So got caught buying cheap front wheel bearings, long story... Anyway 12,000ks later and a new set of timken bearings are in my possession, I vaguely remember the nut tension changed about 2017 , it was tight around 300nm but think it’s around 220nm now.

I did a search but haven’t been able to find a definitive number, could someone please enlighten me on the new tension on the hub nut.

Thanks in advance
Cheers Bulletman

The DIY lower control arm thread on here (sorry don't know how to paste a link in here) stated 350Nm.

I thought the Advanced Factors site states the hub nut value. Otherwise a quick call to your trusted indie should answer it.

My question is how do you get them undone and redone to spec? Do you brace off the wheel studs?

Yeah nah. Was dropped by over 100nm but I don’t know the exact figure. 200nm odd is about what I recall.
The hub nut just does up. There’s no need to brace it off anything.

I think it's 230nm.

Leave he wheels on the ground and tighten the nut I would assume.

Looks about right : LR014147 LR048083 Optimal Front wheel hub Bearing Kit Discovery 3 & 4 Range Rover Sport RFM500010 (https://www.advancedfactors.co.uk/lr014147-lr048083-optimal--front-wheel-hub-bearing-kit-discovery-3--4-range-rover-sport-rfm500010-1242008-p.asp)

"Hub nut torque has been reduced to 230Nm / 169 lb-ft, correct torque is important."

Yep, so hub retaining bolts (mount to the knuckle) @115Nm and hub to stub shaft @230Nm.

If tightening with wheel on the ground, need to make sure your socket fits through the centre cap retaining bore.

Two new front bearings are on my list too. Rear lower arms and bearings to follow soon.....

Job done today and the difference in the drive of the car is very noticeable. Last time I will get caught buying the inferior wheel bearings, well hopefully I wont have to worry for several years.
