I found a good deal on a new aluminum DSS drive shaft a few months back. I thought about going with steel, but the price difference between a new steel one-piece DSS drive shaft shipped and the deal I got on the aluminum one made it worth the extra few coins to get the AL one.
The 240 had a vibration between 55-75mph in 5th gear and with no real driveline shops within 1 hour of me and the ones I did find had the same work hours as I did. I decided that fixing the current driveshaft wasn't worth the hassle.
Pulled the old (heavy) driveshaft out. The diff side is held by 4 bolt/nuts combo and the front the driveshaft just slides into the tranny. Do be warned that when you pull the driveshaft out of the tranny... fluid does follow :squint:
Reversed the steps for the nice and light AL one
.
The only item that I was a little concerned about was the amount of shaft hanging out of the tranny side... I did a quick search on FA.com and it seems that this is normal, one inch roughly of the shaft is showing.
I won't be able to see if the vibration is gone till later this weekend. The car will stay on jackstands until I get the JWT S3 cams in, the HKS exhaust installed, and an idle problem resolved.
