Wheel bearing / hub question
Afternoon all,
I'm pretty sure my OSF wheel bearing is on its way out. I'd like to investigate and replace it myself this weekend. I've seen the procedure on the Wiki and it seems straightforward enough.
I did see that the original hub nuts are 32mm, but saw it mentioned that new drive shafts required a 34 or 36mm nut (can't remember which off the top of my head) ?
I have the original drive shafts, does anyone know if the front hubs / bearings come with the smaller nut or the larger?
I don't want to begin the job if the new hub (not yet collected) doesn't have the correct nut...
Thanks

Timken hubs, at least, come with both nuts. Same thread diameter, different thread pitches. Replace like with like.
Hub nut torque reduced from original 350Nm to 230Nm.
If you have 32mm nuts they are staked. They can usefully be loosened by using a socket through the centre of a fitted wheel which is in contact with the ground. One contributor has reported doing this without the need to first remove / refit the wheel to unstake the nut.
Edit As of September 2023 a Timken hub supplied by Island 4*4 came without nuts. Paddock Motors are offering to include 2 nuts.

Thanks for the info, wonder if I should've gone for a Timken but SKF was the best my local motor factors had in stock and thought I'd give it a go. I seem to remember the guys at LR Time saying their SKF bearing had only lasted 40,000 km so I might be doing this again before long!

Well, OSF wheel bearing successfully replaced. Old bearing was pretty nasty, lots of noise when turned so happy to have it replaced with a new one.
BUT the oscillating rumble I've been hearing on the motorway (particularly noisy under load around 65-75mph) is still there. Next on the list I suppose has to be to check other bearings, I was convinced it was OSF.
I'm thinking it could also be front diff, drive shafts, transfer box...
If anyone has any other suggestions let me know please!

Rear prop shaft? Either the joints or the centre bearing. Have a look. You can only really tell by taking it off to look. Richard

Thanks for the tip Richard. I'll have to explore that route I think. Passed the MOT the other day with no advisories that would suggest a cause of the noise...
Will update when I've had a look.

Well Richard,
I think you‘ve officially called it…
Is this (prop shaft centre support bearing) the source of my annoying thrumming noise?! Looks to me.
If so is this something I should be looking to do on my driveway? Or v difficult?
Best
Chris

Not too tricky, bolts at either end will be tight. You'll need to lift one rear wheel clear of the ramp or ground to be able to rotate the prop, so you can get to all the bolts.Richard

Cheers
Any views on favoured brands for a new prop shaft, or any to avoid?

There is a kit you can get that allows you to change the bearing separately, can't for the life of me remember what it was called or who made it though... was linked to on here late last year..I want to see the sweets before I get into your windowless van... I'm not stupid!

GKN is the favoured reliable brand.
Try Advanced factors, site sponsor?

Think I may just go for a new GKN, and then try to refurbish the old bearing as others have done and keep the old prop shaft as a spare. Thanks chaps.

I'm about to order a new GKN propshaft to replace on the drive in a couple of weeks - but I've just seen it doesn't come with replacement bolts - do I need to order some separately or can the old ones be reused?
It's about £27 for a full new set from JGS4x4.
