Some ALH engines have different harmonic balancer and different torque
If you search for this part number N-103-036-03 you should find a posting by me explaining why on my 2003 ALH engine (and some others) the torque spec for the Harmonic balancer bolts is :
10 Nm + 90 degrees turn
Always replace!
VW dealers do not know this ( mine didn't)

Thanks for tracking this one down... BTW: your other posting is in the A3 forum... you should really have it moved...
10 nm ??? That's not very much... 7.3756 ft*lb... even with the addtional 90 degrees...
We replaced my timing belt yesterday, and although I had replacement bolts, we re-used the originals... Since they weren't replaced during the first timing belt replacement either, I think one of these days I'll just replace them on principle... (They looked great, BTW...)

Thanks!
I did a search for "Harmonic Balancer bolt" and blindly posted that without noticing I was in the wrong Forum... Thanks for pointing that out! I think I fixed it now.
btw, 10 Nm + 90 degrees is a lot of tension, I can assure you because I just did this on my car. I was worried I would round out the hex keys. Try it and you will see ; )

The PDF says 33 ft*lbs - but that's not really enough... According to Kerma, "screw down the nozzle retaining nut with a wrench until it bottoms out on the injector and is "snug". Then take a deepwell socket and breaker bar and tighten it 30 degrees."
The injector hold-downs are only 15 Ft*Lbs...

Do you have a Bentley service manual??? Be careful not to have any weight on the wheel when you start loosening the front axle retaining nut !!!!!!
To install:
Tighten 12-point nut to 200 Nm and loosen 1/2 turn.
Turn wheel hub 180 ° .
Tighten again with:
50 Nm + 60 ° additional turn (make marks... 2 "corners" of the nut equal 60 °)
It also says to "Coat with oil before installing the axle shaft:
The splines of the outer joint
The thread of the outer joint
Wheel hub splines
The contact surface and threads of the 12 point nut."
(BTW: for those that have cars with a bolt instead of the 12 point nut: NO OIL on the threads of the bolt !!!!)

And how about the rear axle nut for '04 Jetta? (The big 30 mm 12 point nut).
TIA!

According to Bentley, it's done in 2 stages... first tighten them diagonally to 10 NM (7.4 Ft*Lbs), then tighten them diagonally to 40 NM (29.5 Ft*Lbs) (that is: if those are 8 mm bolts... the 10 mm bolt cars are tightened to 70 NM)

What about the use of anti-seize and locktite? Are there locations either one of these products are required or banned?
