Just wondering how much hassle (or even worth it) it would be to upgrade a 8.5" corporate 10 bolt w/ 28-spline rear end to a 30-spline resulting in 30/30 splines for both axle and pinion?

In that case, what Eaton posi unit would be needed, since the 28-spline one below will no longer work?

This is the eaton unit you will need
19559-010

I can get you 30 spline custom Moser axles we do this conversion all the time for the V8 Buick guys and there 10 bolt 8.5 71 72 rear.

What is involved in the 'conversion' process? Welding? Cutting? Are the axles stainless steel outside the housing? They look shiny in the pic. Are the same A9 and 712146 axle bearings/seals used with the Moser axles?

Do any modifications need to be made to the Eaton Posi Unit 19559-010?

Also, in general... is it a waste of time to upgrade from a 28 to a 30 spline axle? For example... is it only worth while if you say have 500+ HP or something?

Thx

EDIT: I guess there is always the thing of 38 year old 28 spline axles, and might be worn/broke or whatever when pulled out.

 

Jim,

Can you give me a price on the 30-spline Moser axles you mentioned, as well as a complete/mega Timken rebuild kit... including LM102949 / LM102911 carrier bearings/race, as well as the A9 and 712146 axle bearings/seals etc. shipped to 14301 (my US mail forwarder).

Thx,
Ken

EDIT: Curious, what about Strange axles... are they any better (or worse) than Moser?

 

The "urban legend" is that Moser is more street friendly than other brands. Mark Williams is probably the strongest race axle but costs about double what Mosers go for.

 

Any Currie, Strange, Moser, MW custom race axle will do more that most cars and or trucks will ever get to the ground on the street and even the track.

It is usually HOT laps that will do in the axles and other metal parts. Over heated metal has a malleable temp that will start the reforming process YOU DO NOT WANT! This is the reason for all the special mixes out there to prevent this from happening.

MAke sure these parts are put in correct that will be the best way to keep them alive.

Wasted of time and or money.

This will all depend on your worries of breakage and power output and USE of your vehicle. Race, street/strip, cruise, burn out contests, etc.

If your old axle bearing press on surfaces are good and the spline are straight...And or you can get the axles on a lathe and have a machinist measure the runout...They should be good to go. IF your car ran fine with out vibration etc. They are probably good and do not even need to check run out issues.

I will send you the prices real quick here. Jim

 

I like the idea of stronger axles even if not really needed. I also like the idea of nice shiny new axles and not having to media blast then paint/powdercoat the originals.

Do you modify the axles at all, or does Moser do it?

 

Swapping to 30-spline axles does NOT require any modifications to the housing.Just get a 30-spline carrier to match,and order the axles with the same specs as your originals,but get them with 30-splines.A pair of 30-spline Mosers,with wheel studs,bearings/seals,& retainers,will be $450.00 with the shipping.
The stock 28-spline axles that are in your housing now are a nice stock piece.However,if you plan on running 11:70's or faster someday,then I would suggest swapping them now,& do everything once.

 

So a total of $450.00 includes all the below?

• 30-spline custom Moser axles
• complete Timken rebuild kit (including A9 and 712146 axle bearings/seals, and LM102949 / LM102911 carrier bearings/race)
• wheel studs/retainers

I am still unclear on the Moser axles... who modifies them? Moser? If they do... you just order from them saying you have a 8.5" corporate rear end and they do the rest? What is the waiting period?

 

You would get 2 new axle shafts,10 wheel studs,bearing retainer plates,a pair of axle seals # 712146,a pair of SET-9 Axle bearings,and the shipping,for $450.00.The studs,bearings/seals would be installed on the axles when you recieve them,so you just remove them from the box,& slide them in.

 

ok... so ur saying the complete Timken rebuild kit (minus the A9 and 712146 axle bearings/seals since you say they will already be installed on the axles) is NOT included then?

 

That is correct.If you want all of the other bearings & seals to do the entire rearend,the total would be $550.00 with the shipping included.
An Eaton posi & Motive gearset,along with everything above,would be $1200.00 with the shipping included.
Make sense?

 

yesem. Price is ~ the same as monzaz, so just contemplating.

Do you accept Paypal payments? Also, what about warranty issues with the Moser if any pop up? Am I going to have any problemos dealing with them? And... what is the turnaround time getting custom axles from them?1 day? 1 week? 1 month?

 

I myself haven't had ANY issues with Moser axles,so I have never had to do any type of warranty work with them.I also know what axle to choose for each application to prevent any happenings like that.Turnaround is about 10 days.
As for payment,I do take paypal,but they take a chunk out on a $1200.00 payment,so if you are going for the whole package,make it $1250.00.
The other recent problem I have found with Canadians sedning cashier's checks,is that the ones of that size or more will have a 45-day wait on them.I have no idea why,but is not just my bank.I built a 4-spd for a guy in Sask,& a 12-bolt chevy rear for a guy just east of Sask,& that rule applied for both,but neither was in a hurry,so it all worked-out.

**Another tidbit of info to pass: For you guys that go to AutoZone,they are doing an overhaul of their inventory & product lines.They are not stocking as much Timken products,& may eliminate them altogether.For example:The SET-9 wheel bearings that have always been on the shelves are now all of a sudden not even an item that can be ordered.I think your new choices will be China or Japan.Good thing I have Erie Bearing around the corner.

 

could you swap the Eaton posi and motive gear for an Eaton trutrack with Yukon 3.73 gears?
