TCS and ESP/BAS light on after suspension work

[Señor]

I had a backyard "mechanic" try to change my front lower ball joints but he ****** literally everything up and now when I start to drive the vehicle, I hear a quick grind noise and then the TCS and ESP/BAS lights come on and then it doesn't grind again until you turn the truck off and back on then drive again.

I assume he destroyed one of the wheel speed or ABS sensors, anyone else have any ideas what it could be?

Rough way to learn my lesson about people "doing me a favour" by working on my vehicle when they're not licensed mechanics.

Might want to trace the wires and see if one isn't plugged in. I changed my own on my KJ without any issues and I am not certified

Sounds like a speed sensor.

Agree with the above. The wheel speed sensor pigtail might not be connected all the way. It's located on the back of the plastic fender liner at the top, attached to it by two christmas tree connectors.

Ditto with the answers...

I actually changed a sensor myself. Those connectors can get pretty grimey, for obvious reasons.

If it is a loose connector, grab some canned air, clean out both ports and push together until it clicks. Lock the tab and you should be set.

Hopefully that works. Good luck.
