drive shaft yoke
Has anyone bought one of Shoebox Central's new driveshaft yoke's ? They show a new one that is for 49-55 Ford and Mercury. I bought one and went to put it on the driveshaft last night and it seems as the U- joint "eyes " are a bit oversize and the cup will just push in with just the pressure of your hands. I was just wondering if anyone else has had this problem, or did I just get a bad one. I have not contacted the vendor yet, I was just wondering if anyone else has had any experience with this part from them. all of the stuff I bought from them in the past has been fine. I will post this on the early v8 forum as well. thank you for any input.-----Jim

Re: drive shaft yoke
There's a good chance that your replacement yoke was designed for a 1310 u-joint, the most common size. If that's the case, you'll have to get a u-joint that is 1310 on the yoke side, and whatever size is required on the driveshaft side. I had to do that when I replaced the pinion yoke on my 55 T-bird, having changed the rear-axle ratio.

Re: drive shaft yoke
There were two front knuckles used. The 8M-4841-A was used prior to the introduction of the Merc-O-Matic. The 1M-4841 was used for the Merc-O-Matic so there is a difference but I don't know what it is. There were also two U-joints, The 8M-7042 and the 1M-7042-A respectively. My big problem now is that I don't know if the MOOG & SKF 507 or the Spicer 253242X are replacements for the standard or the automatic transmission since I don't have much info to go on. The damn things may be interchangeable but I just can't verify that.
A lot depends on if it's for standard or automatic applications. It's been a while since I looked all this stuff up but if my memory serves, the bearing diameter for all 4 caps was 1-inch. I think the 1310 UJ has a 1 & 1/16-inch size bearing cap. The OEM ones use C-ring internal snap rings that fit between the cap & knuckle bore. These will usually hold a push fit as long as it's not a real loose fit. The Ford car book that I have that's up through 1953 only shows the 1M-4841 knuckle & plug since that part number likely replaced the part made prior to 1951 for the Ford cars.
