  • What's the proper method for setting and checking torque?
   

Fixing a sloppy shifter.  A quick and dirty little article about fixing the notorious SM465 sloppy shifter problem. Worth a look for other manual tranny owners too, as the fix will likely work for other models too.

Best of all - it showcases the incredible talent of my new graphic/technical artist, Lonny Handwork. Check out the full size pic of the 3D cutaway of the Sm465 shift tower - amazing!!

 
  2004 Articles
   

Inside the Dana 20.  Part 2 of project "Uber-20", this is a combined tech article / product review showing every single step of the teardown and re-assembly of a Jeep Dana20 transfer case with the Tera Manufacturing Low20 3.15:1 low range kit.

Also includes some calculations and discussion on available gear "ratio stepping" - a concept of great interest to all - regardless of which transfer case you run.

   
Speedi-Sleeve Install.  A "mini-tech" article showing how I saved my nasty 14Bolt spindles and cured my perpetually leaky rear wheel hubs with the trick Speedi-Sleeve from Chcago Rawhide.
   
The BillaVista 60 Project.   My hugely ambitous project to build, at home, with modest tools and average skill, the biggest baddest Front 4x4 Dana60 axle posible, using the latest and greatest commercial, off-the-shelf components from the top names in the business.  Complete article combines tech articles on axle shafts and steel/material with no less than 6 thorouh product reviews.
   
Axle Shaft Technology A part of the BV-60 project, this article also stands alone as a pretty thorough discussion and examination of modern axle shaft technology - from the materials and heat treatment methods used to the forming of splines.

  2003 Articles
   
Hydraulic Steering Bible. An awesome collection of tech on hydraulics and hydraulic steering systems. Not just how to design and install hydraulic steering in a 4x4, but system troubleshooting, reservoir design, hose and fitting catalogues - the works.

Front Dana 60 Axle 35 Spline Stub Shaft, Drive Flange, and "BIG" Inner shaft tech. Detailed installation of "Big" (non-neckdown, 1981+) inner axle shafts, Dana 70 35 Spline stub shafts, and Warn 35 Spline Drive Flanges in a Chevy dana 60 front axle. Ever wondered what the differences between the "small" and "big" shafts were? What the 35 spline stub shafts are like compared to the stock 60 30 spliners? Exactly what drive flanges consist of and how to install them? Well, it's all here - detailed pics, specs, etc. Also detailed instructions on installing u-joints in axle shafts, and what the heck are all those seals on the stub shaft and in what order/orientation are they installed? Read it here!
   
Kingpin Rebuild. Complete specs and pics of a Dana 60 front axle kingpin rebuild. Includes exploded diagrams, part numbers, and the US military CUCV manual on the procedure. Also - see my cool little custom grease nipple skidplates!

From definitions to operating principles, geometry to maintenance, this is a MASSIVELY detailed look at all you need to know about driveshaft tech. Includes product review of the 4x4 world's finest driveshaft - the famous High Angle Driveline 1350 CV shaft.
   
One Ton Rear Axle Disc Brake Conversion. Extremely detailed look at how I added disc brakes to the GM Corp 14 Bolt rear axle in the Wolf.

Also contains excerpts from Military 14 Bolt maintenance manual on axle shaft R&R and wheel bearing R&R and adjustment.
   
Project Uber-20. An ambitious little gig to build an Atlas-killer transfer case at home, bit by bit, as time and money allows. Start with one dime-a-dozen Jeep Dana 20 transfer case, add a handful of the best upgrades and add-ons available, and hopefully end up with a truly world-class transfer case. When it's done, recruit one friend with digital video, go do something insane with the skinny pedal, and report back the results. Part 1 complete....more to follow.
   
Tapping a Power Steering Box for Hydro Assist.  A quick and dirty one on how and where to tap a standard power steering gearbox for Hydro Assist steering.

  2002 Articles
   
The Wolf's new Paint.  A short article to show what can be achieved as a super-budget paint job in the driveway with a can of rust paint, a brush, and a few rattle-cans.  Really an excuse to show off pics of my rig, as much as anything else!
   
Tow Rig.  Not so much tech as humour.  Some good I.D. shots of a Ford RC Dana60 front axle though. 
   
Trailer.  Read along as BillaVista "scores" a dual axle trailer for $900 Cdn, then realizes it will take at least another $1500 to make it road worthy and legal.  Follow along as our hero dumps paycheck after paycheck into a 35 year old trailer - see what he learns along the way.  Contains some good tech info on mobile home axles.
   
Bill's Buggy.  See all the pics, specs, and details of BillaVista's latest rig - a multi-link, coil sprung, 350 powered, dual 'cased, one ton driven, Military tire shod, rip-snortin',  home-built wonder.

Dragging Junk Home.  'Nuther humorous article about me wasting time and money in a foolish quest for cool 4x4 parts.  Read and laugh along - heck, show it to your spouse and proclaim "See hon, I'm not the only complete loony!"
   
Valve stem protection.  A quick but really cool article about re-locating valve stems for better protection.   Cure that notorious weak point once-and-for-all.
   
Dana 70.  Unfinished work of art about the big, bad Dana 70 rear axle.  Some good Dana 70 1.5" vs Dana 60 1.31" axle shaft pics, and some spindle bore measurement comparisons too.  I hope to add more info to this one when time allows.
 
  2001 Articles
   
Hybrid Axle.  A crazy ambitious project of mine - take my XJ's Front RCD30 (with it's 4.56 gears and Detroit Locker), cut off the inner yokes, weld on CJ D30 inners, then bolt to them Chevy 1/2 ton D44 from the knuckles out - with the idea being to retain my gears/locker investment, the light weight and high clearance of the D30, but get real locking hubs, bigger u-joints, stub shafts and balljoints as well as "flat top" knuckles for "high steer".  Sounds great - see how it turned out.  Of interest to those considering other Hybrid's too (like D44/D60) as the principles will be similar.
   
Steering Pages.  Five separate sub-articles - four being versions one to four of the high clearance crossover steering I built for my XJ's custom hybrid D30/D44 axle (but with info and principles applicable to other steering systems too) and the fifth being all about custom steering - focusing on the popular Dana 44 "Hy Steer" High clearance steering system.

Also shows exactly how to identify "flat top" knuckles, and how to convert Chevy/Jeep D44 5x6.5 outers to Ford D44 5x5.5 bolt pattern

   
Anti-wrap bar.  Booty fab homebrew ant-wrap bar for rear leaf "spring-over" suspension, built for nearly nothing out of tractor hitch "top links" and a piece of tubing.  Ugly but effective.
   
D44 Buildup.  See me find an XJ D44, strip, clean, and paint it, add 4.56 Spicer gears, Detroit Locker, ZJ disc brakes, a custom truss, and slap it in.
   
Disc brakes.  See me convert an XJ Dana 44 rear axle to ZJ disc brakes with integral parking brake.
   
Dual battery.  My super-simple bullet-proof dual battery setup using a HUGE orange marine battery switch.  The setup isn't remarkable, but there's good electrical, battery, and switch tech included, as well as cool marine electrical suppliers.
   
Leaf spring conversion.  The best, and cheapest, way to rid an XJ of the terrible geometry of a 9-10" lift ......convert to spring-over leaf springs in front!
 
  2000 Articles
   
Rear bumper  Low buck home-made rear bumper with receiver hitch and D rings for towing, plus a swing out tire carrier that also holds a Hi-lift jack, two 20L NATO jerry cans, and steel ammo boxes for tools and parts.  A little over-the-top but perfect for crossing a continent....and I was just learning to weld and couldn't put the thing down.
   
Snorkel  Is it booty fab if I make a snorkel out of a dryer vent and abs pipe?  Oh well - it was cheap and effective.
 
  1999 Articles
   
Front bumper  Back before I even owned a welder, my good buddy Karl Charest helped me build a custom XJ front bumper and brush-guard.
Box rockers  Way back when - I believe I was one of the first to cut out my unibody XJ's rocker panels and replace them with rectangular structural steel tubing.  Still one of my favourite mods.
Roof rack  The first home-made mod for my XJ...a cool steel safari-style roof rack that Karl built for me for next to nothing.
