That used to be the case. But they did a service bulletin some time ago making them a replacement item. That pic I posted was from that bulletin.

I'm on my phone at the moment not my computer but can upload it if you want it.

I know about the service bulletin regarding the sensors, but I was thinking more of the bearing. If the bearing is not serviceable and a new hub is required, it would come complete with an ABS sensor mounted correctly.
Or is the bearing now serviceable also?
 
Well, I spoke to him at lunchtime and the part had come in at midday and they were going to look at it after lunch. So I called again at about 4.15pm and he said for me to go in to see him in the morning (8.10am), as it hadn't worked and he wants to go over it all with me and show me what's what. He couldn't talk about it then as he had to dash off to collect someone. So it's the computer then.... so I'm guessing fecking LOADS of money!! I am completely and utterly depressed about this. I know it's only money, but it's more that I HAVE to get to Cornwall on Friday night, as my Mother is getting married at midday on Saturday. My life will not be worth living if I miss it...

Ah sorry see what you are saying. Yes your right it would come with the sensor as an entire part.

Good luck getting to the wedding! I suspect it's not the ECU but the shuttle valve. Which can be repaired. By the way I drove mine without working ABS for months.
 
The Wabco fault codes are accurate - dont you think the indy would be looking at the shuttle switches if the codes pointed at them ?
 
Just back from seeing the man what knows. The shuttle valve switch was replaced and it didn't fix it. He's had an auto electrician looking through all the wires that come off the computer and it's not any of them. So it's having a new computer.... I will hopefully have my truck back tonight.

So that new wheel bearing hub, complete with ABS sensor, new rear suspension sensors, sealed sunroofs x 2, SVS and a computer, plus £240 of labour.... Oh and for free he's checking all the levels, tyre pressures and also he's sorted out the stiff steering, by taking off the (buggar, forgotten what he called it - it either goes to or comes from the steering box) something arm? and soaking it in grease and putting it back.

Thank GOD I work somewhere that gives good bonuses and we get them tomorrow... Not that I planned to do this with it....
 
FYI there's a really good guide here for replacing the front wheel bearings (with ABS sensor):
www.discovery2.co.uk / Front Wheel Hub / Bearing Assy

My Disco (174000 miles, 2002) has had both fronts replaced, and one rear (one rear still original).

Neither of the fronts caused the 3 amigos. Just a usual knackered-wheel-bearing-rumbling when cornering.

It was the rear hub that caused the 3 amigos, and it too was a knackered bearing allowing enough play to upset the ABS.

As the time of the last (rear) hub failing, I actually called Ashcroft Transmissions to see if they were interested in doing a reconditioned-advance-replacement for the hub, but at the time they weren't interested.

With so many older D2's now, I would have thought a Hub Refurb service would make a fortune! A business opportunity for someone!
 
Thanks for the link - though it wouldn't be a good idea for me to try any of that unsupervised :lol:

I should have taken photos of the hub and wheel bearing that they took off - it was proper fooked! It only started making a noise 10 days before I took it in and he couldn't take it that week, as there was no courtesy car for me and he was pushed to the limit.

Fingers tightly crossed this works!

I agree the codes are accurate however it will only point to an electrical failure of the SVS. It won't tell him if its actually the SVS thats failed or the signals to the SVS. If he is not familiar with the failure of the circuit board on the modulator that supplies the SVS, he will change the SVS for fun until he decides its something else.
Fault codes in general are fantastic for pointing you in the right direction but they are not infallible and still need some good old fationed nouse in order to solve the problem. Unfortunately today many garages are run by technicians and computers rather than mechanics.

I think you'll find that most LR indies who get involved with diagnostics will be familiar with SVS problems on Defenders,Disco's and Freelanders - they all do it.They also know that if a Wabco fault comes back then there is a reason for it - unlike say Valeo Hevac on P38's or EAS on the same car where a code can have many often totally misleading faults logged.Every tech doing diagnostic work SHOULD be aware from the start that codes are just a guide,its just that some systems you get to realise that the codes WILL have a good reason for logging.
The other point I would make is that most indies know other ones or have access to trade forums where they can get good info quickly - there is no reason for them to struggle on a car thats been out of production since 2005.Most issues with them are well known ,its just old age problems that are catching out the unwary now - such as Storm ecu's dying of old age for no apparent reason.
 
Once again I agree but I can't help thinking this guy has missed something and is now stabbing in the dark. Without seeing the car and diagnostics and testing the switch I obviously can't be sure but I suspect the modular circuit board. A similar thing happened to mine, I did the wiring mod (cheaper and quicker than sending the modular away) and no amigo's since.
