I am in the process of installing the gforce axles and need some guidance. I started on the passenger side loosely following the writeup posted on a thread. I have the stock axle disconnected from the diff side and sitting below it. I also have the hub/knuckle disconnected from everything expect the upper a-arm ball joint. The issue is I can't seem to get the axle free from the hub. I have tried to hit it with a rubber mallet and dead blow hammer. I have tried using axle pullers from autozone/advanced auto and the flange is too short so I can't get it locked down on the studs or get the thread started in the middle. They have one with an extended flange but the studs get in the way of getting that in place as well. How are people getting the axle freed up from the hub and out of the car? I have read several posts were pisnuoff says don't disconnect the upper a-arm to pull the axle from the diff which I agree no problem there, but can't seem to free it up from the hub itself. I do have the axle nut off but unable to push it through. I also tried the 3 bolts holding the hub to the knuckle but the axle joint is preventing fully removing those as well.
Did you disconnect the A-arm ball joint then to pull the whole thing out? I understand the concept of using the axle weight inside of a metal bar but I can't get it away from the car.
The problem is I can't seem to get that upper a-arm ball joint loose nor can I get the hub bolts loose, nor can I hammer the axle through so it all sitting together on the car. Any suggestions welcomed, I even tried an small air hammer on the axle itself based on a G8 owner thread but no luck with that either.
So let me see if I have this right, you removed the nut from the upper a-arm then hit the upper a-arm bolt with a dead blow hammer from underneath to disconnect it? After that was done you pulled the entire rear knuckle with axle attached off the car. While off the car then you loosed the 3 hub bolts using an impact? Does that all sound right. Sorry been fighting this since Sunday and can't get my upper a-arm bolt to budge at all.
Are the u-joints perhaps larger on the 06-07 V, I don't see how the hub bolts can be removed with the axle attached on the car as the bolts quickly run into the u-joint when backing them out. There is also no way to get a socket on the lower again due to the space taken up by the u-joint.
I put the whole thing back together tried a pry the a-arm ball joint again no luck just won't budge. Thinking I should just take it to the pros on this one since I can't free the axle or the knuckle to get the thing off the car.
Found this trick posted on another forum and it helped big time.
"What I did (and ewill3rd does) was use a 1/2" extension for a socket wrench BACKWARDS (so the opening was facing the threads/nut. I loosened (not removed yet) the nut and then put the extension on the nut and hit the ext. with a hammer. One good crack and the Ball Joint popped loose."
I took a 1/2inch impact extension and 4 pound hammer and finally popped that thing. Now the fun begins as I have the axle and knuckle still attached but out of the car.
branland thanks for responding have a few more questions if you don't mind.
Sounds like then you took the axle with knuckle off the car then? If so how did you separate the outer cv joint and knuckle or did you just leave that together, or did you remove the knuckle while the axle was still connected to the diff? Trying to figure out the best way to move forward from here and if I really need to disconnect the knuckle or just leave it on the outer cv joint and focus on getting the axle replaced within the cv joints at this point.
I tried different hammers and even dropping the entire thing 4 foot on itself hub side down with a socket fixed to the axle nut taking the impact hoping to push the axle spline through the hub. It just wouldn't bust for whatever reason. I was not able to fully support the entire axle hub side up in my garage to really pound straight down on it which was a suggestion.
I had a very similar experience and ended up taking the whole assembly to a garage to get it apart. Soaked in PB blaster overnight, airhammer attacks, soaked overnight AGAIN, more airhammer time and it finally let go. Make sure you put a little antiseize on the splines when you put her back in. Good luck, I definitely feel your pain on this one.
