Seriously, everything that could have gone wrong this weekend has.

I'll update the issues I've had shortly but currently the hub and knuckle will not seperate from the drive shaft. I've tried bashing it (ha!) And I now have a 3 claw puller on as hard as I could (like shortly a crap load) and then bashed it again (ha!). No luck. I then left the puller on and heated it up with my propane torch for about 5 mins. And bashed it (ha!)

So the puller is still on. I was hoping that the constant pressure over night might help? After that I'm at a loss.

(Btw bashing it with a heavy plastic hammer so drive shaft and thread safe)

What the hell do I do now?

Thanks

Did you take the nut off?

OK kidding! But put it back on so it is just before level with the end of the driveshaft, then bash that (straight on) with a heavy metal hammer

Nut is off but I did leave it there to bash earlier. I'll try my little sledge on the but but it sits recessed into the hub so hard to hit with anything sizely. 

In that case, leave the socket on there and bash the back of the socket :) (hopefully its an impact socket)

Its tricky to give specific advice without knowing the exact setup (which model skyline is it?), but I guess it is something like aluminium on steel galling, so heat and shock are the answer

Yeah der me. Can definitely leave the impact socket on and bash that.

Do you have something like this to help you push the axle out? 

 

Yep I have a puller on now that I'll leave over night. It's as tight as I can get it. 😞

Hit the end of the puller with a hammer (serious) while it is tight. You'll find once you shock it, you can retention the puller tighter, then repeat the process.

I was actually going to ask that considering it's adding pressure. I'll whack a socket on the end so I don't kill the top. Thanks!

Dumb idea but what if you use some refrigerant out of an air duster can upside down to cool the axle instead of trying to heat it? I did that with my rear block heater pipe and it helped it work loose.

Ok, so I made some progress. I managed to get the hub/knuckle off but not before pulling my whole bloody driveshaft out of the diff, but thats another problem.

This is the BMW E90 rear hub / knuckle set up;

And this is the hub / bearing;

https://www.realoem.com/bmw/enUS/showparts?id=VB33-USA-08-2006-E90-BMW-330i&diagId=33_1231

My question is, I managed to press the bearing into the knuckle and then I started to press the hub into the bearing (which was seated in the knuckle) and it was slightly off straight, so I stopped and when I took the hub out, it took the top of the bearing with it. Nothing seems wrong with the bearing, just appears to be a cover. It seats perfectly fine back on there and after pressing the hub in again (straight) everything seems smooth and quiet. I have a spare bearing (always buy 2 when you break things as often as I do) and wondering if I should swap them over?

Thanks guys.

    • There are black hose clamps as well if you care. Plazmaman for example sells some: https://plazmaman.com/product/black-hose-clamps-premium-quality-stainless-breeze/
    • After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive 
    • Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.
    • I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.
