I went to Brooklands Mini Day yesterday, I recently have just overhalled all the brakes and wheel bearings, I finished the night before the run to brooklands went perfectly well Even managed 3 runs up the test hill grin emoticon .On the way home my rear wheel bearing started Juddering on the A3 to the the M25, coming up the slip road on the M25 the Juddering uts had became drematically worse so I assumed it may be the wheel nuts had become loose so I t...ightened them on the Hard Shoulder on the M25 Not the most "ideal" Place to do it carried on up the hard shoulder merged out and continued up the 25. i pulled in at Cobham Services and going round the harpin into the services the back of the car felt as if it was going to "Disconnect" from the front as soon as I entered the service i examine the Wheel and the bearings were completely, Well I'm gonna use a "Technical Term Here" there "*******" So I ring RAC the Patrol Turns up get the wheel off and the bearing had disintergrated and Welded itself to the inside of the Hub and the Castle Nut... So i got recovered home this morning whilst stripping it all down the Castle Nut Had to be drilled out as it as welded to the washer released it and pulled the hub off and half the bearings are still attached.
So i rang Mini Spares and spoke to Ivan who was more than helpful, after giving him a List of the parts that needed replacing he was happy enough to send me replacements of all the parts required; NEW Rear Wheel Bearings(TIMKEN), Wheel Studs, Radius Arm Stub Axle RH, Rear Hub & Rear Wheel Cylinder. and also sent me replacement bearings for the LH Side also for no extra cost!! In the 5 Years of owning Minis My 1997 Rover Mini Cooper 1275Cc & 1980 Austin Clubman Estate 998Cc I have never had this issue with any of Mini Spares Parts before and I would like to thank Ivan for his quick and fast response and sorting me replacements in the post that day.... if anyone else had this issue please PM or post a response on here Thankyou

Ive had this mate, i ended up splashing out on a pair of specialist components billet alloy ones with bearings(less than half price) and since then ive had no issues.
I broke down at London 2 Brighton last year. It took me ages to get it off the axle!!!! The old bearings were from Minisport.

Our last pair of rear wheel bearings lasted about 5,000 miles and 10,000 miles. The first one at 5,000 miles collapsed and the other just sounded rough.

Ive had aftermarket bearings last 500 miles. The timkens I have on now have done over 10k

Bummer on the Wheel Bearing Failure there mate, not a good end to an otherwise great day.

 

I'm not sure what brand of bearing that was and certainly, like the other guys here, I've also have VERY poor life from non-Timken Bearings.

 

However, if I can suggest after looking at the photos of your Hub here, it looks to me like it over heated and a very common reason for that is over greasing, ie, too much grease.

 

While difficult to quantify 'how much grease' should be put in to the bearing, as a guide, only 50 to 65% of the bearing should be filled and no more. Excessive grease will cause over heating.

 

In regards to Timkens, yes, that is all I will ever run after trying the cheaper ones. On our Mokes, we frequently do long trips in them and while I shouldn't say so, overloaded as well (typically 1200 kg on the weigh bridge), sitting on 110 kmh (~60 mph) day in, day out. I've only just looked at those in my own Moke, which has done 25 000 km now and is good as the day I put it in.

 

Here's a Timken Guide on Bearing failure, apologies that it is lengthy, however if you don't want to be put to sleep reading it all, flick through to page 23 where the discuss over greasing.
