Good job, though I'd use a hammer and drift I'd remove the outer when installing the inner and bearing to reduce mass and the possibility of brinelling the new bearing, a press is better if you have one.
I left the cup on to help reduce the chance of dabris getting onto the rollers during the drifting process. Any brinelling would be minimal due to the inner cone being drifted, not the outer cup. A press would be the best bet but I don't have one at home. Besides I thought I'd use tools that are likely already in the average home machanic's arsenal. Freelander SE 2005 Auto.

It's not a Defender wheel bearing is it?
Do you still have the numbers of the bearing handy?
Defender, Discovery 1 and RR Classic appear to use the same bearings and are only about £10 each if bought for that application for Genuine TIMKEN BEARINGS LM603049 / LM60301.Freelander SE 2005 Auto.

Learnt a new word: brinelling. "To make a permanent indentation in a surface".
Me too, will be using that this week with my metal working class.

One wonders how many "almost good diff's" but for the sake of one bearing, have been replaced at great cost, and have been scrapped.

I had already ordered one in anticipation

It's not an ideal bearing for the job it does, but my D3 has done 175K miles. After doing my diff by removing it and stripping it on the bench. I now think I could well have stripped it while it was still fitted to the chassis mounts. To do the failed bearing, only the LH side casing needs to be removed. The 14 casing bolts are all accessible from underneath. It should be possible and would save stripping the RH side suspension and having to lift that heavy lump back into the chassis.Freelander SE 2005 Auto.

Fair enough, though it's the weight and vibration from the reflected shock that might cause an issue, even though you were on the centre (inner) cone. False brinelling might also be an issue if the vehicles been transported a lot.

Well I've got a bearing should I need it. I predict that my front diff will get noisy in the next 3 yrs, so by that time I'll be 45 and retired ( I wish), and I'll have lots of time to deal with all these type of things then.

My RRC has 225K on it and I bought with 90K and it's never had a wheel bearing in my ownership. It's had proper good leathering too. I guess the difference is in a wheel bearing setup it can be adusted.IID PRO

It would seem they take more of a pounding in a D3 diff...
