Rear hub nut torque setting?

[Gene1]

Hi, I have a 2011 Berlingo with disc brakes on the rear. I read that the rear wheel hub not torque setting is 300N/m but I have seen it stated higher also.

Do any of you know the setting?

My van has disc brakes on the rear - rotors and pads.

My torque wrench goes to 210 N/m. A mechanic told me to set it to 210 and then turn 180 degrees more after the click, should be in the ballpark.

I have a ALDI or LIdl air impact gun that goes to 310 N/m but not sure if using that would be a good idea, they kinda 'hammer action'. It might be ok to take off the nut to undo the peen but may do harm on the tighten.

Any ideas?

I'd rather go to the limit of the torque wrench, then add "a bit" with a breaker bar.

An impact is a bit of a blunt tool, I wouldnt use it to try and set them. It's also unlikely to reach that figure..

Do NOT guess at torque settings!
The bearings are Angular Contact Bearings, and overtensioning the hub will put a lot of strain on them and wear them down quickly.
Not putting enough tension on them will result in a wobbly axle, and that's not good, either.

If you need to buy, borrow or steal a torque wrench that goes high enough, that's what you have to do.
There's a Gospel of Haynes available that covers your car. And it's available online, too.

I've actually just googled the gospel of Haynes. I thought despite not being religious, that there was another gospel I'd not heard of in the Bible! I think I need to hang my head in shame. 

Also, I know over torquing screws bearings. Best to get the correct tool for the job, even if it costs you a few quid to buy your own. At least you'll have it in your arsenal next time you need one.

I'm not going to use the impact at all

My torque wrench actually goes to 240 N/m. I supported the extension with a spare axle stand underneath it to keep the angle of the bar perpendicular to the nut. Did both to 240 so far. I tried a few shops within a 40 mile radius and none had a torque wrench that goes that high. The local garage didn't either...

I torqued it on the axle stands. Do you guys finish the final torque with the wrench when the wheel is on the ground?

I haven't managed to find one cheaper that goes to the numbers needed, https://www.ebay.co.uk/itm/285356771472

Screwfix have a similar one for about £80 if you must have it from a local shop.


Edit - actually, I forgot about this type, https://www.ebay.co.uk/itm/125205144681 bit of a blast from the past.

I'd get yourself one of these. I got one to crank up my front hub nuts which were 325Nm according to ServiceBox. Personally I wouldn't risk over or under tightening something as critical as that

I'm getting a new torque wrench tomorrow

All you need is a bar and a bit of maths.

300 Nm = 221 ft-lbf

You need 221 lbs. of force, so that's 221 lbs. at 1 foot out from the socket.
1 foot = 12 inches.

Say you weigh 182 lbs (13 stone)
So take  221 / 182 = 1.21
12 inches x 1.21 = 14.5 inches.

Mark a line on the bar at 14.5 inches, stand on the bar with all your body weight at the line you just made, you will have to steady yourself by touching the car or holding on to something.
When the bar stops moving downward from your weight, you just applied 221 ft-lbf,  Don't jump on the bar or you will over tighten it!

And don't forget to recalculate the mark on the bar if you gain or loose weight 

This method will be as accurate as you will ever need for hub nuts.
