Dana 30 Hydra-Lock for Volvo Rear Axles

I'm unclear about how this nut AynRand has to do with what looks to be a promising limited slip device for our Volvo rear....

Sooooo what would need to be done with axles to make it work?

Is this an opportunity to have stronger axles made?

I have broken more Volvo axles in the splines at the carrier then I care to count.

I would welcome the opportunity to reduce unsprung weight by swapping a Volvo axle back into the car that would take the power my turbo six makes.

Even with the Aluminum center section the 9" thing with the 35 spline axles is very heavy.

Nobody want's to hear about your heavy 35 spline 9" thing..

It bolts into a stock Volvo housing so the only real modification is to re-spline one of the stock axles shorter and get another one made longer. Al wants to go cheap so we're going to have Moser do the cheapie respline on axles we supply.

Yup, Moser will make a set of new alloy axles for $315 per pair. Or you can have Mark Williams make you a set of gun-drilled 4340 ones Mr. Overkill.

You can check the axle shaft sizing on their slick little calculator:

And because you might need it:

REPLACEMENT POLICY
Moser Engineering, Inc. will, at its’ sole discretion replace or repair, free of cost, any part found not to be of ordered dimensional specifications, prior to assembly or use of the part.

In addition, Moser Engineering, Inc. will replace their 33, 35, & 40 spline axles for a period of ten (10) years after the original date of purchase if broken at the splined end due to excessive horsepower. However, 33 spline axles that were broken due to excessive horsepower will be replaced at the sole option of Moser Engineering, Inc., with 35 spline axles. In the event that 35 spline axles are broken due to excessive horsepower within ten (10) years of purchase, they will be replaced at the sole option of Moser Engineering, Inc., with 40 spline axles. If 40 spline axles are broken due to excessive horsepower, they will be replaced at the sole option of Moser Engineering, Inc with another set of 40 spline axles, free of charge.

I am tempted to have a set of axles made up and give them a whirl with a welded up open carrier.

Hmmmmmm......

The 9" thing is all new in the center section, which is a disincentive to make a change.

All the more reason to get a lightweight spool. Hey it reduces unsprung weight, right?

Show me a spool for a Dana 30 and the Volvo pervs will line up three deep to buy them.

I can get another hydra-lok for $200. Plus they're not violent on axles like a spool, welded carrier, or detroit locker. I saw some video of the pavement stages doo wops and your car would defiantly turn in a smoother with a hydra-lok

I'll bet there is more weight that could be taken of your 9". Is the ring gear turned down, gun drilled axles, thin wall chromoly tubes with good bracing, trac9 lightweight housing? I'll bet the weights could be made comparable.

Tim

Tim I may well do such things in the future.

Certainly gun-drilling the axles would be a nice thing.

I'm curious as to how the Hydra-Lock diff would handle.

Something I do like about a spool or welded diff is that it is very consistent.

our friend up here RAINBOW LARRY google: rainbow auto service
has all the stock axles i'll ever need for the back of my corolla.
and all the 240 shells john could want,
and even two merkurs. (4 if you count the sierras)

having a limited slip in the corolla was nice, very.
john L. is right about the spool thing.
but i'm interested in the hydra-lock. i've got five on it. 700 max to bolt into a dana30 rear with the 5.3gear on it. and you say $350 for my pair of spare axles?

he sold me an entire rear end for $150.

Hey Adam,

The $350 is for a pair of new Moser "alloy" axles. We're just going to have them re-spline some stock ones. Last time I checked they will re-spline an axle for $40 each. So $20(junkyard 744 axle)+$80(re-spline)+$200(hydra-lok)=$300 which is still way less than just buying a new Dana 30 power-lock which will split a cross shaft.

Tim

i bet they would make them up so i could run my 14" toyota wheels too! 4x113? hub-centric?

Sign me up. ( do all the work for me! )
