I am going to have a go at tightening up my hub nut, as dave did on andie's car. I just wanted to make sure my tools would suffice for this job. I don't have a torque wrench but i do have a socket set. Just wondering would this and what size is the hub nut. Or can i just use an adjustable spanner?

Cheers guys!

You'll need a socket due to the fact it's resessed inside the central bit.

It's a high torque setting so make sure it's done up well if you don't have a wrench.

ideally you'll need a torque wrench but if its loose tightening it without one will help.

it'll be big probably 24mm+.

what you'll notice is it has a split in it, this needs to be hit with a chisel or some other angled tool to bend the sides into the groove, this stops it from spinning off

Ok I might just leave it then. The noise is just starting to become unbearable! But it goes in next week for a service etc so I guess it can just wait until then, unless the wheel is likely to fall off! :sad2:

wheel wont fall off, but if it is loose and comes off a driveshaft might pop out.

take the wheel off, inspect the split part make sure its in the groove and pressed in and just see if you can move it by hand, if you cant then its probably fine but get them to check at service

Dont forget the hub nuts are staked into the shaft. You need to drive out the staked part.

They are around 215 Nm to re-torque and a new nut should be fitted, then staked

Torque wrench of that size is big money, best to leave until the service

I got my hub nut tightened today, 15mins of driving later and the noise was back :shake: would the next step be to get a new hub nut??? I don't think the bearing has gone as when it was all tightened up again the break disc didn't wobble or move? If i do need to replace the bearing does anyone have any idea how much it is going to cost me???

Thanks

Then either the thread holding the nut on is damaged, or its something else like the wheel bearing.


P.S Adjustable spanners are for travelling persons, throw it in the bin....

Bearings are around £50, but there is a good chance the drive flange would need replacing too as these are quite often damaged by the failed bearing.
I had a bearing and drive flange replaced eariler in the year at a local independant MG specialist and it cost the thick end of £250.

I would try replacing the nut as they are not expansive. Part number should be EJP7738 and Rimmerbros list them at £1.80inc VAT.

Thanks! I shall try replacing the hub nut first and then look at the bearing.
