Default Front wheel hub, spindle, seal, brake dust shield...order?

1984 242

I am in the process of putting new parts onto some front coilovers. I do not understand the correct stack up with the hub parts and brake shield parts.

Does the rubber seal go first, directly contacting the inboard side of the spindle? Or does the brake shield go on there first?

Then, what is the correct orientation of the brake shield spacer thing? Does the flange point inboard or outboard?

From what I can gather, I have been led to believe the seal goes on first, then the brake shield, then the brake shield spacer (flange facing outboard), then the hub assembly, then the rotor.

I've made a diagram to help explain what I think is the correct install order

The brake shield goes onto the steering knuckle first. That dust shield goes on next. The seal goes inside that dust shield and just presses against the sheet metal cup piece that goes in the hub after the large bearing. The flat side of the seal goes against that metal cup piece. Make sure it is lubricated with grease so that it doesn’t burn up from friction. It is a really crude set up.

Okay so: large shield -> seal -> cupped shield -> hub assy?

Like this?



I have the rubber seal inside the shields, on the spindle itself. I need to lubricate that rubber seal, correct?

Also, do I need to pack the inside of the hub, between the inner and outer bearings?

You don’t really need to pack the entire hub. It isn’t going to help. Just make sure the bearings are well packed. And yes, you need to lubricate the seal surface that goes against that metal cup that sits against the bearing. That lets it slide easily against the cup. Your order of assembly looks correct to me in that picture.

Okay and the rubber seal sits flat against the inner bearing washer/cup, so the flanged side faces outward? Do I need to press the rubber seal into the hub? Or should I slide it onto the spindle?

The seal has a tapered face and a flat face. At least the OE seal does. Instal the seal with the tapered face towards the steering knuckle. The flat face goes against the flat sheet metal cup that goes over the bearing.

Got it. I cannot believe how many questions it has taken for me to understand such a rudimentary process.

Ok I am confused again with the seal.

This is what I am working with. Is this the right orientation? The seal does not seem to pop into place; is it just supposed to sit on the metal washer?

You have the seal backwards.

When Volvo introduced this type of seal on the 140/164 there was some confusion about how to install them so they issued a TSB.

Thank you for that. So if I understand correctly, the flimsy side just sits on the bearing washer? Or do I need to put the seal on the spindle, then install the hub?

Yes, The flimsy side it goes against what you were calling a washer. And yes, push it on the spindle first all the way back and wipe some grease on the face of it that is going to go against the washer, as you call it. Then, install the hub assembly.

Thanks again. That is how I had it originally, but I doubted myself and erred on the side of caution. Thank you both (and Jaughlin via text message) for the reassurance.

I fill the bearing cavity with grease, just greasing the bearing will not leave you with a lot of grease. Road bumps centrifugal force etc helps spread the grease. When I put the seal on with some grease on it I push it on most of the way and let the hub seat it.

Thanks. I ended up following the greenbooks on the grease suggestions. They also said to fill the grease cap half way full.
