I have replaced my front wheel bearings, I reckon they are adjusted down too tight, tiny vibrations and slight shudder at speed through the wheel.

Using just a big adjustable spanner, I'm guessing the nut should be tightened just until you cannot grab the disc with your hands and move it in and out on the stub axle? Still seems too tight to me. Is it ok to have some play in this area? How do I know they are adjusted right? I know the nut is meant to be pretty loose.

Also, when you lower the back, I remember reading that the rear control arm bolts should be loosened and re-tensioned. Are you supposed to do this after lowering the car (to the floor) and raising it back up?

Thanks guys.

with a torque wrench you're supposed to tighten to 30Nm (I think) while rotating the disc so that the bearings set in properly. after it has been tighten, you have to undo the nut a full turn and then tighten the nut up finger tight. The brake disc should be able to spin freely, but without horzional play.

Not sure how you can do it without a torque wrench, just don't do it too tight to the point you break the bearings.

They should be seated in by now, I have driven it around a few times and I did tighten it up and do that. I'll undo them and do them finger tight and try it.

Thanks Phongus.

Use a large adjustable wrench an tighten the nut with it positioned vertically.

This way you cant apply too much torque.

Not sure how much finger tight would be measured in, but in the book it says 5Nm or something...don't have the book here but cbfed getting it. To me that doesn't seem like much, so I tighten it up as much as I can with my fingers and leave it at that. Haven't had any issues with it.

No problem.

Yeah I'll give that a go tonight after work.

Thanks again.

Seeing as you've got the bearings sorted, to do the rear end you need to run it up on a set of ramps, loosen, roll it back n forward a bit/bounce on it, then tighten.

It is important to follow the correct bearing adjustment procedure as specified in the Ford
Repair Manual.
1. Remove the wheel where necessary.
2. Pry off the hub dust cap.
3. Remove the split pin and nut retainer.
4. Loosen the bearing-adjusting nut three turns. Then, rock the wheel/hub and disc in and
out several times to push the brake pads away from the disc.
5. While rotating the wheel/hub torque the adjusting nut to 30 Nm to seat the bearings (step
1. in diagram).
6. Loosen the adjusting nut on-half turn then re-tighten the nut to 1.5 Nm (steps 2 & 3. in
diagram).
7. Selectively position the nut retainer on the adjusting nut so that a set of slots lines up with
the hole in the spindle (step 4 in diagram).
8. Lock the adjusting nut and nut retainer with a new split pin (step 4. In diagram).
9. Check the wheel/hub rotation. If the bearings rotate properly, install the hub dust cap.
Install the wheel if necessary. If the bearings are rough or noisy in operation, clean or
replace the bearing assemblies as required.
10. Lower the vehicle.
11. Before driving the vehicle, pump the brake pedal several times to obtain normal brake
lining to disc clearance to restore normal brake pedal travel.


Its still requires a torque wrench but gives you some idea...

Cheers...
