Try a bit of penetrating lube or a little bit of concentrated heat? Just be careful with the heat and penetrating lube together........

Is it a good quality socket and ratchet you are using?

Recently got these for a completely rounded over-torqued bolt some lovely person had left for me. Wouldn't work on everything, but nice to have in the tool box. Come in 2 sized sets. Hit them on well with a hammer and they bite into the bolt with the fluted cutting teeth. https://www.amazon.co.uk/Irwin-Bolt-Grip-R...B0000CCXVZ

A standard 3/8s ratchet can be quite small, get a 1/2 inch adapter and use a bar, something with longer leverage without a ratchet mechanism that could go wrong. Is it definitely a 13mm? I haven't checked as i'm a new owner, make sure a 12mm doesn't fit on first. You'll know if it's a dodgy 13mm socket if you can see rounded edges on the bolt. Don't go for budget sockets, a decent bit of a torque through them and their kerpoot! |

Step 1 is to get a 6 point impact 13 MM socket

I just read what Grue wrote and the extractor set that he identified should be option 3 The drill should be option 4 Option 1 --> 6 point impact 13 mm Option 2 --> 6 point impact 1/2" (may require a hammer to fit) Option 3 --> Grue extractor More details on Option 2 The 1/2" socket should be 12.90 mm The fill plug that I removed measures 12.83 mm Note: a 0.07 mm gap is very tight Let us know if it works Thanks Paul |

Thanks all for the great suggestions. The socket I used was not the best quality, so I will buy a new one tomorrow and will give it a go. I will report back with the result.

I snugged mine up and then went an 1/8+ turn beyond as I installed a Dimple magnetic plug and plan on checking it fairly regularly. For some reason, I also remembered 18 lb ft of torque. You will need to replace the copper crush washer. |

If you want to know the specification from the manual

Yay, success! I used a bit of WD40, left it for a day, then got a proper good quality socket, which did the job. But man, it was tight!

That is why you should undertake jobs that you can do yourself then you know they have been done & done correctly. |

If you have a "seep" where the haldex mates to the rear diff, there are four bolts that hold them together with a seal in between, LR02888. I can't remember if you will have easy access to all of the bolts in situ without removing the retaining "cradle", but if you do, you can try to snug them up. If that's where the "seep" is, it's likely haldex fluid. Get the service manual for your model year downloaded from this site and search for the torque values.
