Front wheel bearings

A few years ago, I bought a set of front wheel bearings as I was getting a bit more than usual road noise. I remember being a little surprised that they had 'DAEWOO' printed on them, but as I was assured they were very good, I fitted one side which did make a difference. The other side seemed ok so I didn't bother with that one.

Last weekend I used Sparky to move the groomsmen around at my sons wedding



There was a little more noise on the nearside than usual over the 550 mile round trip and when I got home I discovered this -



I've never seen these oily marks on the wheel before, so as they were on the same wheel as the noise, I thought I had better investigate. I still had the spare Daewoo bearing so stripped it down to find -



This was a bit disappointing :? Upon further inspection I found that the inner race was loose on the shaft and had actually left some score marks on it -



So, do I throw the Daewoos away, get some better ones and bond them on with loctite? or are the Daewoos ok? or do I need a new upright?

Where did you get the Daewoo bearings from?

I certainly wouldn't loctite the bearing inner track on.

I think I would get good quality bearings from a reputable manufacturer, through their retail outlet (or direct from them if online) such as Timken or SKF and then see how they fit on the stub. If they're not loose then you should be OK with the pillar.
It's difficult to tell the extent of any damage to the stub from a picture.

You can only see the damage, you cannot feel it with a fingertip, so I am hoping it will be ok.

I did actually buy the Daewoos from a reputable Rover P6 specialist supplier and questioned the manufacturer when they arrived, saying that I was expecting Timken or similar. Looks like I should have stuck with my guns at the time.

I'll find some Timkens tomorrow.

I'd hope he supplied sold them in good faith, and it's easy to get caught out with things like that. There are loads of fake parts out there and it can be difficult to tell if that's what they are, but if you look at the "DAEWOO" and "MGM" the letters don't look stamped in line with the visible machined edge. They look high at one end and low at the other which just looks a bit odd.
 
By the looks of the grease escaping your bearings were running hot, caused by wrong type of grease or incorrect bearing end float (ie. Hub nut too tight) or over packed with too much grease in the hub. The grease in your bearings looks a bit black?? Which indicates overheating, what kind/colour of grease did you use??

I used Timken bearings when I did mine last, the inner bearing is a SET6, LM67048 - LM67010

The outer bearing a SET2, LM11910 - LM11949

The SET6 and SET2 refers to a set of matching inner and outer race, and may also be a common size for trailer/caravan hub bearings.

Grease to use is a LM high temperature bearing grease. The letter designation has changed over the years but it should be an amber coloured grease of which I used Castrol Spheerol HTB2 (here in Oz), (which replaced Castrol HTB). Best check the Castrol UK website for correct UK designation.

Front hub end float (as per my Haynes book) should be 3-5 thou. You should feel this play when the wheel is back on by holding the top and bottom of the tyre and rocking the wheel.

The bearing inner races that fit onto the hub shaft have to be loose So you can fit them on the shaft, hence the shiny marks you see are just from bearing creep and are not usually indicative of worn shaft. And loctite should not be used as the bearing are meant to creep and your hub shafts look OK.

The taper roller inner races should be packed with grease and the hub cavity half filled with grease and pack the hub grease cap.

I can't remember what grease it is, I usually use the stuff that comes with the bearings :)

The Daewoo bearing wasn't just a loose fit, you could rock it on the stub, albeit a very small amount. I have received a new bearing, thank you Mark Gray quick and efficient as usual :D This one doesn't rock so seems to fit better.

I do actually wonder if the grease escaping was to do with me hacking the rim of the bearing cap off to get it to fit under the Vitesse wheels, but there was something wrong with the bearing so hopefully the replacement will have cured it.

I have set it up ok, just need to bleed the brake and ran out of dot 4 last night. I fitted some standard discs when I was at it to see what it sounds like without the demented cricket song. Time will tell 8)

 
Good stuff, sounds like the Daewoo bearings, as you say we're wrong size if they were overly loose compared to the later ones you acquired, when I mentioned they should be a loose fit I ought to have said a neat but sliding fit, hope all is well now.

Hi Scott

Both discs changed with new pads, driven to work today, no bearing noise, reduced road noise and the crickets have now left.

I don't know what the discs are like performance wise against the Rossinnis as they are new and need to bed in but the sound reduction is excellent :)

I'll keep my eye on any grease leakage for a while 8)

Surely, when you fitted discs named after one of the most famous Italian composers, you should have been expecting some "background music"?

Sorry, I'll get me coat . . .
 
Well Richard you never stood a chance, what with the Rossinni connection and the Daewoo connection, how could it get any worse a great composer and a piano manufacturer just had to be music in that combination.


Who stole me coat!
