Lobro joint bolts
Avoneer - 17/1/05 at 10:11 PM

Hi guys,
I'll be replacing those "hard ro remove" ford torx bolt things and replacing them with socket caps. Do I need wahers or sping washers as the Ford ones were buggered and I don't see any advantage of them over spring washers or even none at all.
Thanks,
Pat...

i use "frilly" washers n a dob a locktite, never had one come undone.

Can post you some FOC if you cant find any local.

Sort of on the subject...

Any idea why a lot of manafacturers on their 6-bolt driveshafts link pairs of bolts with a sort of double washer? Can't see the point of it at all, yet they're on every 6-bolt lobro style joint i've had the pleasure of undoing.

10.9 or 12.9 socket caps - more than enough I think???????

John - thanks for theoffor, but I think I have loads of them frilly things - never used them as I always prefered spring washers and thought they looked feeble, but if yours haven't come off......
What bolts did you use?

Cheers,
Pat...

The double (bannana shaped) washers are to spread the load and stop the screws tearing through the tin boot retainer.
Avoneer, make sure you use 12.9 screws and don't use any thread locker or washers other than the double washers. Torque them to 25 lb/ft...no more and no less.
They're critical fasteners and need to be treated as such.

Hmmm, mine are a bit more than that.

Rorty,
How much does it matter? And should I slacken them off now or is it too late?

Cheers,
James

If you haven't driven the car, it may not be too late to retorque them. It largely depends on how much you've over torqued them. They're elastic to a degree and then they take on a permanent set, by which time they're useless.
