Service Traction and ABS lights come on

#1

I have a 2004 Chevy Venture. The service traction light comes on - the abs light comes on- it groans when braking and turning mainly - sometimes when going straight slowly- had both hub assemblies replaced. OK for a month or two - then it starts again.

Perhaps changing the hub assemblies wasn’t the answer. Those may have been the result, rather than the cause.
A suspension shop, or a transmission shop, would have more expertise on this. They can scan the trouble codes, ask the computers questions, and perform various pressure / electrical tests.

My Silhouette’s abs and traction warning lights came on a short while ago and the cure was replacing the left front hub assembly (abs sensor and all).
