When did Ford begin utilizing a greasable driveshaft carrier bearing in the torque tube? I understand that in 1937 they started using a solid driveshaft.

I think it was 1938.

From the Early V-8 Club's 1937 book,

"There were two designs of torque tubes and drive shafts used in 1937. The torque tube, 48-4504 used in early production was carried over from 1935 and was used with a pinion having ten splines. The torque tub, 68-4504, used in later production was used with a pinion having six splines. The drive shaft 48-4605-A used in early production was a tubular shaft. The drive shaft 68-4505-B in the later tube was a solid shaft supported in the middle with a roller bearing, 78-4658. A lubrication fitting was present on the later torque tube."

Thanks for the information. I have the 1937 book. I'm not near it currently and I figured Fordbarn would come through.

I'm planning a rebuild on a '37 rearend. The torque tube that is in the car currently, does not have a grease zerk for a carrier bearing. That led me to belive I might have the early style drive shaft.

Seth, I have a 1937 coupe with q motor number built in the first half of February, 1937 and it does have the grease fitting in the drive shaft. I kinda wish I had the one without the fitting so I didn’t have to worry about that bearing.

Zeke,

I'll read the '37 Ford book when I get home tonight. I'm wondering if I have a solid, 6 spline driveshaft without the bearing or is it a hollow drive shaft and 10 splines?

I want to go with a 3.25 rear end gear and that of course will be a 6 spline pinion shaft.

Zeke got it right. I read the 1937 Ford book when I got home. It was just as he stated in his post.

Thanks to everyone for the help.

There are some good threads on here about the stabilizer bearing replacement showing the home made tools. Skip Haney's replacement is available. This link has skip's instruction sheet:
