveshaft remaining in the vehicle.

However, you will need to:

* Disconnect the driveshaft from the wheel hub: This involves removing the retaining nut and clip.

* Separate the boot from the CV joint: This often requires carefully cutting the old boot away.

* Slide the new boot over the CV joint: Ensure it's properly seated.

* Clamp or secure the new boot: Use the appropriate clamps to hold the boot in place.

* Repack the CV joint with grease: This is crucial to prevent premature wear.

* Reassemble everything: Reconnect the driveshaft to the wheel hub.

While the driveshaft stays in the car, removing the axle from the transmission is generally not necessary for this repair. However, some particularly stubborn CV joints might require more force, possibly making access easier with the axle removed. But it's not a typical requirement.
