Hi guys sorry so late im a farely new membet but all of a sudden my abs lite came on speedometer quiy workin and i got alot of vibration and loose steering (more than normal)

We need a little bit more information on your truck. year, 2500/3500, upgrades, tire size, sand or weight balance on the tires, etc.Depending on the year of your truck, you can have up to 3 different sensors for the ABS, 1 on each of the front wheels, and on on the differential. However, there are some out there where the speedometer hookup is on the rear of the transmission.Check the inside of your tires for mud/grime buildup, this will see if the imbalance can be taken care of fairly easily. Check to make sure that all the wheel weights are still on the tires and you haven't brushed one off.Others will chime in.

sounds like a hub unit took a crap on ya and tore the abs sensor up. jack up that side of axle and check for any play, if there is dont drive it, have it towed and repaired. shouldnt be no more than $500-700 for parts and labor.

Where are you at maybe one of the family here can meet you and help you fix your problem.

I would have to agree with the wheel bearing theory with what little info you left. Hopefully youve got things figured out by now, let us know how you make out!
