Just a quick, well, not so quick status update for the fellow membership and friends.
We are pretty resolute about moving to Kentucky this summer. The original target was early June, but as I suspected this proved to be too much of a challenge in the time/money ratio aspect. To be honest, that would put my chances of making it to Ouray much less favorable as well. Currently the target is July. Tentatively (don't go telling my boss!) I will finish work on July 5th, take off for Kentucky (targeting the Warsaw area, but anywhere between Cinci and L'ville works fine) with a u-haul behind the Suburban and hope to arrive by the 11th or 12th. We dump out the u-haul, get a good nights sleep and then Cristy can take me to the airport so I fly back to WA for the Money Badger! The morning of the 14th I start all over again with a week long pitstop in Ouray! If this board had a dancing banana smilie, you'd see it here.
So 2500 miles is a long way for 25 year old truck, and I'm talking about my trusty Captain Ameritruck (the burb) so most of my effort has been directed towards that the last few months. I've serviced everything I can possibly service; including new rear wheel bearings and seals, and all that's left before I put it back on the road is the headliner.But laying underneath it, every time I look out the garage I see this staring back in my face.
He's saying "HEY YOU GUY!!! MY SINCRO'S ARE WORN AND YOU PROMISED A FULL FLOATER BEFORE OURAY!!"
My trip last year was a blast, but I held back a lot worrying about the return trip. I couldn't afford a major breakdown in Ouray and I couldn't be late returning to WA due to Army obligations. This year I intend to have a little bit of time buffer, but more importantly I intend to be a little better equipped. I've taken care of my engine issues and have boned up on Holley tuning for altitude. My primary concern is the rear end. I know full well that a D44 can handle my 31s (and even 33s if the right deal comes along in time) just fine considering my driving style. What scares me about the stock rear axle is how often they fail at the wheel bearing ON THE HIGHWAY.
With no warning either the axle slips the bearing and flies off still attached to the wheel, or the axle sheers right at the bearing. I saw it happen to Carnucks truck (before he owned it), and remember a thread on the motherboard where 10-15 people posted pics of the same. Flint knows what's up.
I saw three options for this, all are valid for certain circumstances, but I made my choice and I'll explain why even though I know many will dissagree.
The obvious choice is a D60 from a J20, BUT they don't exist when you want one, and if the stars align and one becomes available, it's too far or too expensive. On top of that, it would require swapping the front over to 8-lug and new tires/wheels which just adds to the cost of the axle and reworking the axle (bearings and possible gear change). All in all, when I crunched the numbers for this, using the J-20 D60s for sale that are way out of my area as a general price guide I was still looking at over $2k (remember the rule of "whatever you think it will cost, double it", this is before that rule takes effect). On top of that the only tangible strength I gain is in the full float aspect, while I double the weight and reduce the ground clearance, decrease the availability of replacement parts and increase said parts replacement costs. I think I wrote this option off pretty quick due to the price, but even then when I looked at the pluses and minuses it seemed like giving too much to gain what little I wanted.
For the last year, my preferred option was custom building my own 14FF. I had the plan to pick one up from a van, the really wide one. Then I'd pop the tubes out of the pumpkin, cut down the passenger side tube and weld it back in to take the drivers side shaft. Then I'd get a longer tube for the drivers side to take the passenger side shaft, giving me roughly 7" offset to the passenger side similar to the stock axle to clear the gas tank without stupid tall lift. All in all, this was a pipe dream. I wanted to do it to inspire q-trac guys to realize a 1-ton option for their trucks. As it came down to it, while shopping for 14FFs (and I found plenty, but they don't just fall out of the sky) I realized I don't have room for one. I get away with murder considering I live in an apt complex, but I can't have a garage AND a reserved spot and then park a car in the open parking so I can use my garage to build an axle for a month, especially when I share that garage with a guy who has nice cars. This got me to look at the drawbacks a little harder. I don't want to go bigger than 33"s because I love driving my truck everywhere all the time. Bigger tires cost more to replace and burn more gas. This would make the ground clearance loss due to the huge pumpkin a big deal. Also, the 14FF is stupid heavy and I have a 304. Add this to the same downsides as the D60 and the D60 starts to look a lot more appealing.
So I thought really long and really hard about what exactly I wanted from an axle upgrade.
1) I want to eliminate the D44 wheel bearing failure point.
2) I want a cheap, non-critical, easy to replace fuse in the driveline.
3) I want a locker.
My problem solving process is pretty simple. I come up with a possible solution, then I ask "Has this been done before?", if no I ask "why not?", and if so I ask "will the results meet my goal?". I came up with my possible solution to Want No.1, full floating the D44. I looked to see if it had been done before and it has, several different ways even! None of the ways was a direct instruction book for what I wanted though. They all revolve around putting front spindles on the rear axle but none of the ways it's been done that I found works for me. One way is to bolt the spindles (after turning down the pilot to fit where the wheel bearing used to be) right where the bearing retainers go. That's too flimsy for me. Another is an aluminum adapter a guy at pirate made that fits the bearing bore in the axle and has a pilot bore for the spindle, but my axle is wide enough, and I'd like it to be a little more sturdy and fewer pieces. I'm going to machine some new flanges, cut off the old ones and weld the new ones on. Surprisingly there are some definite pluses that go with this. First, disc brakes are pretty much automatic, but more importantly, Want No.2 came forth right quickly, in that I will have cheap lockout hubs as an easily accessed driveline fuse. In fact, I can carry one rotor/hub + spindle assembly from any 1/2ton straight axle Chevy as a spare and ALL FOUR corners are covered for spare parts! This also covers Want No.3, since lockers, even full carrier lockers for a D44 are about half the cost of a D60 or 14FF.
I've crunched the numbers that I can and I'm <$300 for everything EXCEPT...axle shafts.
That even includes an adjustable proportioning valve from Summit since I'll have disks in the back.
Now, back to the shafts, remember I live and work in the shadow of Boeing. There are machine shops all over the place. I talked with a shop with some rough measurements that will cut me shafts for $200-$250 a shaft in 4140 ChroMo. Once I do some math and get some better measurements, I'll call Dutchman and Moser to see if they can make what I want and get an estimate. But check this out
, if I can get a hold of a lathe using my own cutters bars and bits, I can cut and join front axle stub shafts to rear axle shafts and weld them up to make shafts splined on both ends for the carrier and then the hub for about $75 a pop! I figure I'll buy one set and make one set. I'll test fit them both, but I'll run the homebrew ones until (if) they break and then swap in the custom ones. If the homebrews last a year then I'll swap in the custom shafts and keep the homebrews as spares.
At some point I need to cough up $240 for a T18 rebuild kit too though. If you caught it above, my synchros are just about shot.
