Disco 2 Traction control

Need some advice had lower suspension ball joints replaced on d2 td5 however since then the traction control was kicking in non stop making car nearly impossible to drive. Suspecting the garage (world worst garage) may damaged ABS sensors decided to replace both the front ones now have the 3 amigos. Any ideas on what could still be wrong?

Oops!
Do you have access to a diagnostic of any sort?
Was any other work done at the same time?
Are all tyres of the same type, at correct inflation and are wheels properly tracked?
If not get this done then come back to us.
Sadly replacing just the sensors may not correct the problem, the little bugres are SO sensitive.

Without a nanocom or similar you may struggle. I had to replace both front hub bearings to sort my TCS issues out

Sadly no access to diagnostic all tyers are the and matching psi. I'm thinking the garage may have damaged the hubs while doing ball joints.

B4 panicking and going to a lot of expense just do the tracking. Ought to be the only thing the garage could have put out and, tbh, any garage could have done that.

A couple of Mots ago I used a garage near work. Ended up changing a hub seal. They also screwed the abs. Are the sensors fitted correctly?

The garage have really screwed the car up. The new sensors are all fitted correct.

Getting short of suggestions.
Wondering if it is possible that the garage damaged the sensors from inside the hub somehow.
Would take it back and say "It ain't right, the three amigos have been on ever since you had it and they were not on before you had it." If they are decent they'll find the fault and correct it.
You don't have to have either a Nanocom or a Hawkeye to diagnose hub sensors, a Foxwell pro 520 will do it far cheaper, I klnow I got one for precisely this and it works well, even more reliably, allegedly, than a Nanocom.
Once you've found which hub/sensor is the problem, get back to us and we'll try and help you again.

Sensors, shuttle valve, but i would take it back and let them sort it.

I note that quite a lot of posters on this forum mention the shuttle valve, the getaround they have done on it and then report "but it made no difference".
Is there anyone out there who can say what causes the shuttle valve to be an issue and whether or not a garage working on an axle could have somehow caused a problem with the shuttle valve?

NB replacing a sensor without replacing the whole hub is not the official way of doing it. Some do it with success, but quite a few don't and we then have posters getting on and saying "put lubricant on it when you do it", and /or "tap it with a rubber hammer to seat it", etc etc. To be absolutely sure of the sensor working you have to replace both hub and sensor and as the Count says, make sure the number of gaps on the reluctor ring matches the ones on all other hubs as apparently there are, or were, some out there with the wrong number on. A hub can wear sufficiently to cause a sensor problem but not be easily discernible to a person's hand even one who is experienced at wiggling a hub and saying "yup, that's worn". We are talking 1/2 a mm of movement here being the edge of what is enough to upset the sensor.

I suppose it could also simply be that the garage didn't tighten them up to the very high torque they are supposed to be tightened up to. If so this would be the easy fix, relatively, except for the cost of a new stake nut, but the question "How tight did you tighten them up to?" is a valid one.
Best of luck
