My Haynes Resto manual makes reference to a "splined tool" being the correct tool to remove driveshafts. What is it?? I have never heard of one before and those that I have asked have no idea either.

The book also says that I should NOT use a hex key as I may wear the splines on the inside of the bolts, as the tool won't fit correctly.

So to you guys that have removed CV's before.... do you guys use "splined tools" or if not...what do you use?

i stead of being a hex its more like a star i think 12 point from memory, i use this splined tool but i can remember the size

i think its a torx head bit ~8mm
get the right tool or replace with allen head bolts

It's a triple-square spline, I have a stahlwille with the size M8, Snap-on also list it as a M8. I think the correct name is XZN

Hazet XZN-8

Bingo. Triple square or twelve spline are the names I had used when selling tools. It was usually Stahwille brand that was supplied, and that I would trust with a high torque application like that.

Excellent!!

Thanks heaps guys

..great to have so much knowledge in one place.

Take a sample bolt with you, mine is XZN-8 in Dowidat brand.

A 6mm AF allen key will do the job,but the correct tool will help prevent it chewing out.

Make sure you clean out all the gunk from inside the recess, or even the 12 point one wil 'skip' out.

If the hole has been butchered, an good 'vise grip' on the head may get you out of trouble.

i've always called them multi splines sockets
make sure you pick the dirt & muck out of the bolt heads with a small screwdriver(even better if you can squirt some compressed air in there, watch your eyes!),then give the socket a tap with the hammer to make sure it's fully inserted.
best not to jerk your ratchet,better to use a smooth even action when undoing.
if you accidently round it off,tighten the two surrounding bolts and use vice grips or a large cold chisel and hammer to undo(watch them knuckles!)

wouldn't mind a dollar for every one of them suckers i've undone!

Hi,
Something else. Mine is a "bit" from a Minimax kit. You may be able to buy this 8mm trisquare "bit" seperately, either Minimax or whatever. All you need then is the appropriate driver (3/8 in my case) socket.

make sure that your CV bolts still have the splined heads - have you stuck your head under the car?

That tools is damn expensive and isnt used anywhere else so i'd get the old bolts off with an Allen head (24 of them - this took me 3 days once, dont ask!), then swop them for normal Allen head versions of correct quality.

If yuo cut the heads off with an angle grinder the shafts will just come off
