What size U-joint will be on the pinion side of a 79 Bronco? Is it a 1310?

 

[Aggro]

I do believe so.

 

[Dan-H]

I think so too.

 

[welndmn]

hmm not to sure, but i thought the big bronco used a little bigger one like a 1320 or something

 

[broncoboy]

its bigger then 1310 i thought. its wider. the cross is bigger
pat

 

[yldkat]

Are the crosses equal in length?
The 1330 is basicly 1 ton width (1350) with 1/2 ton size caps (1310)

78's used a 1310 at the pinion, 79's went to 1330 series. Many times these vehicles have had swaps done over the years. With so many options for the 9" it's very iffy to guess at which U-joint IS in there, I can tell you which one should be there, and if you give me the needed specs I can tell you what spicer joint would replace it.

my '79 had 1310 at the pinion and 1330 at the tcase, and 1330 both sides on the front.

Keeping in mind I am only stating what was on the books as specified for a particular year, and drive line combo and that mother Ford has a reputation of instaling what ever is at hand and who knows what has been swaped on a vehicle you bought used.

1978 Broncos came with one of three different rear drive shafts depending on drive train 1310 series on both ends unless equiped with the 400 eng, then it was 1310/1330

1979 Broncos came with one of three different rear drive shafts depending on drive train but all used 1330 series joints at both ends EXCEPT when equiped with a 351M/auto trans/NP205, then it was 1310/1330 5-153x (1310) at the pinion and 2ea 5-278x (1330)at the TC.

I fully admit this is all book data, and what is under your bronco may differ, but for what it is worth there it is.
