Hi, about 5000 miles ago while I was routinely checking my car over I noticed the n/s front wheel bearing was a bit loose. I adjusted the centre nut and tightened it a bit so I could feel and hear but not see any play.

I wonder now if the very slight brake drag I've detected on the same wheel is related to the bearing, I haven't jacked it up yet. Does the fact it required ajustment mean it's worn out, there's no noise or rumbling. Should I have repacked it? How hard are they to change, can you remove the caliper without having to disturb things in a way that requires Star? It's an SBC system, thanks.

I've decided to repack the bearing with grease. Can I just fill the cap, force it on and then remove and scoop out the excess? I'm not really up for dismantling the hub, and anyway thanks to the SBC braking system removing the caliper seems a no go.

Plus, do I have to use the special green grease, or can I just use a generic lithium molly type of product? Thanks!!!

You can grease the small front bearing . The rear bearing requires a strip down and a new abs ring fitted. If you over tightened it the bearings fail in a very short time. The green grease is heat resistant and the reason its used.

I haven't over tightened it, I think I left it too loose. So is the grease MB only, I don't know much about the stuff TBH, I've been very lucky with wheel bearings so far!! Thanks

Do you know what it's called? It's green, that's all I know!

Thanks, I ordered the cheaper one. Right, so I'm going to repack the front race, nip the nut up, spin the disc, back the nut off a little bit and then drive off looking foward to another 150,000 miles?

There is apparently an “amount “ of grease which is correct , don’t ram the whole tube in :D

The grease arrived today, I've cleaned out the front race and repacked with grease. I've adjusted it three times now, there is still a bit kf play you can feel but not see. Given there must be quite a lot of wear, 150,000 Miles, should I just leave it now? I presume once there worn there's a limit to how tight you want to go in comparison to after replacement? thanks
