Help with parts reference, rear axle.

[gmannino]

Hi, I'm looking to replace the section of my passenger rear rotor assembly where my lug nuts bolt into. I'm not perfect with suspension or brakes so I wanted to ask if someone was more familiar.

I looked up the part numbers on www.realoem.com but it was unclear to which part actually had the threads for the lug nuts. Can someone please look at this link and verify which part I need to order?

Thanks!

I'm thinking its part number 5, Drive flange but I wanted to make sure its not part number 1.

Anyone know the answer to this? I want to settle this asap.

1 is the hub where the rotor/wheel mounts and 5 is where the axle shaft mounts

what winfred said.

SO, if you want to replace the part that the lug bolts thread into, you want #1- SIDE SHAFT 33411134880.


Let me know if you want to go with a good used one (or both)- I have a complete rear suspension for parts.....


Thanks, Bret

if done properly you can rethread the lug holes with helicoils and have a good safe result, 12X1.5 if i remember right

I'de rather replace it with a known good condition one.
