In Reply to: How do you test a guibo? posted by Joe on August 29, 2001 at 06:53:30:
My hope is it's the guibo (rubber donut?) I hear BMW's have, but have never seen. If I put the car up, can I crawl under and move the draft shaft around and see if the guibo is going bad?
If it's not been replaced in 109k miles, it needs doing anyway. We replaced ours at around 61k on a '95 525ia (it wasn't destroyed, but showing cracks). Others have waited until it completely disintegrates, and had their driveshaft fall out. Not a very good idea. Usually it presents itself as a growling noise and/or vibration when it's going bad, if I'm not mistaken.
To be on the safe side, ask for vehicle records and see if it's been done yet. If not, that might be a bargaining chip. Can't remember exactly what it cost us, but it was at least an hour or two of labor, plus at least a $50 part I think.
