Which drive shafts ?

Due to head gaskets continually blowing, in 2017 I changed my Mk1 Caddy 1.6 D engine and gearbox for an AAZ Mk3 Golf 1.9 TD.

Initially it went like a dream, actually keeping up with the traffic !

Now the drive shaft on the passenger side is making a bad knocking noise and the cv joint fell apart. The local gearbox guy who had a look to identify the noise said the angle from gearbox to wheel was 'quite acute'?

I know many others have done this conversion. Can anyone advise me whether to get a new Mk1 drive shaft or a Mk3? Everything else on the Caddy apart from engine and gearbox is Mk1.

Thanks.

What year of Caddy, and what is the axle size of your aaz

The typical older mk1 had 90mm axles where as the 87-93 Cabriolets had 100mm. axles.

The 90mm axles when transmissions were swapped would fit into the 100 spindles on latter cabbies, where as the 100mm axles wouldn't fit into a 90mm spindle with out Grindage.

So the axle sizes have a lot of determing things, as I suspect that the AAZ axles ae either older stock or newer stock with older styles of CV's attached.   

I thing some more investigation is warranted as to which axle you are currently trying to replace.

A mk3, or a 100mm Cabriolet, or a early 90mm Golf?

Thanks for replying.

The AAZ was from P reg 1998 Golf TD estate.

I don't think they changed drive shafts ( wasn't detailed on the invoice). As I said, nothing else was changed so I assume they just put my Mk1 shafts into the Mk3 gearbox?

I just wondered, as I had read somewhere that cv joints and shafts are known to wear after these conversions - whether I ought to get another Mk1 shaft or if it would be better to get Mk3? But whether that would then fit at the wheel…?

Meant to say that my Caddy is 1990.
