Hi Everyone,

 

I've been replacing the cv axle boots on my brother's mk2 fabia and everything has been going relatively smoothly however I realised in the haynes manual it states you should make an alignment mark where the cv shaft bolts to the gearbox output shaft. I forgot to do this and would like to know, how critical is it that the cv shaft bolts up with exactly  the same orientation?

 

Thanks in advance.

It isn't critical.

Great, thanks for letting me know, this is the first time I have removed a cv shaft and was worried that I had made a serious error.

Thanks again for the advice but I have one last question, do you have to replace the bolts which attach the inner cv joint to the gearbox output shaft?

Skoda workshop manual will say replace, and it's certainly best practice, but you'll probably be OK reusing if none are damaged. What torque plus angle numbers are you going by?

It's not critical, unless they are stretch bolts for some reason.

I don't have the equivalent document for mk2, but for mk1 Fabia there are two different types of bolt used M8 or M10 depending on engine I think. Each has its own tightening info:

2 - Screw

❑ replace after each removal

❑ initially tighten to 10 Nm, subsequently tighten crosswise to final torque:

M10 screw: 50 Nm + 45°

M8 screw: 20 Nm + 180°

 

There are more variations still if the car has the 'tripod' design inner CV, not sure which engines/gearboxes use those?

 

Have you already refitted these screws, or not?  What size thread are they?

 

this is for Mk2

 

 

Hi everyone, thanks for all the advice and information, my car uses the m8 bolts, I have just bought a new set as I figure it's not worth the risk over £17, especially since the car often driven in a 'spirited' manner.
