Very helpful video. I especially appreciate that got the camera in there up close so viewers can actually see what you were doing. Many videos like this are obstructed by the Mechanic's hands in the way in tight spaces which is why pausing to show the details with the hands out of view is how videos should be done. You deserve the thumbs up and subscribe

[@diydaly]

Glad it was helpful! thankss for the comments! much appeciated 👍👍

[@TheJdni]

Exceptional work and great description. Thank you.

[@diydaly]

You're very welcome!

[@kevinpalmer7452]

It’s good to see that it’s not only me that has to deal with the rust on older cars. Those spline bolts can be very difficult to remove that centre hub one I’ve nearly lifted the car off the ramp many a time. Great video 👍

[@diydaly]

Haha these rust issues can be the bane of our lives at times!! Just spent an hour removing a seized caliper slider today! 😅ha .. thanks for the comment Kev 👍

[@henrymarks587]

Best video I've seen to date as far as any car repair. Filmed perfectly, great lighting and great attention to deal. If only all repair videos were of this quality. Many thanks mate. Really helped me out

[@diydaly]

Thanks 👍 your comments much appreciated , makes all the hard work worth while ! 👌

[@matthewlatham920]

Great video, really helpful for me just changing the abs sensor over. WD40 worked a treat just soaking in and loosening it off. Thanks mate!

[@diydaly]

Glad it helped! thanks for the comments 👍

[@lespriteveille.1602]

Hi, thank you for this helpful video, I live in France and it help me a lot to know what sort of tools I need. Thank you again and good continuation. Chaoukri.

[@diydaly]

👍👍🙌

[@starwagon]

Just did this on my 09 Rabbit 2.5L with 240K km (150k miles). It's a Quebec car and while it's not the rustiest example, it still took me nearly 30 min of prying with a screwdriver very slowly to get off. Honestly not that bad of a job, just super scary. I had to do it super gently in order to not snap it off. I had TC, ABS, e-brake and steering light on, and it would be stuck in limp mode, but after replacing both, it fixed the issue. Also, due to the previous owner not replacing the hub, the old sensor was literally shaved off from the rusted magnetic ring, so yeah.

[@diydaly]

👍 glad it sorted all your issues

[@Jim_Kay.]

Clear and concise, great tutorial. I was wondering how I'd figure out which sensor was acting the maggot - live data and a turn of the wheel with an eye on the obd.. Cheers!

[@diydaly]

👍👍 nice one thanks

[@noel5ilv3rlake]

I’ve been living since almost 22 years close to the beach as 4 seasons also included but all my cars don’t rush like this or whatever somewhere in British I saw many of them especially, I just wonder, my 20 years old audi, 17 years old R53 and my little S1 they are still good without heavy rusty! God safe mine !

[@craigsooman7901]

Excellent video. I’m about to try this, but I don’t have a ramp. Would removing and reinstalling the calliper be practical with the car jacked up and on a stand?

[@diydaly]

Yes easily done without a ramp 👍

[@toeknee6588]

Had some good fun with those bolts over the years,had to cut one hub off once, then weld a large nut on the end of the bolt to get it out, the back side of the bolt is open to the elements so can rust bad : (

[@diydaly]

Haha had similar issues myself! 👍👌

[@lindameehan949]

Good we job

[@diydaly]

Thanks 👍

[@jimscott6831]

Great

[@diydaly]

Thanks Jim 👍

[@davidbarthel9976]

Very helpful, I assume VW is the same.

[@diydaly]

Yes, it is mate

[@ianrimmer1968]

Good video mate. 👍 I didn’t think that hub bolt was going to come out. Why do people over Torque fasteners 👿

[@diydaly]

Thanks for the comment Ian!👍😁. I know! Unfortunately it’s an issue we have to deal with on a daily basis! 🙈😩

[@fickyrisher]

Thanks for the video, professionally done 👍 I am looking to get a new bearing & hub, however I'm not sure if I should get one with our without ABS ring? I have removed the hub and the bearing from a 2007 Octavia VRS and is rusted to f**k, the sensor bolt snapped as I was removing it 😒 But I have found the replacement (pa66-gf25 ATE JT7), I have found the replacement hub (1LL, 136mm, 27.5mm, bores x4, holes x5, bolt 112) However there are 2x options the difference being one says that it has ABS ring and the other does not Should it be obvious to see if the current bearing has the ring?

[@diydaly]

Yeah it’s quite obvious mate , it has a large ring on the back for the sensor to pick up from

[@fickyrisher]

​@@diydaly Thank you, been fighting with the rusty triple squares (common thiam!), so couldn't see the back of the Hub, however, re-watching your vid 3:53 you explain what to look for, I sent off for a new Hub and Bearing kit with ABS 👍

[@diydaly]

@@fickyrisher nice one 👍

[@Tuchh]

You don't need to remove the carrier hanger.. the disc slips off once the pads are out.. only need a 13 Spanner to whip off the caliper bolts.. easier 😆

[@diydaly]

Thanks

[@alyasbungo]

Hi. What year audi a3 is that? And what spline bit socket did you use? Thanks

[@diydaly]

Size 18 for the hub bolt mate , it’s a 2004 I think

[@andykeith7315]

Great vid thanks, what your view on eBay bearing at £30 v euro car parts at £70 also the same with the abs sensors less that £10 vs £30. Is it just euros overpricing for non trade?

[@diydaly]

👍 Thanks.. hard to say really depends what brands your looking at really.. there are some really cheap non branded parts on Ebay, obviously the Euro do sell some "white box" non branded parts but they also offer some decent bits.. there prices are normal reasonable

[@squadmeta]

Buy direct from SKF Aftermarket. Just paid less than £50 for basically OEM bearing.

[@squadmeta]

If you heat that bolt with a heat gun it releases the loctite, then a long solid breaker bar should do the trick, if the bar is bending buy one that doesn't as the bending just loses torque. Not everyone's got a 3/4" rattler!

[@diydaly]

Thanks for the comment

[@dandyer8351]

3/4 bar is all thats needed ideally one that doesnt bend.

[@telece]

Why didn't you replace only the ABS magnetic ring? It is available as a separate part.

[@natedog7638]

Weres your garage I need my done 😁

[@diydaly]

Haha im on the east coast in Lincolnshire!

[@RayTitske]

so many rust that car .
