Collapsed front wheel bearing confusion

Hi all.
I developed wayward steering on just before the 200 mile drive to my sons wedding this weekend and found the wheel bearing lock but loose. Is the crushed nut type whic had been reused a couple of times by the look of it. I did it up tight and off we went. Yesterday 400 miles later the inner bearing broke up as we pulled in back home (jammy)
I had a kit so last night I replaced it.....
However the inner had spun on the stub axle welding it self on so I need a new stub.
My question is. What should a 2004 td5 90 have. I have back to bank taper roller bearings a crush but ans a stub with a flat on it. Is that the correct set up as I see some have a needle roller bearing?

The hub has two tapered roller bearings held apart by a spacer and a single retaining nut with a flange that can be knocked down onto a flat on the stub axle to stop it coming undone. The needle roller bearing holds the driveshaft steady and is inside.

Perfect! Thanks Brown

I can’t find a drawing anywhere for this single nut set up. There is no spacer between my bearings? No wonder they burnt out! I need to check all 4 now. Can I buy a spacer separately?

I believe there are a variety of thickness spacers which are selected to give you the correct pre-load o the bearings. If you don't have the spacer that may explain your issue as to why the nut was left loose. Looks like you have two options
1. Buy a range of spacers and trial fit until you find the correct one.
2. Convert to the twin locking nut configuration on that wheel

If you go option 1 then fit a new set of Timken bearings at the same time. Doing that will mean that any future bearing changes will be easier as there shouldn't be any need to fiddle around with the spacers if you change make. (Timken are a quality bearing manufacturer so have consistent bearing sizes)

Option 2 will require you to buy two locking nuts and a tab washer assuming you have the large thick washer/spacer that goes between the outer bearing and the nut.

Worth a look at the other wheels just to be sure!

This should give you a start, spacer sizes are on the next page
