1940-1948 Torque tube interchange
Are the torque tubes the same length on 40-48 Ford cars? I know the radius rods are longer prewar but I believe the tube is the same length but I can be wrong.

Re: 1940-1948 Torque tube interchange
The BIG GREEN BOOK on page 131 shows part number part # 6A 4504 Tube assy (torque)-with bearing.cup and grease retainer, passenger 1941-48.
There is no spline count given for this listing. It also shows 68-4504 Tube Assy. (Torque) with bearing cup and grease retainer - used with 6 spline pinion, Pass, Comm, 1937-41. It is not clear to me the actual difference between these two part number listings. Last edited by 19Fordy; 05-15-2020 at 12:03 PM. |

Hey Stud....I have it noted that a '39-'40 torque tube is 70" long, and that the '41-'48 tube is 72" in length. Can anyone verify, please? DD |

"4504" is Ford language for a TORQUE TUBE. Without the GREEN BOOK in front of me, I'd be inclined to guess that the "68-4504 Tube Assy." listing is actually "68A-4504", the "A" signifying Pass & Comm. The "68" indicates 1936 as the first year for this application, which applied to production years 1936 thru 1940 LENGTHWISE, even though the '38-'40 tubes were subsequently fitted for center bearings. The "6A-4504" indicates a Pass & Comm torque tube with 1946 being the first year of application. As I wrote in the other post, I have a personal note to myself that '41 t-tube was 2" longer than the '40 and earlier. 1941 Fords had an awful lot of strangely dimensioned, one-off suspension components front AND rear, so....I ain't certain about that '41 length! Guaranteed though, the '40 is different in length than the '42 thru '48 t-tube, as the wheelbase increased in '41 over the '40 models! DD Last edited by V8COOPMAN; 05-15-2020 at 01:14 PM. |

Re: 1940-1948 Torque tube interchange
Thanks all, that sounds correct. I just measured two at 72" and I know they are postwar. Makes sense that the '40 would be shorter.

I measured a '41 tube at 72" in a thread dated 2/12/19.
