Axle Shafts. Which will fit my 740?

maxitoman007 · 03-24-2020, 03:25 PM

I have an 87 740 turbo with a welded open diff. I'm wondering which donor Volvos will have compatible axle shafts so I can stock up. I have a feeling they are going to be the new weakest link on my car. I'm thinking any non-G80 740/940 would work? is that correct?

G80 would work as well.

I was under the impression G80 cars had shorter axle shafts. Guess not? so that means any 740/940? I know 240s had several different types over the years but 7/9s only stuck to one?

On some early 240's (not sure about 740) you need to trim one axle shaft a trivial amount to fit a G80 in, but on later 240's and (again not sure of exact years) a G80 fits straight in. I put a G80 in my 93 240's rear axle without touching anything. They just made all the axle shafts a little shorter so installing G80 didn't involve a shaft swap as well.

It makes sense then that all 7/9s would be similar as they came out later than 240s.

Yes the 740 940's with g80's have shorter axles. It isn't much. Probabbly work fine. I'll go look how much shorter and post back.

Sounds good thanks.

Max, I have a prepared G80 in my shop if you want it. Originally came from a 740.

Appreciate the offer however I’m just looking to get some axle shaft spares right now. Not a new diff but thanks.
