Maybe I am confused... I had this problem in my 300ce.... i was certain it was a bearing problem...but when they told me the exhaust had to come out , i went ahead and got the flex discs..... the front was about to break apart... the rear was fine....

that's my experience.... the indy charged 400... plus i gave him the parts....

i thought it was a fair deal...

The U joint is staked in place and requires grinding and restaking to renew. Very hard in field, Some members have replaced it with some ford application U joint but its a very hard job. Best left to a driveline shop that can repair truck shafts.
