BMW diff removal
I'm part through disassembly to get my BMW diff out, in fact, the next step is the diff bolts themselves. Before I crack on as per all the guides I've read, is there a reason to remove diff and carrier from the car rather than remove diff from carrier? The latter would be slightly smaller to squeeze out and also would leave all the centralising shims in place. Or am I missing something?

Have you got John Vine's note about the correct placing of the Schnorr washers?

Hi

I recently took my BMW diff out leaving the carrier in the car.  This was  fairly easy.  I took the A frame off to give more room, which was also easy.  The problem was to get the diff back in.  Plan A was to leave the carrier in the car.  However, this turned out to be very difficult.  Plan B was to take the carrier out, fit the diff to the carrier and then fit carrier plus diff back in the car.  This wasn't easy, but it was possible. 

I think the reason that Plan B worked better than Plan A is that there is no give between the diff and the carrier, but there is some give between the carrier and the chassis.

Luckily a fellow member with much more skill and experience than me helped.  Many thanks Graham.

Hope that helps.  Good luck.

Ivan

No I haven't, in fact, I don't even know what they are! Sounds like I should though... please. :-)

Ah, OK, thanks for that. Makes sense. I must admit the wrestling back doesn't fill me with a warm fuzzy feeling.

Hi

Just one other thing.

When you put the diff back in take care to keep both parts of the handbrake cable above the diff carrier.  I didn't and I had to take the cable out after I'd got the diff back in and re-thread it through the right gaps.

Re JK's post (#2) on Schnorr washers....

The latest IKEA-style Assembly Guide has an error on page 95.  It omits the two Schnorr washers for the lower diff bolts (green arrows):

The previous (2015) AG said:

"Attach the front end of the differential at the lower mounts; use the M12x55 capheads from the Z-Pack 30Z1067A (copper slip the shank). Take care to use M12 Schnorr washers underneath the head of the bolt."

And this is a Schnorr washer:

Thanks all, diff is out! Not nearly as heavy as I gave it credit for. So, next question, what's the preferred method of getting the back plate off? It seems gummed up pretty tight with sealant gunk.

Hi guys, Resurrecting this, I have just got everything ready to drop the diff but there looks no way it will come out between the de Dion, A frame and the chassis parts at the front. What Am I missing?

Do you need to remove the A frame to allow it to swing a bit sideways?

I removed the A-frame to take mine out, only takes a couple of minutes to take the 3 bolts out.

What about the ARB? That seems to be in the way too.
