Hello all,

It's been a long while but I need some input! I've finally had enough of breaking powr lok lsd's in my 67 amazon wagon and would like to install an oem open diff that the car originally came with. The differential in my wagon is a Dana 30 with the 10 spline axles. I have a kind gentleman here that has a complete Dana 30 from a 67 amazon sedan.
Finally, my question is, can I use the internals from the sedan and install into my wagon differential? looking through old Volvo parts manuals, the carriers are different part numbers.

Thanks for the help everyone,

Klaus

Easiest fix is of course to swap in another complete 220 axle. An Amazon saloon one can be used if you convert it to Wagon style tabs for the suspension arms. There used to be a kit available to do that. I've never heard of a Wagon using a limited slip diff. I have a Wagon too here in the UK. Unless you drive in adverse conditions regularly where you need the added traction I don't see the need for it. Easier to put some Mud & Snows on the rear when needed, or studded tyres if that is legal where you are. Converting the Wagon axle to a 4.10 ratio has always been a problem but adding overdrive is good and gives you the same gears as the 123GT, for example, or any other Amazon with OD as standard.

Hello,

As long as everything inside the donor rear end is stock, you'll be able to transfer the necessary parts to remove the PowerLok.

The majority of Dana 30 differentials installed in 122S sedans or coupes came with 4:10 gear ratio ring and pinions while stock P220 Dana 30 rear ends came with 4:56 gears, so you'll have to transfer the ring gear from your posi. If you opt to install the 4:10, you'll probably have to adjust the ring and pinion and that's not easy.

May I assume you're breaking the crossshafts in the PowerLok? New ones are available and I'm pretty they're made of stronger material. However, clutch kits seem to be hard to find nowadays.

FYI, we're about to rebuild a Dana 27 for a customer and for the 1st time, we're installing a Quaife posi. Quaife also makes posis for Dana 30 rear ends with coarse spline axles.

Hi Eric,

Thank you for the info, I did buy the rear end to see and now that it's dismantled I can see that it will work just fine.
Yes, you are right! I kept breaking those flimsy crosshafts and had enough although I really enjoyed driving the wagon with the LSD. After 2 trys at it, I can't put more money into the differential anymore, lol.
I hope the diff you are building is a hit and thanks again for the reply,


Klaus
