2021 C4 of the Year - Unmodified Finalist
Default Torx 45 or 55

I'm about to under take replacing half shaft u joints and the Teflon washer behind the bearing ***'y.

The FSM says the three torx head bolts are T45 but the posts I see here say they are T55.

Can anyone offer spiritual guidance on this before I get in there? I bought a 6" T55 x 1/2 drive, but I can exchange it if I have to.

Also any link to the BEST sticky or post for doing this would be appreciated.

Thanks.

The ones on my 96' are T-55 if you are referring to the three rear hub bolts.

Model year would help as the bolts seem to vary by year.

As soon as you get under there you will know for sure what size it is......One suggestion, don't try to use cheap sockets.. Buy a good set of sockets like Craftsman or SK that include the T45 snd the T55, then your covered no matter what size it is. Also, the night before doing the job, soak the bolts with PB Blaster or one of the other solvents to make the job easier.........WW
