Greetings everyone, just but a 91 240 to go along with my 93 940. Has a few issues one serious one is the rubber ring surrounding the carrier bearing on the driveshaft is bad,the spring is out of it. The loop that holds the ring in has two bolts that attach to the underside of the car. Now the fact of the car being over 20 years old and in New York State,my question is how subsectical are those bolts/holes to stripping ? Just want to know if I'm getting into a potential can of worms when I drop the driveshaft and rubber ring out of there. I have researched the archives and the job looks straight forward, once you drop it and separate it.
