Hub flange....press or tap in?

Discussion in 'Suspension, Brakes, Wheels & Tyres section' started by Chri5, May 25, 2016.

  1. Basically, the hub flange (the bit the wheel bolts to) that fits into the wheel bearing, does it need to be pressed in or will it tap into the bearing?

    The reason I ask is because I'm replacing the swivel hubs and pressing new bearings into them.

    However if the flange also has to be pressed in, it means I'll need to remove both hubs first and do it all together :unamused:
     
  2. took between 4 and 5 tonnes on my press when i replaced my wheel bearing - that's both the inner and outer races.

    I'm sure you would be able to tap it in, but i personally wouldn't because of the risk of damaging the abs ring.

    I'm assuming you'll be changing your wheel bearings if you plan on removing the wheel hub - you won't get it out without destroying the bearing.
     
  3. Yes I have 2 new wheel bearing kits coming too,which include the ABS ring,the wheel roller bearing and I believe a new hub nut.

    What do you mean by inner and outer races? If it's just the 1 bearing?

    I best get stripping the swivel hubs off before I even start then :sweat::smile:
     
  4. by inner and outer race, i mean you'll have to press the bearing into the hub (which contacts the outer race), then press the axle flange bit into the bearing (which contacts the inner race), both operations took 4-5 tonnes of pressure.

    I did mine a couple of weeks back and my swivel bearings were surprisingly in like new condition visually (i was expecting a rusty mess like i've seen on picture before at 112k miles), but the needle rollers did fall out as soon as i pulled the swivel hub out of the main casting, luckily i'd already bought the replacement swivel bearings too, just in case :tongueout:

    Good luck, it isn't that hard of a job to be honest, an hour per side really, the hardest part will be getting what's left of the inner bearing race off the flange, just follow the swivel hub guide on turborenault to get the swivel hub apart.

  5. Ok, had a go at doing these today, but managed to fluff one up :smirk: and damaged the bearing. I know my mistake now but want to check the procedure before I do the other one.

    Getting the flange and bearing out was easy,but as you said getting it off the flange was a bit of a mission but we got there in the end with a puller and some heat.

    Ok so the best way to refit is as follows yes?

    Place bearing flat on the press bed.
    Invert the hub and place over the bearing (with abs ring loosely in correct position).
    Put bearing press dolly/solid cylinder onto the flat ring inside the back of the hub.
    Put slight pressure on everything with the press and triple check alignment,squareness,abs ring position etc.
    Press bearing in until it's flush with the outer surface of hub (this should then hold abs ring in place without crushing it?)


    I think I screwed it up when i fitted the flange.....I would fit it the same way , upside down on the flat bed. How do you control the depth it goes into the bearing, and not over doing it and squashing the abs ring or pushing too hard on the inner ring of the bearing and damaging it?

    Better order another bearing kit :neutral:
