Not a 100% guide, but any half decent machine operator will be able to figure it out within 30 seconds when you show him the photos.

Today we had a long roadtrip - and vibration is gone. Thanks to Siltech and suberb customer service. They were claimed for 100£ import tax even though I clearly stated the freight as RETURNING GO

All of the HiSpec hubs I had contact with when building my car had errors, but I fixed two of them to put on my car, and the other two were given to someone else who did the same.   In my ye

We are on to something here. Good quality and service always pay off. Check the non-runout from Siltech. I'm pretty impressed.

No problem - I know what it's like!

Scroll past the exhaust stuff...

 

The lathe chuck holds the hub using the outer outboard bearing race, there is a complete bearing (outer, needle race, inner) inside the 'inner' part of the hub (facing towards the upright), with a big 'spike' in the drill chuck to keep it square and solid. You can then machine off the disc mounting tabs and hub face, with the lathe and drill chuck spike having made what is effectively the stub axle in your upright.

You are gold!

 

Is this Hispecs, no?

And how much did you remove. How much was it out of order actually?

Yes, HiSpec.

 

I took off enough to make them flat again.

 

I measured run-out earlier in the thread.

@AdamR I grabbed my self a couple of beers and read your Lobster thread. Why isn't there channels/tv just showing stuff like this 24/7? I want a lathe for sure.

Update:

Siltech replied to my mail in the way I was hoping. They take customer service serious. 
They were very surprised and could not believe their hub was the cause of vibration and needed to investigate. Nice approach. 

So on their request I sent the uprights, spindle, hubs and bearings towards the British Islands and Siltech. Both sides was sent..

Either way I will get a perfect non-run-out set back they promised. Hoping they take a late summer holiday. So far I'm happy.

Good reputation is always better than fancy webpages.

Here's an update.

 

I sent the package from Norway 6th July and it was delivered 24th July. Thats a long time even for these crazy Covid times.

The package was stuck for a long time with customs in UK. And later on customs claimed Siltech for 109£ in import taxes. What?!

I had clearly stated this as a RETURNING shipment and no taxes should be claimed. Instead of waiting for me to sorting this out Siltech paid the tax and accelerated the delivery. I did not expect they to pay for me in advanced. They will later claim the taxes back. Thanks to Siltech! If no luck I'll help them get it refund one way or other.

 

Luckily for me Siltech did not take any summer vacation so they went straight on checking my hubs. They confirmed the runout on both hubs. Puh, my dial indicator works :)

They could not believe it them selfs. Next day they investigated the runout and concluded that both bearings were faulty. Now after the exchange theres no runout and happy days. 
They will pack it up and return it back to me any time soon. So far so good!

Yes, after my understanding.
