I noticed a slight noise coming from my right rear wheel while driving. I hoisted the car and tested rear wheels for any sideways movement. There was a noticeable play in right side. Contacted my local repair shop where they quoted 190€ plus some 120€ for parts. I decided to go and try it out myself. I found the hub for 63€ from online shop (www.pkwteile.de) plus 9,95€ shipping to Finland. It was an original SKF hub VKBA 3644.
The change is quite straightforward with right tools and can be done in under one hour. You will need to have your car lifted up, because it will be very difficult to achieve needed torques with car only jacked up from one side.
I'll have the pictures to talk for me.
You need to take the brake caliper off. First undo the double nuts with two wrenches to remove the pistons.
This is a good way to position the wrenches so that you can squeeze them open. Remove the brake pads.
Next remove the brake caliper frame. It is fastened from the inside with torx-bolts.

I used fairly large torque wrench

Next pop off the dust cover from the hub. Nevermind damaging it, as a new one is always included in hub set.
Next remove the brake disc. It is fastened with one torx screw.
Once the dust cap is removed you can see the hub bolt. This is a pain in the a** to remove because of the torque. Opening requires a special XZN M18 head. I bought mine from local auto parts store for 15€. Do not try to use anything else.
XZN M18 1/2" bit
I used longest possible wrench to loosen the bolt. Still i had to hang from the wrench with all my weight.
Once the hub bolt is removed, the hub slides easily off from rear axle.

New hub (VKBA 3644)
Install the new hub on the axle and use supplied new bolt. The bolt needs to be torqued to 180 Nm plus 180 degrees. I managed to get it to around 120-140 degrees over the torque with long wrench, a pipe as an extender and LOT of force. The bolt is meant to stretch in place, thus the insane amount of torque.
Install the brake caliper back.
Install the brake saddle, the dust cap and you're done!
Hi there! Many thanks for this clear report! I have to do the same job on my 2016 Touran, and I was especially afraid of the requirements of special bearing puller/pushing tools, but your story made me sure I can do it myself. Searching the internet, so far I only found the instruction video of SKF themselves, where they mentioned a special pusher tool (from SKF of course..). The only thing I'm wondering is the size of the bearing bolt, as far as my information goes, the size of it is XZN M16. Also good to read that you must be prepared for a large wrench in order to be able to loose/fasten same bolt. Thanks a lot one more time!
