Which U-Joint

[Big Secz 26]

When I pulled the engine and trans this past weekend my rear U-Joint fell apart. I was looking online and see that there are a couple different kinds, which one would I need? I see they have some that are 3.219" or 3.622" and some have two sets of retainers and some have four.

I believe its a 1310 u joint?

Should be a 1310 unless you've got a center section from a late model van or truck. 1310 should measure 3 7/32" wide with a cap diameter of 1 1/16".

Get the solid u-joint. Not the one with the hole drilled down the center for grease. Solid ones are much stronger.

Bring your old one into the parts store, as well as the cap fasteners. You don't have to mail order u-joints.

If you want the solid U-joints, the corner parts store may not have them. I got mine from a driveline shop.

Autozone actually sells solid, non-greasable 1310 u-joints.

Good to know! Unfortunately I use 1350 series and I doubt they'll have those.

When I searched on Autozone's site it didn't give me the option of a 1310 u-joint. This is what it what I get.

I bought Lakewood Performance Universal Joints from Summit a couple weeks ago. I can't say how well they perform or anything yet though as I'm still piecing the car back together.

A mild 302 shouldn't tax the u-joint too heavily.

[Big Secz 26]

Yeah I'm not going radical with the motor just over 300hp. I'm just confused by the different types that show up on Autozone's website. I would go in the store and ask if I had in confidence that the idiots that work at my local store knew what they were talking about. I went in there Saturday and asked for an engine lift chain and they didn't know what it was.

Just go in and ask for a ujoint for your make and model car, and tell them the engine size, they should ask if you want greasable or non greasable, tell them you want the Brute Force Brand for your car, its a non greasable ujoint...Ie has no hole through it, simply pack the caps with grease and install it....They are good U-joints, I have them in my 77TA with over 100 passes on in with slicks...car weighs 4000lbs pulls a 1.74 60', makes 500lbft of torque and has never had a ujoint problem, has several N2o passes on it as well just blowing the tires off...So i think these ujoints will be fine for you.

Actually they do. You have to use the 2004 Mustang Cobra u-joints for them to look up. Their Duralast Gold are the solid non-greasable ones. I've never used them, so I don't know how good they are.

 

 

I second the notion to go into the store and get the Brute Force ones. I used them on my car before swapping in the larger driveshaft and T56. They will be able to hook you up. You want the 3.219" ones, as they are 1310s. The 3.625" are the 1350s used in CJ cars IIRC.

 

If you order online, pay attention to the u-joint size because Ford uses a special u-joint for the rear one. The caps that attach to the rear end are smaller diameter than a standard 1310. It's called a 1310 special IIRC. See here for measurements: http://www.actionmachineinc.com/ujointmeasuringguide.aspx
