Thump when come to complete stop or just starting

I just bought a 2002 Axiom XS and I have noticed a small thump or bump when I come to a complete stop or when I am just starting out. The servce department at the dealership said it is probably the abs actuator and that I shouldnt worry about it (of course). Has anyone ever had any problems like this or heard anything like this. Thanks!

This is the classic symptoms of a driveshaft slip yoke that needs to be cleaned and re-lubed. Try a search over at the rodeo forum (same driveshaft).
