Fishboy's Weight Weenie Thread

[cracker]

Got the Warn drive flanges and they ended up being a fraction lighter than the Tera flanges I got. (1/5# overall)

Fishboy, got your weights yet?

 

[Matt S.]

My wieght chasing days have begun ladies...

 

[Paul S]

Ok, let's get back to weights, BJ/unit bearing weights:

Knuckle = 23 lbs

Inner knuckle = 16.5 lbs

BJ = 3 lbs

More to follow...

[Paul S]

Caliper bracket = 4.5 lbs

Unit bearing = 15 lbs

Rotor = 17 lbs, no photo.

CTM = 3 lbs

Looks like the BJ/unit bearing setup is 12 lbs lighter per side than the KP/spindle setup.

them's some big ball joints. my D30 just felt inadequate.

 

[BrettM]

cross-drilled rotors? i'm sure you could get by with a few holes in those caliper brackets... and you haven't drilled the knuckle for the TRE yet, that's another couple ounces...

 

[XJ_ranger]

hmm.

all that stuff is WAY too heavy...

The Zuki samurai stuff we are using for the mini baja front axle is 30 lbs for:
inner + outer, inner knuckle, spindle, stub, hub, CV, and bearings...

for both sides...

with a 30 pound differential, and all we have to add is the axle tubes, rotors, and calipers/brackets... I dont think we're doing too bad...

just wait for the pictures with weights when I start makin the housings - were shooting for a 100lb or less front axle and a 75lb or less rear axle... including brackets and gear oil...

Is life expectancy calculated in feet?

nope...

shooting for a 500lb rig, 650 with driver...

powered by a Briggs and Stratton 10 horsepower 'lawnmower' engine

with about 45:1 in low and 30:1 in high...

i think sami stuff that was built to hold a 2500lb rig and a 63 HP motor should do just fine in this use

I've always said those sami axles looked like they belonged in a go kart. that sounds like exactly the go kart my kids need.

Bad Paul! You should not be stealing Opie's account!

You guys are doing an AWD mini baja? Neat. We thought about doing that but decided the benefits wouldn't be worth the added cost and design time...then again we had the water crossing event instead of the rock crawl. :lame:

So Paul (or Goatman or Dave, or anyone else who knows), can you give me a run down of who makes this stuff or what it is from? Oh yeah, what they cost too.

Inner C - for 3" diameter tubes and one ton Dodge ball joints? Crane?

Steering knuckle - I have no idea what this is for or who makes it. It looks custom. Crane?

Ball joints - Moog? For 1 ton Dodge trucks? Same part for 1 ton Ford trucks?

Unit Bearing - Dodge 3500? Stock bolt pattern or modified? If modified, who does it? 33 spline. What's wrong with the stock Dodge outer axle shaft? I believe you are getting some 300M inner and outer axle shafts made by CTM, but I'm just wondering how the outer differs from the stock outer shaft. How about Ford unit bearings? How do they differ from the Dodge units? What is the difference between F250, F350, and F450 unit bearings? How about Chevy unit bearings? What's the specs on those?

Brake bracket - I assume it goes against the steering knuckle and is sandwiched by the unit bearing, right? Who makes that?

Rotor - Something custom I imagine. Who makes it and I imagine it has the right offset to position it correctly for Large GM calipers?

Calipers - I'm guessing you'll be using vintage Large GM calipers which are the same ones a number of folks are using on their 1/2T D44 front ends, right? How's that going to work with 40" tires?

Thanks for the inf. Jeff

Inner C’s with 3” ID are from Parts Mike. $189 for both sides.
Steering knuckles are Tera. I think list is $350 or a little more, per side.
Unit Bearings are Dodge 3500, 33 spline. Tera modifies them for 5 on 5.4 & 5 on 5.5. $175 each, including mounting hardware & wheel studs.
I think the F450 unit bearings have the same mounting as mine, but I’m not sure. They have mini wheel hubs & require locking hubs or slugs, which is why I didn’t want them. They are 35 spline.
The 450’s are about $350 each, + a couple hundred for slugs.
There is also a Dodge ½ ton, 33 spline, 3 bolt unit bearing. This is the one that Spidertrax uses.
Stock Dodge stubs would work, but they’re not 300M.
Alloy USA inners would most certainly be fine, but with CTM joints & stubs, it just seems to make sense to spend a little more for the piece of mind that comes with balance:laugh3: + we’re not buying any spare anything.
Rotor is stock early model CJ.
Caliper brackets are Tera, mounted as you noted.
Calipers are standard ½ ton GM. I won’t even have to bleed my brakes.
I assume they’ll be fine with 40’s, if not there are plenty of options to go to larger claipers &/or rotors.

Good thing since you're gimp & can't bend over anymore... Does this mean your relationship with Dave is over now?:eeks1: :wierd:

 

[FarmerMatt]

OH SNAP!!! I've still got grease...

I tore the front end out of the rig to finish fab & weld on the housings along with freshining up the knuckles with new ball joints & such. I never opened them up before... Sure looks like a spindle with taper bearings to me & lots of nice slippery lube. The one nice thing is that I can get to the spindle nuts without getting into the grease by going between the rotor & knuckle so greaseless axle swaps are still a possibility (if I ever need to again). Getting back to the theme of this thread, I guess this will add a few pounds to me per side...

Hey Paul.....

Not bad. Is that trail ready ? Now you need to keep it at that with a real front
axle, tires and t-case.

Not trail ready. I plan on weighing everything as it goes on. I wont have a whole ton of stuff to add for the trail. Front shafts, minimal tools, tow strap, spare fluids, me and my passenger. I figure probably 400 to 500 lbs extra for wheeling status. I still think 3700 loaded for the trail is damn good. I hope for less, but my initial goal was to be under 3800.

I'm sure you will like it this way. Good jod on the diet.
