If you think it is bottoming out than you should be able to remove the side that goes all the way and then try the other axle. If it goes all way in like this than yes it is bottoming out. If it still won't go in your splines are not lined up!
if you had read the entire thread i have taken out the other side completely with the same result. so it has to be the splines that arnt lined up. but im saying it goes into the splines fine until the last half in. is there a set of splines that are a half an inch thick thats keeping out the shaft for me to bolt it in?
in my old carrier the thrust block had some play in it this thurst block thats in the carrier has no movement in it ive tried putting a dowel rod down the axle and watching both sides with help to see if it moves.... it does not move could that be my problem?
