Title: ABS rear speed sensor
Post by: gtiscott on 16 April 2008, 23:32: need to replace the right rear speed sensor but have a couple of questions...

1. on eurocar parts website there are a few options varying in price from Ã‚£10-Ã‚£50, which one do i need?
2. i have changed the front one before, is this one just the same procedure?

cheers
Scott

P.S its for a '97 16v gti

Rear works exactly the same but is harder to get out due to access.... I would remove the rear disc if you know how makes it so much easier

Post by: mark3valver on 18 April 2008, 14:13: yeah the best technique seems to be aim a flat blade roughly in the direction of the sensor and smack like f**k till its in 50 bits and there is a nice hole waiting for the new one lol

Post by: Pete Taylor on 18 April 2008, 23:17: There's a lot of guides about for mk3 abs sensor removal but they're all a bit of an effort..

This is the way I do them..

(http://i16.tinypic.com/525vmdz.jpg)

When you have the sensor retaining bolt out, poke a screwdriver through one of the wheel bolt holes in the hub (one of the square ended screwdrivers that a ratchet head fits onto) and if you spin the hub around (car jacked up in gear with handbrake off) then you can feel the ABS sensor in there! Swift knock of a hammer and it's out! No breaking bits up, no removing calipers or discs and takes half the time

Post by: gtiscott on 19 April 2008, 08:35: cheers pete, will give it a go :smiley:, where is the best place to put the trolley jack to give maximumspace to work in?
Title: Re: ABS rear speed sensor
Post by: mark3valver on 19 April 2008, 08:50: just use the trolly jack to get it up then stick axle stands to be safe...

I wouldn't ever work with a car on any sort of jack.... nearly had my fingers cut of before by a brake disc hitting the deck, not funny

Post by: gtiscott on 19 April 2008, 12:21: yes i will use axle stands but wheres the best place to put the jack to lift it? also vagcom says right rear sensor, is this the drivers side?

sorry for such dumb questions but..... :smiley:
Title: Re: ABS rear speed sensor
Post by: Pete Taylor on 19 April 2008, 13:20: yup drivers side mate, make sufre you look at the route the wiring for the old sensor goes before you pull it all out to put the new one in
Title: Re: ABS rear speed sensor
Post by: gtiscott on 19 April 2008, 17:05: thanks pete, i thought it was, now where do you place the jack?(never jacked up the back before) and where do you place the axle stand?.... also is it still best to use something against the front wheels to stop them moving or does having it in gear do this.

:embarassed: :embarassed: i feel real dumb asking such daft questions but if i don't ask, i don't learn :grin:

Post by: mark3valver on 19 April 2008, 17:45: dont be mate - i have been working on my own cars for years and still managed to drop it off its widow maker jack last weekend - luckily landed on the old disc that was being replaced!!!

If you slide the trolly jack in you can use the actual jacking point but I prefer to go directly in towards the middle of the car in line with the jacking point and there is an obv flat bit to use to jack it up. I then put the axle stands where the rear beam connects with the chassis, lower the jack on to the stands then I lift the jack up to the point where it just starts to take some of the weight again as a second defense (i get paranoid about the weight of a mk3 on my face)

others may do it differently - possibly better

Post by: gtiscott on 19 April 2008, 18:07: thanks mark3valver , can you just lift one side and use one axle stand? or is it better to lift both sides?
Title: Re: ABS rear speed sensor
Post by: mark3valver on 20 April 2008, 08:21: will if you are doing the rear would be best with the handbrake off so you can spin the disc so I would just jack up the wheel your doing and axle stand that, then put some jocks in front of the front wheels and put it in reverse....
