Andrewwynn i had the symptomps that i told you and before and after changed wheel bearings..

Which doesn't exclude a flakey wheel speed sensor.

If you can tell that the oddity is happening on one corner, I would swap the sensors and see if it swapped sides.

Yesterday i removed the front driveshaft,the abs switch,the transfer box switch and i changed the rear diferential...the problem it's still the same,nothing changed...my mechanic have no ideea what to do next...
