Are Volvo differentials Dana 30s? Will the parts interchange? I have a 1986 Volvo 740 Turbo.

Thanks,
Clayton

Hi Clayton, your 740TI will have a Dana 31, what are you looking for?
Some parts from a Dana 30/31 are interchangeable but ...

Although Jeep does use a Dana 30 on their front axle the carrier is mounted on the opposite side.

If you are looking for a different ratio there is some variety in looking at different models of the 700 series. Limited slips are available through TruTrac.

Jeep does use a Dane 30 in many of their front differentials, but the front application has a reversed ring gear because the front differential runs exactly opposite the rear diff. This means that gear sets from Jeep front differentials will not work in your Volvo.

The difference between the 240's Dana 30 and the 700 series Dana 31 is the 30 series uses a 7.2" ring gear while the 31 uses a 7.562". This small increase in diameter of the ring gear and the larger pinion gear (1.376" vs 1.406") adds up to a marked increase in strength.

Hope this helps

Old post but this came up on the jeep side of the automotive world.

It's the same deal, D30s appeared in Grand Cherokees, Cherokees, YJs, TJs.. all front ends. If your rear D30 is a low pinion (ring gear on drivers side) which it likely is being a car you'll want to find reverse cut D30s on jeeps, IE high pinion. This was found on Cherokees and some TJs..not sure about the rest.

Gear ratios can be had from 3.07, 3.55, 3.73, 4.10 and 4.56 in rare old models. I have never done a swap personally but from what i've read it appears doable
