[MBZ] rear brake is driveaxle

[Neal Kramarcy]

Well list I want to thank all who had great suggestions and admit I'm 
feeling a little stupid.  When you get the same noise before you replace 
a driveaxle and then it returns it's best to assume that the new 
driveaxle has failed.  Yes, that's apparently the problem.  My inde 
listened then put the car on the lift and let the axles hang and the 
noise disappears.  I guess I was too sure that the axle was ok since the 
noise returned in 6 weeks of replacement of the driveaxle ( about 
1000-1500 miles) and if the old one lasted 25 years how can one fail in 
6 weeks.  Well, that appears to be the problem.   Last night I jacked up 
the rear end using the differential and left it overnight.  A quiet ride 
this morning.   How many miles will this treatment give some relief, I 
don't know.  And I don't think I'll do the experiment.  On the bright 
side, I 've certainly learned a lot about the rear brake system.  Now to 
deal with the supplier of the driveaxle.  Again thanks for the help.
