MK1's and the ACN - AON - ASF - ACL 020 VW Trans

[R.O.R-2.0]

thanks - read thread -
Whats saying that since the 100mm shafts are a bit shorter - how much I know not but the concept is this - that one could put 90mm joints on 100mm shafts to come up with enough clearance to install an 80% shim kit thereon and use with 90mm flanges - so actually maybe the 90mm flanges with 80% shim kits would work best if hooked onto 100mm CV shafts with 90mm joints installed thereon??? Does anyone know the difference in length between the 90 and 100mm CV axle shafts???

the 100mm trans diff is about an inch wider, side to side..

so, i imagine the difference in the axles would be about a half inch on each side..

90mm CV joints dont fit right on 100mm axles..

they are way sloppy.. the 100mm units are THICKER..

so, even if you get the 90mm CV on there, there is still going to be axle stub sticking out of it.

100mm and 90mm CVs are not the same. the spline count and diameter are the same, but the 100mm unit is quite a bit thicker..

Brother and I are making well over 150 ft.lbs of torque on our 1.9L's, his is probably closer to 180.. damn that thing has neck break torque. Squats the ass end down and takes offf.

Basically what I am trying to say is, we are both on 90mm axles.. They are not the weak spot, and will not fail.

....until they fail.

I'd be worried about the 020 over the axles lol. How many horror stories you hear about breaking axles?

[Dakotakid]

Yeah. I've honestly gone over a million miles on 90 mm cv's. I tend to pamper stuff though.

Best to stay away from the bargain-bonanza-o-matic cv's that a lot of these guys buy because they don't want to soil their fingers salvaging and prepping some good originals.

It is why I bought the lifetime axles!!

I think the 90mm might be stronger than 100mm bigger outer circle torquing on same size inner shaft.

Ok so great - my question is does anyone know of anyone that has used the 80% Peloquin shim kit on 90mm Mk1 axles with no problems after haveing ground down the CV axles stub ends? This is going into a Mk1 Pickup and I communicated with Brian at BrokeVW - he said that all he knew is that the 80% shim kits will at least work with the 100mm axles but not for sure on the 90s??? If grinding down ends on 90s solves Mk2 - ACN flanges from being hit and or torqued by Mk1 shafts then that is what I will use - Mk1 90mm CV axles hooking up to Mk2 ACN trans - other wise will need to go for the 100s - thanks for input!

I'm going to install an 80 kit Wednesday grind down my 90mm ill measure it and post what I find out. searching the vortex might yield some more info.

mk2 is wider than a mk1.. but the passenger side axle is a tad longer. drivers side axle is same.

i doubt there is enough room to grind the axle stubs down enough, and stilll get the c-clip back on the axle.

Never said he was using mk2 axles lol.

i never did either.. just stating that mk2s are wider, and the axles dnot make up the whole difference..

the mk2 trans is WIDER than the mk1 trans as well..

the distance from flange to flange is like +1/2"

thank you ROR-20 - info from those who have been there and done that is better than Bentley - thanks again!

[8v-of-fury]

I have an mk2 ACN in my mk1, why would the trans be a different size?

[SR Heer]

since the 100mm flanges are of different configuration in depth or heigth compared to the 90s it stands to reason that measuring from outer edge of one flange to the other might not be the same length which comes into play when getting correct size CV axles - did you use Mk1 CV axles? do you have the 100mm flanged ACN or the 90mm - I was thinking of getting the 100mm because I wanted to install the 80% shim kit so was thinking of going 100mm flanged ACN but was not sure just what CV axles to use in Mk1 with Mk2 tranny - but if the 80% shim kit works fine with the 90mm flanged ACN after grinding of end of CV axle then that is the way to go! What do you think?
