Depends on your gearbox ratios and tire size.

saginaw 4 speed in a vega. Built 2.3, too much top speed for my lack of fear at age 20.

^China metal/pinion probably won't last compared to a 1031, but "yes" basically of the stock volvo axles.
Volvo doesn't use the 3.54- carrier either/makes up the difference with the ring gear, have fun with that.
Yes, and probably. But 7/9 series axle housings do not bolt up in a 240.Will a TrueTrac 3.73 fit both a 1030 and 1031 ring gears? Will a 1031 fit my 1030 equipped car?
Jeep Dana 30 gearsets will only fit a 1030 diff. 1031 gearsets are available, but they're $600-800 plus shipping from Europe.
The Dana-Spicer gearsets are made in India, and have worked very well for us in race cars. The USA Standard Gear and Yukon gear sets are.. made in the USA. I had a USA gearset go soft in a race car, no 1000 mile break in. So I can't really fault it. The Dana-Spicer gearsets got even less of a break in and were completely fine.
Yes, and probably. But 7/9 series axle housings do not bolt up in a 240.
No, the later 240 rear axles are 1031. I don't know when the change over occurs. It is probably around 1985 when the rear axle had the tone ring added to the carrier.
I have a 1981 with a 1030/3.73 and a mechanical speedo cable.
Both a 1030 and a 1031 will accept a TrueTrac, and my mechanical speedo cable will hook-up no problem to a 1031?
No to these statements. Both are incorrect.
"For clarification... there are no 240s with a 3.31 gear set in a 1031 axel? As far as I know the 3.31 gears were only available on older 240s with a 1030."
Somewhere around 1985 Volvo went to the 1031 axle in a 240. All US market manual trans equipped 240s run a 3.31 ring and pinion set from 1983-1993. The nice thing about running a 1031 is that the 1041 gear sets fit it.
If you don?t want to cut the axle, get a right side abs axle- fits fine with 1031/G80
Sounds about right.No, the later 240 rear axles are 1031. I don't know when the change over occurs. It is probably around 1985 when the rear axle had the tone ring added to the carrier.
