Re: rear end noise

[Mitchel Seff <ms6453@optonline.net>]

Hi Grant,
Generally, a thumping or consistent noise that is in time with changing 
speed ends up being either the rear hub bearings or a U-joint. Inspect 
the U-joints for looseness or play. To check the rear hub, jack up the 
car and grab the tire from the top & bottom, then rock the tire back & 
forth. This play should be minimal, almost none. If the play is 
excessive it's probably the hub bearing.
