Default Discovery 1999 Rear Rotor replacement

Looking for some info on the last steps of replacing the axle nuts and lock washer.

What happens if you forget to do the float adjustment by spinning the rotor and instead just tighten everything up...

Thank you

From RAVE:

13. Fit hub adjusting nut. Tighten to 61 Nm.
Back off adjusting nut 90°. Tighten to 4 Nm.
This will give the required hub end float of
0,010mm
14. Fit a new lock washer.
15. Fit locknut. Tighten to 61 Nm.
16. Tab over lock washer to secure adjusting nut
and locknut.

If I'm reading correctly you just tightened the adjusting nut and locknut up and called it good. That isn't the worst thing in the world but if it is too tight you can cause premature wear on the bearings. Too loose and you will have play /wobble.

The truth is all you have to do is take the 5 lugs off the wheel, the 5 bolts off the axle shaft and the nuts will be right there. You may need a new paper joint washer (gasket).

Part of the process is to squeeze out excess grease to make sure you have solid contact with the bearings without over tightening and creating excess wear. Most do it by 'feel'. Tighten, give the rotor a spin, should have some resistance but should still 'flow'.

Unless you went total 'gorilla' on the inner nut I wouldn't worry about it.

Thank you, and yes I tightened the inner nut to "snug". I will re-do it, so it is done right
