E53 ABS/DSC Sensor/Bearing Issue

[Rockabilly Rebel]

Hi guys,
would need a bit of help here please. '05 X5 E53 4.4L.
A few weeks ago, the steering started shaking when I'd brake at around 50-60 mph. I changed the left thrust arm and ball joint (because they seemed looser). Test drive showed improved performance but still some shaking, so I went ahead and changed the same on the right side....


The *$&@!!!! CV axle was jammed in there stupid-stuck, I had to knock at it like a Spartan for hours. When I finally got it outta there, the tip was unusable. (no shit?) So I replaced it also. When I got it all back together, the shaking was gone but now I get a trifecta light show (ABS, warning, 4X4) with the DSC inactive. The way it happens is when I turn on the ignition the lights stay off but when I drive away, after about 15-20 feet the trifecta comes back on.

Scanner registers issue with front right sensor. So today, I took the assembly apart and blasted compressed air in and around the ABS sensor to clean it up. Now the trifecta comes back on after say 250 feet of driving.

The sensor registers the wheel speed at the same speed as the 3 others (checked with Foxwell NT510). Also, the scanner states that there is no DSC signal at the transfer case.????

Can the ABS sensor be bad but still register wheel speed? Or bearing mechanism? Or should I look elsewhere?
Thanks in advance guys, take care!
