Rear Hubs

[Tobz]

Hey all!

 

i am trying to remove the 4 19mm bolts that attach the Rear bearing to the rear hub. I have nfi how people do this with the hub attached to the car, all the guides just say move the driveshaft back a bit, but mine doesn’t move any further back and I can’t get a socket on the the bolts as the driveshaft interferes.

 

anyone got any ideas? Any help would be awesome!

Drop the driveshaft at the diff and pull it out.

That makes sense! I started to think that.

Any tips on undoing those damn 14mm drive shaft nuts? They are ridiculously tight!

WD40 + muscles. Long spanners & breaker bars. The usual.

Damn was hoping there was some magical trick! Will head over to Sydney tools tmrw and grab some long spanners. Have wd40’d tonight so should hopefully help!

 

thanks for the help

If you are buying new tools to undo stubborn bolts, generally 1/2 sockets and long bars "breaker bars" are the cheapest way. Long spanners exist but you have to buy each size, and they wont always get at the bolt head as they have to be flat against it, with a socket you can use various length extensions to get at the bolt head

God I’m an idiot sometimes.... socket fits on but couldn’t get my ratchet spanner on.... nfi why I didn’t just use my breaker bar!!!! (For the driveshaft bolts)

Anything that tough to crack will f**k a ratchet spanner anyway. They are not for loosening tough bolts, only for spinning in and out.

Got the driveshaft bolts undone fairly easily in the end. Hopefully will be able to get to the hub tmrw once I get some space

[Tobz]

Rear hubs suck so much! Now trying to undo the 27mm but holding the gold parking brake but on. No dice, tried the breaker bar, 1500nm impact wrench, nothing. Hoping a night of wd40 will free it, otherwise maybe heat it?

Get a 6ah battery. I used to think that they just lasted longer but they also have more oomph (torque). Not sure what nut you are trying to undo though....

Will try that if I still have issues tmrw after the WD40 has penetrated over night. Will also try some heat!

 

The nut I am trying to remove is the 27mm nut holding on the Peking Brake thing

You can always put more torque on something with a large breaker bar than with a rattle gun. If the bar isn't long enough, extend it with something like a jack handle or iron pipe.

Also, give it a bit of heat with a blow torch first, and a shock or 2 as well (put socket over bolt, hit firmly with hammer a couple of times)

BTW, question we should have asked first....what are you trying to do? Change rear wheel bearings I guess? If so you should undo the control arms and ball joints and remove that big bolt in a vice on a bench. All the other stuff like reinstalling bearings and dust seals will be easier with the hub off the car. And it will have to come off for pressing the centres out anyway

I need to remove the hubs to add a 6mm spacer for the alpha omega brake kit, such a pain in the butt! Totally should have just got the WTAC edition that didnt need the spacer. 
 

Anyway learning a lot. Haven’t worked on a car before with this many stubborn parts! So at least I’m learning!

Get some Penetrene. 11ty time more powerful than WD40. It's truly industrial strength.

[Tobz]

Ok! Finally got the stupid thing off!

even after using a 2m breaker bar, no dice. I went and bought a proper 6 point 27mm socket rather than the 12 point I had. Used some WD40 specialty penetrating oil. Used my impact wrench again, no issue.

 

pretty sure the 6point socket was the key as it had no flex in the socket at all, compared to the 12 point which just wasn’t up to mustard

Thanks everyone for all your help, ideas and support! I think I would have gone nuts without it 

[GTSBoy]

Again, 12 points are for convenience. You should only use 6 point for breaking anything (that is really tight) loose, and you should only use impact sockets on the gun.

12 points will just round nuts. Non-impact sockets can take out an eye.
