problems with auto trac control

[jklberry]

i have a 2006 explorer xlt. give you bak ground in the last part of november the explorer had abs trac lights on and would kick in and out of 4 by 4. figured it was a bad wheel bearing since we knew one was going bad. changed out front drivers wheel bearing. took care of the abs problem but wasnt the wheel bearing that was bad (humming). few weeks went by and noticed that when turning (mainly right) it would make like a whining noise and trac light would sometimes come on and it would like jump. like it was trying to engage 4 wheel drive. i assumed it was the bad wheel bearing that wasnt replaced. so had the passenger rear wheel bearing changed (humming went away). but we still have the problem of when turning that it acts and sounds like it is kicking in and out of 4 wheel drive. does it mainly turning right but will do it sometimes turning left. every once in awhile the trac light will come on during this. mind you this is on dry pavement so its not due to snow or rain. any and all info and advice would be great.. thank you in advance

What DTC's is it giving you when the lights come on? What engine do you have on the 06 and how many miles on the vehicle? Also, you didn't do both the front bearings, but the passenger rear and the drivers front? Typically when you replace one front bearing you do the other side since it most likely has a lot of play in it too.

I dont know on the codes. As for the motor its is a 4.0 with like 117 thousand miles. As for the wheel bearings yes i did the front driver side and the rear passenger side. I basically. Changed the front driver side thinking it was bad (it was accually the rear one ). I was basically wondering if it could be one of the three speed sensors and if so how can you tell?

Find out what DTC's it has and then you will be able to figure it out. Odds are that the issue is related to the other front hub bearing that you didn't replace.
