From the All Pro Site:

One set is the standard '84 and later Toyota U-Joint pattern (2.350" X 2.350"), the other is '84 and later CV joint pattern (2.350" X 2.775").

Does anyone know the 83 and early bolt patterns? I know they are the smaller bolts.

 

[JamisonWorkshop]

same pattern, smaller bolts. 12mm i believe

Will a front CV driveshaft out of a 79-83 pickup have the same flange pattern as a 85 rear transfer case and 3rd member???

I'm working on a project right, now so I will be confirming these myself soon. Does anyone have any of these laying around where they can be re-measured. The dimensions should all be even metric numbers like (56mm) or (64mm) and not stuff like 55.9mm or 64.1mm.

Here is the compiled list so far from this post. Once this info in comfirmed I will add it to the Toyota FAQ.



Toyota Bolt pattern listing:

U-Joint pattern '79 thru '83 (maybe early '84)
3.340"[84.8mm] Bolt Cirlce
2.200"[55.9mm] x 2.525"[64.1mm] Rectangular pattern
(4) holes .335"[8.5mm] Diameter


CV-Joint pattern '79 thru '83 (maybe early '84)
3.575"[90.8mm] Bolt Cirlce
2.350"[59.7mm] x 2.670"[67.8mm] Rectangular pattern
(4) holes .335"[8.5mm] Diameter


U-Joint pattern '84 and later
3.323"[84.4mm] Bolt Circle
2.350"[59.7mm] x 2.350"[59.7mm] Square pattern
(4) holes .413"[10.5mm] Diameter


CV-joint pattern '84 and later
3.636"[92.4mm] Bolt Cirlce
2.350"[59.7mm] x 2.775"[70.5mm] Rectangular pattern
(4) holes .413"[10.5mm] Diameter



Oh and do Tacos have these patterns? If not what year is the first taco? 95-96????

One thing is my 83' donor case had a square flange on front, not round but it was the larger cv bolt pattern with smaller holes. One way to tell what year case you got. My 94 is round front. I have probably 6 of them I can line up and try to measure thursday. See what I can come up with.

There are several variations out there. There are at least 3 different '84-up CV bolt patterns out there that I've run across, and I wouldn't be surprised if there were more (IFS, V6, auto, rear 2-piece CV, etc.). They are all very similar though.

I just clamp the one I need on the flange, and drill. Leave room for a couple of extra patterns on there.

HAS ANYONE ELSE CONFIRMED THE #'S
