Following on from the helicoil timesert repair thread I have decided to do the job properly and replace the hub housing and a new hub wheel bearing., Instead of repairing carrier bolt thread 

 

The dealer could fit a new wheel bearing hub into new hub for £50 which is off car and seems reasonable. The cost of wheel bearing is £125 and hub housing is £140. I ve seen the vag gen 2 tool for sale for £50 to 70 online, non LASER.

 

Q can anyone tell me/ confirm the size kit I need? Quick search seems to suggest 72mm. Does this relate to the diameter of drive shaft? Car is Fabia vrs 1 .https://m.ebay.co.uk/itm/UK-New-Front-Wheel-Bearing-Tools-72-mm-for-Audi-A1-A2-Seat-Ibiza-VW-Skoda-Fabia/201908736056?ul_ref=http://rover.ebay.com/rover/1/710-53481-19255-0/1?ff3=2&toolid=10044&campid=5338268676&customid=c240daed-0454-45ae-988f-72168c07206e&lgeo=1&vectorid=229508&item=201908736056&srcrot=710-53481-19255-0&rvr_id=1686048385210&rvr_ts=27712cd91660a9cb3181e014ffe9ce95&_mwBanner=1&_rdt=1&ul_noapp=true&epid=27011066866

Q2 anyone recommend a link to a wheel bearing kit? Only advantage to doing job myself would be if other front wheel bearing goes.  It would be nice if kit would do all vag cars as I have an Octavia 3 but the laser kit seems to be £500 mark. This is not a common repair on wheel bearing so perhaps buying just for Fabia is the way to go or getting dealer to fit.

 

Q3 Should I buy genuine wheel bearing or £90 option from Andrew Page brand FAG

Q4 ABS sensor that goes into hub housing. I've be read these break easily. Any tips on removing carefully?

 

Thanks

Cheap gen2 tools on ebay and amazon, never tried one though.

 

Gen2 unique to fabia, roomster I think, octavia different arrangement, so you might only ever use kit once....

 

72mm is hub diameter

 

Good Youtube videos on gen2 how to do..

 

Check pr codes to ensure correct part...

How badly corroded the material round the ABS sensor is will determine whether it comes out intact or not, I'd probably have an unopened spare on hand if it was me doing the job, and time was a factor. 

While you have it all apart, check that the dust seal for the bearing (plastic disc on the end of the  outer CV/driveshaft) isn't too bent and distorted by rust of the bit it's sitting on; have heard of ABS sensors getting machined away by this bit if they distort too much.  Replacements can be had pretty cheaply from Skoda, might be worth having one of those on hand too. Will find part number for you if you like. Here you go, https://www.skoda-parts.com/spare-part/6q0407623e-washer-seal-skoda-10685.html

The seller states it fits all Fabia 1 years from 2000 to 2008. So looks ok

dust seal for the bearing

Wino, is this the plastic dust seal? Looks similar and FAG wheel bearing hub kit came with it and new 35 multipoint nut.

Thanks

Is it recommended to grease the hub as it is pressed into hub housing/swivel hub using gen 2 press?

Thanks

Yep, that's the seal. The bit it pushes onto will probably need a fair amount of de-rusting, take some photos when you get there please. It's good that it comes with the bearing kit, I didn't know that.

A bit of grease will help the fitting of the bearing, yes. Into anything but a new bearing carrier, you'd also want to be cleaning up the inside bore thoroughly.

 

Thanks Wino. 

 

Also use liberal grease on the thread of the "force screw" that is part of the Gen 2 kit, I'd get an ABS sensor as well to be sure as the last 4 ive took out have all snapped, despite lots of cleaning and soaking in advance. They are cheap enough for a non gen and I've had no issue with any I've fitted.

 

Make sure what ever wheel bearing you buy that it has the metal snap clip which I designed to clip into the hub when the bearing is drawn in fully. I bought two Borg and Beck bearings that came without them and had a hell of a game getting the seller to swap them. 

 

FAG bearings are OE so you'll be fine with one of them.

metal snap clip

Yes, FAG bearing has this. I was wondering about when would I know the hub bearing is seated in housing. Did this job today. Took me 5 hours with breaks and lunch .

The wheel bearing was pressed into place in 5 mins. I spent 30 mins watching videos. It did indeed snap into place. Very reassuring.

I bought a Delphi ABS sensor £25. The join with cable at the clip broke. The plastic is brittle. Used a bit of sealant , not ideal, to ensure it does not part with vibration. No contamination big electric contactT he

 cable disappears into wheel arch so not sure how to replace if I decide to and cost.

I managed not to damaged ball joint and track rod rubbers using scissor parting tool.

Test drive tomorrow. 

Hub nut torqued to 50nm plus 1/4 turn for power steering assisted vehicles.

The only surprise was the plastic ring at end of CV joint that could file down abs sensor. It was slighly different design to one supplied with wheel bearing kit. I left old one in place as it was in good condition.

 

I recommend buying a new one from dealer for anyone replacing hub wheel bearing. Diameter was almost identical, but 2 mm bigger diameter.

 

Test drive tomorrow. Fingers x

 

 

That's one Job I decided I would pay the dealer to do....(besides the timing belts)..

 

Just too many one off tools & too much stuff....

 

mind you I did remove all the brakes, springs, dampers, wishbones, rear beam axle.....& then derust, hammerite, polybush, all new bolts, top mounts ball jonts etc..Konis...ebc discs/pads...

 

so I suppose a bearing job is easy....just couldn't get my head around the tool cost as was then ...around 2006yr...

Car is fine. ABS light extinguishes more quickly after replacing sensor. 

 

The braking is returning to normal as caliper carrier was loose and pad not perpendicular to brake disc.

 

If anyone is using a generic gen2 bearing kit you need to use the silver clam shells and larger thrust nut that is in the kit.

Gen2 wheel bearing kit , non LASER , cost £40 . It is 72mm hub kit. The dealer wanted £50, but I would had to have bought a £125 wheel bearing.

As I bought a new hub housing, all I needed to do was press in the bearing. Far easier job than the rear axle bush I did last year.

I have a set of tools I can use on other wheel bearing if it goes.

..I found the rear axle bush ok..& did it without tools...

 

sorry correction....just remembered.... I made my own puller up...like the bought tools...

Have replaced both bearings (original FAG to aftermarket FAG) few years ago and didn't used that included dust seal.

Maybe, it's mentioned for another car, which uses same bearing  (??)

Just cleaned grooves in old plastic (grey-green item in photo)- and that's it.

 

For replacement used self-made tool, which looks like half-plates No.3 and big tube No.2 (like VAG original tool).

It's bit different than another execution from Laser, SKF etc, which uses pins (in photo from bmbmdmb).

 

Not sure which models will have the 6q0407623e dust seal versus the one you guys have found, I can't spot another type other than a smaller one in the parts catalogue so far but I have vague memories of having seen reference to a green one.

 

This is the post where I saw the (dramatic) rust/distortion/machining of ABS sensor problem: https://www.volkswagenforum.co.uk/showthread.php?t=29529&p=100440&viewfull=1#post100440

White=new=thin seal is included in FAG bearing set.

Old=grey/green=fat :-) is original > mine looks same and both drive shafts are still original from 02/2007...but have no idea why to touch original seal if it looks ok.

It could be 6Q0 407 623 B   but in Google can't find exact photo for ID with "B" in the end :-/

That part number looks right to me, and was superseded to the E suffix in 2008 after all mk1 Fabias had been made, so that fits with your info.

 

As you say, if original looks good, leave it alone.

;-)

If it's interesting, original front bearings started to get "gone" (=when started to make a noise on turns) 177'300km/7years7months right side and 220'000km/9years8months left side.

Looks logical since LHD car catches holes/bumps mainly from right side of road.

Also slightly relevant: https://media.repxpert.de/media/01_media_master/closed_area/01_work/02_service_info/fag_5/pdf/pdf_en_6/fag_0007_-_fitting_instructions_for_front_wheel_bearing_sealing_ring.pdf

 

 

Yep, I remember this sheet (maybe it was included in bearing box?).

Since FAG started it- why "fitting instruction" doesn't show how new seal ring should be fitted? :-DDD

I couldn't get the plastic dust seals to stay on the driveshafts on mine, they fell off and ended up just hanging loose next to the bearing and I thought they would damage the ABS sensors so I decided to leave them off. No issues so far but I'm aware that crap might get in and affect the sensors eventually.

 I have just changed the front wheel bearing on my Mk.1 Fabia and noticed with the driveshaft out that the ABS sensor protrudes a long way into the hub carrier, and while the rear plate for pulling the old bearing out has a flat it is nowhere near sufficient to clear the sensor so I used a 3/4" drive socket under that plate against the hub/bearing assembly inner face. The reason for doing this is that information suggests that trying to remove the ABS sensor generally results in it being destroyed.

The plates to reinsert the new hub/bearing do not impede on the sensor area.

 If using a socket as a spacer this introduces loadings onto the bearing in an incorrect manner so it should not be re-used.

I bought a Delphi ABS sensor just in case, but despite penetrating fluid and thin ended flat screwdrivers to ease it out, it was obvious it was going to break. I think a Delphi sensor cost me £25 . The rust produced over time pinches the old sensor. The plastic ages and gets brittle. The ignition ABS amber light on dash extinguishes quicker with new sensor so money well spent. Delphi seem to be a oe brand as I've seen ECU on other cars with their branding.
