drive shaft seal

[loren01@ix.netcom.com (Scott Bermes)]

Greetings ya,ll (just practicing for the Olympics!)

My 89 200tq sedan has a noise coming from the middle of the car when i 
let off the gas at high rpm, it also seems to be run harder at 4000+ 
rpm's than the 89 200tqw i just purchased.  There is definately a 
difference between the two and the wagon is smoother.

My shop said the sedan's drive shaft seal is worn.  Are those types of 
sounds characteristic of a drive shaft problem.  If so, is this 
something I can live with until it needs a new clutch and do both jobs 
at the same time?  Is replacing the seal the appropriate procedure, or 
does one need to rebuild or by used drive shaft?

TIA
