A trying to install the driveshaft into my roadster’s T5. Is the thick rubber plug around the T5 shaft supposed to stay in with the shaft in place or is it a protective boot for shipping purposes? It is separate from what appears to be a dust shield around it. If it stays it looks like it would bind to the driveshaft in short order and tear things up. I don’t see how the shaft is supposed to slip in with it there, but don’t want to pull it out if it’s supposed to stay. Thanks.
When manufactured, they were installed to seal up any leaking during assembly/transit to the engines. Once in a vehicle, they were simply pressed in by the driveshaft yoke. Less time taken and no harm done. That's why you see them in almost every teardown. They do no harm left in. However, if you can remove it, I'd remove it. I never put them back when rebuilding.
