Sterling 10.5 Questions

I suppose, but who the hell bought a 60K SD at the dealer, and said fuck i really with i had some 5.38s for this thing. cant imagine there were too many at the junkyard yet. :grinpimp:
I bet a bunch of who bought 2wd white fleet trucks with the intention of rolling around at/over GVW wished they had deeper gears.
 
Also this this end....I assume if you are keeping with 2011+ stuff. You would have to use a companion flange as I cannot find any other yokes for the 37 spline pinions.
 
Are you worried about being on the hairy edge of joint angle? If not, I would run a flange over a yoke every time.
I will likey run the flange. I will probably run the same flange pattern on the front, and then make a driveshaft that can fit both as a spare.
 
my google skills are failing me today so flame away as im sure this is simple

what are the different wms of a srw Sterling. i know 84-97 are the same but how much wider are the 99-04, 05-10 and 11-current 10.50s ?

cant speak on the 11 up. but i originally had an 03 sterling and an 06 sd60. the 03 was noticeably narrower than the front. looked like ~2" narrower. i swapped in an 08 rear and they look the same width now. i was always told the 99-04 were 69" and the 05 up were 72"

google skills are better today and looks like 84-97 is 65.5, 99-04 is 67 and 05+ is 70.125. currently running a 84-97 axle but run 2" wheel spacers so looks like a 05+ diff will give me same width without the spaces :smokin:

99+ will have a metric bolt pattern
 
easy to redrill
The backside of the hub looks like this. Honestly I think the width difference is in the hub so you might as well just keep the spacers. I run a spacer/adapter for mine.

Yall seen many broken stock sterling shafts? They hold up pretty much as well as 14 bolt?

A buddy of mine has broke two stock shafts in over 4 years of wheeling his 6.0L-powered ~3,800Lb buggy on 40" stickies, but he is also on his 3rd set of stickies, so he wheels a lot. He was running the same Sterling in his 1 ton Cherokee for a couple of years with a 150:1 crawl ratio and 42" Pitbulls and later 40" Black labels before the buggy and never broke anything on the Sterling. It has also been welded the entire time. I would say the stock shafts are pretty stout for your average trail wheeler.

Would you personally rate them above or below OEM 35spl Dana shafts?
 
Not sure if this is the right place for it, but I run a Revolution Gear and Axle set in my 05 sterling with 5.38s and it came with a crush sleeve. I was able to use the Yukon 9" part number on the sterling pinion and it fit perfectly. Part number

I am running 40s on my axle and have yet to break anything on it (02 Taco with 3.4 auto trans)
 
I seen one 10.25 shaft break a couple years back, 44's and big block buggy guy beats like a bouncer.

Sterling shafts have a 45° pressure angle instead of the 30° angle like Dana Spicer, so the splines have a larger minor diameter and I am pretty sure Ford uses 1541H for their shafts whereas I believe Dana Spicer uses 1050. So yes, I do belive Sterling shafts are stronger, and if I am correct about the materials, then the Sterling shafts should be about 12% stronger according to this old Petersen's article:

1340: This high-manganese grade was the OE material years ago. Many early Dana/Spicer axleshafts used 1340. Modern higher-performance applications need stronger material.
1040: OE axleshafts are typically made from induction-hardened 1040 because it strikes a compromise between strength and ductility. 1040 is also easier to machine than harder alloys.

1050: Thanks to its higher carbon content, 1050 is about 38 percent stronger than 1040. It is used in certain OE applications and also for some aftermarket OE-replacement shafts.
1541: This high-alloy grade is popular with aftermarket manufacturers.
1541H: An even better aftermarket shaft material, this grade adds silicon to 1541 to increase strength and heat-treatability. 1541H can be 50 percent stronger than OE 1040 and about 12 percent stouter than 1050.
4140: 41xx designates the chromoly group. Chromium offers three benefits: improved hardness, better elasticity during quenching, and greater corrosion resistance. Molybdenum and nickel further increase hardness. This steel is also commonly used for U-joints, spindles, and camshafts.
4340: Also in the chromoly family, 4340 is about twice as strong as OE 1040. It is also ductile enough to absorb the shock of abrupt acceleration, taking some load off of the differential. 4340 is popular for performance-aftermarket front shafts because it is strong and more affordable than some of the more exotic alloys.
300M: Also known as 4340M, it is similar to 4340, only with vanadium added plus additional silicon and slightly more carbon and manganese. It is mainly used in aircraft applications where high strength and ductility are required for such components as landing gears. 300M is also normally through-hardened and is about 150 percent stronger than OE 1040. It is expensive, harder to machine than other shaft materials, and manufactured in much lower quantities than the other steel grades.
Hy-Tuf: (ASM-6418, SAE 4625M4, MIL S-71083, aka Maxi-Drive) is a chromoly well known in drag racing circles. Strange Engineering and others sell Hy-Tuf shafts that have a Rockwell (HRC) hardness rating of 46-48 throughout. (Hy-Tuf is generally through-hardened.) The recipe is high in silicon and manganese. Hy-Tuf is more affordable and available than 300M.

Good info thank you

Any idea what the old 30 spline ff 60 rear shafts are made of? I popped those easy back in day.

How about 14 bolt shaft material?

I think most OEM shafts are made from 1040/1050. I have only ever seen references to the Ford Visteon Sterling axles (8.8, Super 8.8, 9.75, 10.25, 10.5 and likely the new 11.6) having 1541H shafts from the factory. 14 Bolt shafts I think are slightly larger diameter than 35 spline Dana Spicer stuff, so I think they are pretty comparable to Sterling 10.25/10.5 shafts. The biggest advantage of a 14 bolt is the gear set, especially since all of the aftermarket gear sets for the '99-'10 10.5 are really 10.25". The '11+ 10.5 closes the gap a bit with the massive 37 spline pinion, but you are limited to 4.88 with aftermarket ratios in those.

Are they still using 8x170 and the same ol' wheel bore diameter on the newer super-duties with the 11.6?

I couldn't say, but I haven't seen anything about them changing.

EDIT: according to Google, they are still 8x170mm, still no idea on the hub bore diameter.
 
Does anyone know if the brake parts (rotors, calipers, and hangers) from my 2011 10.5 will fit a 2005-2008 10.5?

This thread just helped my decide to scrap my 2011 housing I had stripped and welded new perches to and now tried to set my 10.25 gears up and realize the outer pinion race is .250" too small.☹️ I'm going to grab the E-locker and 10.25 gears I have and find an earlier housing. A wrecking yard near me has a 2006 Sterling for cheap enough but no brakes on it. Thanks

Rock auto shows same part number for srw rear calipers. So I would assume yes.

When I looked up the rear calipers on Rockauto for a F-250, it showed 2008-12. That's why I was wondering if I could pull all my (fairly new) brake parts and swap it all to another 2005-2007. The 08 should fit but it requires a spacer from Yukon to make the 10.25 gears fit which could work too.
