Rear Hub to trailing arm bolt torque

Recommended Posts

Hi everyone,

My apologies for my first post being a begging post!

I am trying to confirm the torque spec on the 4 bolts that hold the rear hub/bearing assembly to the trailing arm on an '09 Focus.

I am pretty sure it is 110Nm but this seems a lot for an M10 bolt.

If anyone can definitely confirm this I will make a step by step picture guide of the job as a thankyou!

Thanks in advance folks!

Do you mean the 4 bolts that fix the hub assembly to the knuckle?If so I would imagine it’s similar to my MK1 and a torque of 66 Nm 👍

The wheel hubs need to be tightened using the following procedure:

 

1586000323_Hubtorque.thumb.jpg.4ce89eec1c642f4a86c326f02c9689e2.jpg

Step 1: Torque: 65 Nm

Step 2: 
Stage 1: Loosen: 90°
Stage 2: 65 Nm

Step 3: 
Stage 1: Loosen: 90°
Stage 2: 65 Nm

Step 4: 
Stage 1: Loosen: 90°
Stage 2: 65 Nm

Step 5: 
Stage 1: Loosen: 90°
Stage 2: 65 Nm

 

This procedure is needed to avoid introducing stress/deformation of the wheel hub housing during assembly. This will reduce the risk of premature failure of the wheel hub drastically.

Well, that all looks a bit fancy.

Last time (and only time) I did that rear wheel bearing job, I just tightened them up as tight as I could and that was it.

Perhaps I am in for early failure, but I doubt it.

Especially on my driveway! And I'm too old to be messing about on the floor! 

You could've let your son do it himself...just take a supervisory role instead! :biggrin:
