A lot of conflicting info on this?
So whats the torque setting for a 244 2004 front wheel cylindrical
bearing. My torque wrench goes up to 200 nm?
Ive seen from 150nm plus 35 degrees to 370nm. Its a 28mm thread btw?

M28 thread 370nm m33 thread 420 warning Iv known both sizes to strip the threads on driveshaft even known shaft to snap tightening m33 size to correct torque

Fiat told me 370nm for the maxi and 350 for others!

Took a 8ft scaffolding bar and all my weight to get one off. Did the same putting it back on. I think the torque setting is overkill.

Not if you’ve had your Wheetabix Torq

Just been informed by a Fiat dealers mechanic that untapered bearings are not to be torqued up to a high value like 370nm
Just tighten the nut up as you would any nut normally and bend over the disk to stop it moving its only against the drive shaft and not the bearing
If you overtighten it will heat up and prematurely wear out

Taper roller wheel bearings are only tightened lightly.

However

"Normal" spherical ball wheel bearings do require full correct tightening.

With is what in Newton Meters?

My version of eLearn quotes similar values to, those previously given by whine0. M28 x 1.5 = 350Nm, and M33 x 1.5 = 400Nm. These are minimum values of the quoted range with some rounding, not mid range.

When faced with a similar task on a Talbot Express many years ago, I used an extension tube on a 3/4" socket T bar, and stood on it at an appropriate radius, so that the product of my weight, and the length of tube between my foot and hub, was equal to the required torque.
