front drive shaft u joint size? 1330?

[Tike]

ford parts has it as a 1330 size but rock auto says its 1310 size? can someone tell me the right part for the front u joint? and what size straps i need.

doing the front pinion seal but one of the Torx 30 bolts stripped so i am prepping for the worst case of needing cut the head off the bolt or whatever i need to get the **** out.

When I replaced the front u-joint and straps, I used those on my 06 v8.

They came with 8 mm bolts, not the stupid torx.

1310 u joint! thank you for verifying.yea i striped the one ****ing torx bolt and the straps make it impossible to fit a socket it on it. im hoping i can use a box end wrench and back it out enough to then fit a socket on it. or just hammer in a T35 torx.... worst case cut the strap off then vice grip.

my pinion seal is bad and im guessing its that 170k and the OEM u joint thats looks toasted.

Interesting how the seals hold.
My 06 still rides on original front pumpkin with 301k and nothing leaks, nothing was replaced.
My 2012 f150 with 108k miles needs new seal on rear axle.
Go figure.

seals are usually a symptom not the cause. so my u joint is likely causing vibration that damaged the seal
