Ok I had an oops over the weekend! I was putting my wheel spacers back on and I stripped the bolts on my drivers side wheel hub! I have already orderd the part but I have to clue how to change one out?? Can anyone help me on this one?

You mean the wheel mounting studs? If there is room on the back side to push them out, you use a stud remover which is like one of these:

Then insert the new stud and using the NEW(can't use the old ones) lug and some washers, pull it in until the head is bottomed-out on the back of the hub.  If there isn't enough room you will have to remove the hub...and that's another story.

When installing the wheel, the torque is only about 60ftlbs for these 10mm studs so...

If you are talking about the stud, than most of them are pressed in. When you get the new one it will make sense. You might be able to tap out the old one, but expect to pull the spindle out to get it out.

Ok so i have the stripped bolt out but I had to cut it to get it out! You said I would have to remove the spindle! What size socket do I need to get that big nut of with the kotter pin in it?

On the Z8s they are 36mm. Remember, they hold a high torque value and you will have to hold the hub with something. I suggest putting the tire on and removing the center cap to hold the hub. The manual tells you the torque.

Finally got the kotter pin out that was a pain in the a$$ that broke now I need a new one of those and the hub is on so tight I snapped a breaker bar! Has anyone had problems getting the hub off?

[NMKawierider]

Without looking it up, if it is like most others it's close to 200 foot pounds of torque. That's enough to break many 1/2" breaker bars. But not 3/4" or torque wrenches large enough to torque a nut like that. I had to buy an air impact that puts out a 1000ftlbs of torque to get the nut of my secondary off cause my other one that only puts out 250 wouldn't. Pretty sure it would get it loose.

The only socket I found was 1/2in so even if I wwnt with a 3/8 breaker bar I would have to use an adapter 3/8 to 1/2 do you think I will be ok?

To 3/4", not 3/8" yes, the socket will take it. It's just the 1/2" bar won't always unless its a HD like a Craftsman, Snapon...ect. May need a cheater pipe too. Remember to hold the hub with something, not use the axle & diff take the force. Holding the brake on hard might hold it but I put the wheel back in and use it.
