Here's a picture of the universal joint that currently fits my driveshaft and Ford 9" yoke. Since I bought another third member for the rear axle, it came with a wider yoke. I was wondering if they made a u-joint like the one above except with two of the facing needle bearing caps wider than the other two. This way I won't have to get a larger driveshaft (2.5" original, 3" to match rear yoke) Like this: Anybody know if something like this exists?
Yes they do. It's called a conversion joint. I'm using one in the A.M.X. right now. Wish I had a part number for you. If you have a drive line service shop in town go talk to them. It's a normal ****er item. Parts house will want to know Make Model and year unless the Person behind the counter is real Savvy. The Wizzard
What he said, find a clutch and driveline shop they do this all day. You go to NAPA and they will spend an hour on the computer and you will probably get the wrong one.
If the pinion shaft is the same spline, there were two different ones I think. You can just swap the Yokes from your old third member.
Yes but I've been told that you cannot simply swap the yokes without screwing up all the shims and adjustments in the differential or something like that. I don't want to mess with it by taking it apart.
Are the caps all the same diameter (1 1/16")? If so, then it should be a 1310-1330 conversion joint, which is ****er # 5-134x.
.....yes, but not exactly. They'll interchange but the pinion bearing preload will need to be set-up correctly with a fresh crush sleeve, probably a seal, etc, etc, etc. The only exception is if the pinion was converted from a crush sleeve to a solid spacer/shims by somebody in the past. -Bigchief.
Go to any parts house and ask for a "Big Little U joint". even the guys @ the advanced auto stores know what your talking about
Call Coleman Machine in Menominee Mi. Circle track guys have mixed up **** like this all the time. they have good stuff and the price is right>>>>.
One more thing to watch for. Ford p***enger cars after about '62 and pickups '80 and later use u-joint caps at the pinnion yoke that are 1 1/8" diameter. The u-bolts also have a wider spread. If those larger caps are needed, you'll also need to buy another u-joint to make what you need. ****er 5-1204x has the same bearing journal dimensions with a pair of the larger 1 1/8" caps. It's vehicle application is like for the rear on a '78 LTD or '80 and up pickup.
The conversion u-joints are in stock at any good auto parts store(CarQuest, O'Reilly's, NAPA, and most independents). Hotrodders and racers and farmers and such have been using them for decades. There is a section of the printed catalog(yes, they should still have one of these) which cross-references the joints by size and part number so you can figure out which one you need.
