Can't get half shafts to go back in

! did everything put in it only fits half way won’t click in, any suggestions would be appreciated.

Insert the inner CV joint into the transmission while aligning the splines. Put it into place until you feel the circlip snap into place. If you can’t get circlip engagement, you can tap the cv axle shaft with a rubber mallet. Do NOT use a metal maul for this; you can damage the bearings inside the inner cv joint.

• Support the outer cv joint with wire to prevent it from dangling. That can damage the bearings in the inner CV joint and cause it to pop off and disconnect the inner boot.

Apply petroleum jelly to the splines/cir-clip.
