What would be the cheapest route for a driveshaft? My truck is shortwheel base, and the sm420 has no slip yoke on the transmission.

I am in Fredericksburg and in the trucking business. I have drive shafts made at Drive shafts Unlimited in San Antonio and have used them for years. They are at 105 S. WW White. (210) 333 5050. After you install the transmission, measure from center of the bearing cap on the transmission to the center of the bearing cap on the rear yoke. If you have access to the drive shaft, you can reuse the slip joint if it's still good. If you have the old shaft, shortening it will be very inexpensive. | | | | | Joined: Nov 2008 Posts: 36 Apprentice | | Apprentice Joined: Nov 2008 Posts: 36 | The truck I am pulling it off of has a carrier bearing setup and is longwheel base, so could this still be an option? I have been to Driveshafts Unlimited many times and they do great work, just wasn't sure about the money.

However if the slip joint is in the center bearing, you will need a slip joint. However, there is nothing wrong with using a center bearing. The shorter the shafts, the stronger and least vibration. You might want to use the front half and shorten the back half. You will of course have to have a cross member. I would install the transmission, measure from center to center, and pack up the drive shaft you have and ask Charlie at Driveshafts Unlimited for his suggestion. | | | | | Joined: Nov 2008 Posts: 36 Apprentice | | Apprentice Joined: Nov 2008 Posts: 36 |
